120 “Passion XI”, is getting as much of the work done as he can while the hull
is upside-down. Each time that I have turned the hull of one of my own big boat
build projects it has rained the next day, turning my hull into a paddling
pool. That possibility encourages a builder who doesn’t have a workshop large
enough to house the new build to do much work that might otherwise have been
left for when the boat was upright. I once visited a builder of a Didi 34, with
the hull still inverted. He had the interior almost fully complete, including
all painting, trims varnished and locker and cabin doors varnished and hung. All
of that work had been done by a meticulous builder to a standard that few can
achieve.</span></p>
<span lang="EN-ZA" style="line-height: 107%;"><span style="font-family: arial;">David is also doing some of the work
needed for mechanical systems in his boat.

propeller shaft must be accurately aligned with the output shaft of the gearbox
on the inside of the boat and the bearing of the P-bracket on the outside. In
practice, the motor/gearbox, hole through the hull and the P-bracket are all
aligned with each other and each can be fine-tuned during final installation to
ensure proper alignment. Inaccurate alignment can create future problems over
the life of the boat. In this photo, the hole through the hull has been bored
and a wooden dowel of the same size as the shaft is being used to guide the
work. The P-bracket is lying on the hull.</span><span style="font-size: 11pt;"><o:p></o:p></span></span></div><p class="MsoNormal" style="font-size: 11pt;"><span lang="EN-ZA"></span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi6YoPLwgEUtFByUGXGwyfFHOEattqpbivvfxfyjEd3E5t47iMzIWHIbC1ys8ksDpdH36-NGRmR218A4q2XmzE69Bye592J66SIi_q64lePUVFiJblUovfafY04U79RY9l7ZXo0dIItVlw-QhOojd6ex6WAOwsAnxgu3Z_CVk9ABfTk3HY9yM8xZtUvBbo/s2048/Didi%20120%20Photo%2035.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi6YoPLwgEUtFByUGXGwyfFHOEattqpbivvfxfyjEd3E5t47iMzIWHIbC1ys8ksDpdH36-NGRmR218A4q2XmzE69Bye592J66SIi_q64lePUVFiJblUovfafY04U79RY9l7ZXo0dIItVlw-QhOojd6ex6WAOwsAnxgu3Z_CVk9ABfTk3HY9yM8xZtUvBbo/w400-h300/Didi%20120%20Photo%2035.jpg" width="400" /></a></div><br /></span><p></p><p class="MsoNormal"><u><span lang="EN-ZA"><span style="font-family: arial;">Photo 36.</span></span></u><span lang="EN-ZA"><span style="font-family: arial;"> The

securing it at the correct height and angle for least binding of the dowel in
the bearing. If the stainless steel shaft is available then it can be used
instead of the dowel but the light weight of the dowel makes it much easier to
work with. The dowel must be truly straight and round or accuracy will be
sacrificed.</span><span style="font-size: 11pt;"><o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"></span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjGUFBFooHLG_nvm1LZV0DddzYR4KW82Jjshn6Dvc4OUw9JvHpDF8CA5mipm_j0Sq0Gz6LUwTu5CfRgdzo3GuB_Pd_uLqsiuhOiVEe0fQ9HwlVi2LoqmJLdUx5YXxQ4sItYPDkywiRNpzQ3V2j7QS-XtuLOyANE0tbW342T4ZascEKwyVO8lOlld2J2jgs/s2364/Didi%20120%20Photo%2036.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1773" data-original-width="2364" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjGUFBFooHLG_nvm1LZV0DddzYR4KW82Jjshn6Dvc4OUw9JvHpDF8CA5mipm_j0Sq0Gz6LUwTu5CfRgdzo3GuB_Pd_uLqsiuhOiVEe0fQ9HwlVi2LoqmJLdUx5YXxQ4sItYPDkywiRNpzQ3V2j7QS-XtuLOyANE0tbW342T4ZascEKwyVO8lOlld2J2jgs/w400-h300/Didi%20120%20Photo%2036.jpg" width="400" /></a></div><br /><p></p><p class="MsoNormal"><span style="font-family: arial;"><u><span lang="EN-ZA"><span>Photo 37.</span></span></u><span lang="EN-ZA"><span> The

The aft end of the hull has received careful treatment. A sharp corner on a
wood surface doesn’t hold finishes well and is easily damaged, with the
potential for water to enter through unseen damage. This corner has been
rounded to a radius that will hold the finishes and allows the bottom glass to
be wrapped onto the transom. The corner is then built back to a sharp edge with
reinforced epoxy to create a much tougher corner. There is good reason for
this. Water flowing off the bottom at low speed hangs onto the surface and is

skin. This changes the skeletal framework into what looks like a boat.</span></span></p><p style="background-color: white; color: #243961; text-align: left;"><span lang="EN-ZA" style="background-color: white; color: #243961; line-height: 15.8895px;"><span style="font-family: arial;">Photo numbering continues sequentially from post to post.</span></span></p><p style="background-color: white; color: #243961; text-align: left;"><u><span lang="EN-ZA"><span style="font-family: arial;">Photo 22.</span></span></u><span lang="EN-ZA"><span style="font-family: arial;"> This
view of the bottom structure of the hull shows the keel support grid,
comprising backbone and keel floors. All have to be shaped by means of planes
and belt sanders to form a fair surface for the plywood sheets to lie on, with
contact with all surfaces to which they will be glued. This includes forming
the dihedral (V-shape) onto the keel timber, which can be seen as having a peak
on centreline. A guide for planing is created by using a long hand saw to cut
into the backbone at each bulkhead, cutting down until the saw teeth just touch
the edge of the bulkhead. The saw-cuts from the two sides will meet on
centreline of the keel timber and planing down to the bottoms of those saw-cuts
creates the required V-shape. Between bulkheads, the keel floors, stringers and
tangent stringer can be used in the same way with the saw to make guide cuts. Limber
holes run through all solid timber alongside stringers etc. to lead bilge water
to the low points, where the bilge pump strum boxes will be. These openings must
all be sealed either with multiple coats of epoxy or ¼ sections of PVC or GRP
pipe bedded in epoxy. If you are wondering what the blue patches are in the
limber holes, as I did when I saw them, they are reflections of the blue sky
above in the gloss surfaces of the epoxy coatings.</span><o:p></o:p></span></p><p><span lang="EN-ZA" style="background-color: white; color: #243961; line-height: 15.8895px;"></span></p><p class="MsoNormal"><span lang="EN-ZA"></span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjdWttaC1A456IyyqaXZy23oP9fHdfJA2G6XTdeKa26oVCSR1lLv4_r-q0f7_mRarJf3V9aak30jqQvCi1WRNJjYDbV4SGUF2pmm5oeqJRzosAI_0qzlMDYAA1cLlXGi3JLr3UmOzdy6GFgEEXL6kGSb2VBVxQYHz5OYr1T4tsEtL-Fyy76mBMK04GvRI4/s2048/Didi%20120%20Photo%2022.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjdWttaC1A456IyyqaXZy23oP9fHdfJA2G6XTdeKa26oVCSR1lLv4_r-q0f7_mRarJf3V9aak30jqQvCi1WRNJjYDbV4SGUF2pmm5oeqJRzosAI_0qzlMDYAA1cLlXGi3JLr3UmOzdy6GFgEEXL6kGSb2VBVxQYHz5OYr1T4tsEtL-Fyy76mBMK04GvRI4/w400-h300/Didi%20120%20Photo%2022.jpg" width="400" /></a></div><p></p><p style="text-align: left;"><u><span lang="EN-ZA"><span style="font-family: arial;">Photo 23.</span></span></u><span lang="EN-ZA"><span style="font-family: arial;"> The
cockpit sole and seat fronts have been installed at a convenient stage of the
assembly of the skeleton and is bonded to the bulkheads. The cockpit increases
the rigidity of the structure to help it to hold shape during construction,
helping to resist the forces applied by the multiple longitudinal timbers that
are all pulling in different directions. It is also much easier to finish these

of the interior joinery can be built before the skin is fitted. The settee
front and top can be seen at the top of the photo. Below that are the shelves
that will be behind the backrest of the settee. Fitting them before the skin is
fitted is quicker and easier than doing it later in the upright hull and the
dust and shavings fall onto the ground instead of having to be vacuumed out of
the nooks and crannies inside the boat. If fitted into a skinned hull, the
edges of shelves and divisions must be carefully cut to fit against the skin.
If fitted first they can be cut a few mm over-size, then easily planed back to
the correct line for a good fit. It is a bit awkward to fit the shelves,
fastening them with temporary panel pins to the triangular fillets, working
upside-down. But it is well-worth the effort to do it this way.</span><o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-ZA"></span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi6yEm-PgbLQbQieLgioT0ykeM5qvGcNRloTKNfZETSFEFg7vf1CszrJBzymAXRxrWkOYZW0Wc3cLKCYptk9l3tSWr4wV8ZQBX-KeT32R195Gcag8PgC5mvP9HKopBlgWBDS-7mpTq5bYncaKDxkT6mDfERa4Eo03roUO75F5QKwfjJUEI2-HcDavXhSbk/s2048/Didi%20120%20Photo%2025.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi6yEm-PgbLQbQieLgioT0ykeM5qvGcNRloTKNfZETSFEFg7vf1CszrJBzymAXRxrWkOYZW0Wc3cLKCYptk9l3tSWr4wV8ZQBX-KeT32R195Gcag8PgC5mvP9HKopBlgWBDS-7mpTq5bYncaKDxkT6mDfERa4Eo03roUO75F5QKwfjJUEI2-HcDavXhSbk/w400-h300/Didi%20120%20Photo%2025.jpg" width="400" /></a></div><br /><span style="font-family: arial;"><u><span lang="EN-ZA" style="line-height: 107%;">Photo

The side and bottom panels have been completed, leaving the radius still to do.
This is looking into the water tanks under the settees, for which all joints
must be totally watertight. It is easiest to seal as many of those joints from
outside as possible before doing the radius skin rather than trying to do them
through the hatch openings after the completion of the skin. The edges of the

The plug from which the moulds were made was built from plywood and until now that is the only plywood one that exists. All of the drawings were for the GRP construction method. I have now detailed this design for building from plywood, with build methods suitable for amateur builders. It is fairly standard lapstrake plywood detailing with fibreglass tape to reinforce the longitudinal joints between panels.</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgRpk55qFqQRtb4L9n7w4vvVXHcJ6KHEbqTqaiQyjzj77t9ee3eUsYdIGnas6jsbH7Q4UZuo8clbqzGJMKNcPKl5dPY1UR9AsPHX59JWwHgAeP_BwRft8hB2jzJxKDQKqWfnA6zMhHYElBYtP1UrdFfcTlVXd5ykUsM02WPpFf_KFbA8ITkJcNvPgDRq7U/s707/April%202016%20Regatta%20pics_1.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="696" data-original-width="707" height="394" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgRpk55qFqQRtb4L9n7w4vvVXHcJ6KHEbqTqaiQyjzj77t9ee3eUsYdIGnas6jsbH7Q4UZuo8clbqzGJMKNcPKl5dPY1UR9AsPHX59JWwHgAeP_BwRft8hB2jzJxKDQKqWfnA6zMhHYElBYtP1UrdFfcTlVXd5ykUsM02WPpFf_KFbA8ITkJcNvPgDRq7U/w400-h394/April%202016%20Regatta%20pics_1.jpg" width="400" /></a></div><p></p><p>This boat is a very capable family day-sailer, able to carry mom, dad and a few kids together.

ballast keel loads are carried by laminated timber floors, which are beams that
cross the bottom of the boat and pass through the centreline girder. The floor
that aligns with the chainplate semi-bulkhead is being laminated in place against
the backbone and stringers, from which it receives its shape. A host of clamps
is needed to coax the layers of laminations into the required shape and squeeze
excess glue out of multiple joints. The laminating is best done in stages
because gluing all layers at once requires a lot of clamping pressure, which distorts
the stringers outward, slightly flattening the shape of the floor from the
desired curve. The post at left in the photo is a temporary support to hold the
backbone at the correct height while the floors are being laminated.</span></span></span></div><div><span lang="EN-ZA" style="line-height: 107%;"><span style="font-family: arial;"><span lang="EN-ZA" style="line-height: 107%;"><br /></span></span></span></div><div><span lang="EN-ZA" style="line-height: 107%;"><span style="font-family: arial;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhG1ZrNv_M2buzLGaZoXP-DYWd2Bb5gQVGnNhuEKsQGoV-LR3fKsQ3uxT-zACyqR22QRX12nuz6WNtUKzAOLglU6vUvuFfPhHfdqtyx3Uwkb0pNifepcYfhj7okkJVnntv4d3UnknIthSeGMtLdaIKAf3cHRiPqoz8NfOTDiQ1GaYJlyH-tEYkDsR0VoS4/s4624/Didi%20120%20Photo%2012.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3468" data-original-width="4624" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhG1ZrNv_M2buzLGaZoXP-DYWd2Bb5gQVGnNhuEKsQGoV-LR3fKsQ3uxT-zACyqR22QRX12nuz6WNtUKzAOLglU6vUvuFfPhHfdqtyx3Uwkb0pNifepcYfhj7okkJVnntv4d3UnknIthSeGMtLdaIKAf3cHRiPqoz8NfOTDiQ1GaYJlyH-tEYkDsR0VoS4/w400-h300/Didi%20120%20Photo%2012.jpg" width="400" /></a></div><br /></span><p class="MsoNormal"><u><span lang="EN-ZA"><span style="font-family: arial;">Photo 13.</span></span></u><span lang="EN-ZA"><span style="font-family: arial;"> The
floors are in various stages of lamination and shaping. For the shorter floors,
David chose to laminate a few layers on the hull longitudinals to lock in the
basic shape, then to add layers as needed to build to the correct dimensions
and to fine-tune the shape to an accurate fit against the longitudinals. The
floors all taper in thickness towards the ends, so laminating is done with
progressively shorter lengths of timber, then a belt sander is used to smooth
them to the final shape. The hardwood shoe that will form the base on the
outside of the hull for the ballast keel can be seen at the top of the photo.</span><o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-ZA"></span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAeelICPBGzpZ2AjchoJG_iejUHHiKE6h2lJ_joUGwxHRGf3AHxZPRZtkK2l9jb03ZgbbGOmO4-7h2ChlA6j7a83qkDWfIZNURdqHkTO1XbnRPACDj_iwZ5827oT6s5Smmwk_FcILcRuwJ0GS4Ma77Kbx7sJ1B32549DfCi71ClUyz4LG8BIJGyRMZ7AE/s2364/Didi%20120%20Photo%2013.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1773" data-original-width="2364" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAeelICPBGzpZ2AjchoJG_iejUHHiKE6h2lJ_joUGwxHRGf3AHxZPRZtkK2l9jb03ZgbbGOmO4-7h2ChlA6j7a83qkDWfIZNURdqHkTO1XbnRPACDj_iwZ5827oT6s5Smmwk_FcILcRuwJ0GS4Ma77Kbx7sJ1B32549DfCi71ClUyz4LG8BIJGyRMZ7AE/w400-h300/Didi%20120%20Photo%2013.jpg" width="400" /></a></div><br /></span><p></p><p class="MsoNormal"><u><span lang="EN-ZA"><span style="font-family: arial;">Photo 14.</span></span></u><span lang="EN-ZA"><span style="font-family: arial;"> The

The floors have been glued in place to the longitudinals and the keel bolt
holes have been drilled. Doublers are being glued to the forward faces of the
floors to compensate for the timber removed in drilling the keel bolt holes. This
doubler has been completed on the floor on the right and is being done to the
other floors, using blocks and wedges to hold them in place while the glue
cures. The floor on the left is the long one that connects with the chainplate
bulkhead and will later be glassed to it. That junction is at the level of the
settee top, which strengthens the junction as well. The settees are also
structural, serving as girders to support the ends of the floors. The cleats
that will bond the settee tops and fronts to the bulkheads can be seen on the
two full bulkheads at the sides of the photo and the small semi-bulkhead in the
centre. The tangent stringer can be seen on the other side of the hull, with
the plywood doubler over which the junction between flat and radiused plywood

very low CG, so the large loads applied to the hull require a very solid grid
to distribute them away from the immediate area of the keel root. The floors
and backbone structure do that work, with the floors carrying the transvers
loads and the backbone carrying the longitudinal loads from groundings. He is
starting to fill in the spaces between the longitudinals with timber glued to
the floors. Limber holes will be formed through this timber filling to allow

The centreline girder for this design is very solidly constructed to cope with
the very large loads that potentially result from striking a rock with the toe
of the keel. In this photo the spaces between the floors have been filled solid
with timber, with the grain running fore/aft. The limber holes that can be seen
running through the timber have been lined with ¼ sections of plastic pipe, set

through the bulkheads at the ends of the saloon but is too long to be fed
through them. It has a scarph to allow it to be fitted in two pieces with the

<a href="https://dixdesign.com/didi40cr.htm" target="_blank">Didi 40cr</a>. “Passion XI” is the working name of the prototype of the new design
and is being built by amateur builder David Edmiston alongside his house in the
suburbs of Sydney. We are going to follow his project, from the start through
to completion, In a series of articles or photo essays. Thanks to David for
providing the hi-res photos.</span></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">Although very modern in concept, this
design uses a fairly traditional longitudinal girder backbone structure on
centreline. This provides longitudinal stiffness to carry rig loads and
resistance to grounding damage. It is combined with laminated transverse floors
to carry keel loads and spread them into the rest of the hull. During
construction, these structures, as well as a system of stringers and sheer
clamp, are installed over bulkheads that are pre-cut to measurements and
diagrams provided in the drawings and/or a table of offsets. This forms the
skeleton to which the hull skin is fitted to complete the hull.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">There are aspects of this project that are
particular to the radius chine plywood method used for this design but overall
the basic construction sequence and procedures are similar for most plywood
boat projects. This series of photo-essays may help potential amateur
boatbuilders to figure out whether or not a big boat project might be in their
future, whether or not their skills and resources of time, money and endurance will
see them through.<o:p></o:p></span></span></p><p>

bulkheads are ready for setting up. The cleats for joinery components are
already glued on, ready to receive plywood fronts, tops and shelves. They are
all located by measurements from centreline or waterline drawn onto the
bulkheads. This reduces the time needed to build the interior joinery further
into the project, while increasing the accuracy of setting out that joinery. The
cleats are triangular in section, saving 50% of the weight compared with square
cleats of equal size. Laminated roof beams have been fitted, holding the tops
of the bulkheads securely at the correct widths. The surface has been primed
with white epoxy primer to preserve it against weather during construction in
an outdoor building site. Areas that will be glued or will be cut away later
have been left unprimed. Also without primer are a narrow vertical stripe on
centreline and a horizontal stripe low down on the bulkhead, where the
centreline and design waterline (DWL) have been drawn and are needed for future
reference. At the upper corners of each bulkhead, at the deck edge, large cleats
have been glued on diagonally across the corner for gluing and screwing the
sheer clamp. On these designs the sheer clamp sits diagonally across the corner
to give a clean interior structure in that area and allowing a rounded deck
edge on the outside.</span></p><p class="MsoNormal"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi9V1yj0kcw1UbeQrZ0PVwFDxLyDu7wRk2Iw4y85iLajkgXa5692y5Ba72qCxr-6jUqXmf0DmM_ON2a-UrYxuvNIe8yMU6uvn25AVe30czGENrCSlKkAiFxMf0wxRN4vMduIofAq00CJw0VxxBbwhLNr9_4jOh4_ZkgBzz6uZzRJveaFlP8B6BVcE-_ycM/s4624/Didi%20120%20Photo%202.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3468" data-original-width="4624" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi9V1yj0kcw1UbeQrZ0PVwFDxLyDu7wRk2Iw4y85iLajkgXa5692y5Ba72qCxr-6jUqXmf0DmM_ON2a-UrYxuvNIe8yMU6uvn25AVe30czGENrCSlKkAiFxMf0wxRN4vMduIofAq00CJw0VxxBbwhLNr9_4jOh4_ZkgBzz6uZzRJveaFlP8B6BVcE-_ycM/w400-h300/Didi%20120%20Photo%202.jpg" width="400" /></a></div><span lang="EN-ZA"><p class="MsoNormal"><span style="text-decoration-line: underline;"><span lang="EN-ZA">Photo 3.</span></span><span lang="EN-ZA">

up the bulkheads on the building stocks. Each bulkhead is bolted to two legs,
which are themselves bolted to the rails of the building stocks. They must be
set up vertical, at the correct fore/aft positions, centred and at the correct
height, all within 1mm accuracy. This can be achieved by means of a plumb-bob
hanging from a taut centreline string above the boat for vertical alignment and
a laser level for height. This allows any bulkhead to be checked at any stage
during setup, irrespective of other bulkheads. Alternatively, it can be done
with a laser level that has both horizontal and vertical lines to check level
and centring at the same time. For this method the bulkheads must be set up in
sequence from one end of the boat to the other. The bulkheads must also be
stabilized with bracing to hold them firmly until permanent longitudinal
structure secures them. The fastenings must be bolts or large screws because
they will eventually be carrying the full weight of the completed hull
structure plus any people who may be working on top of the hull.</span></p><p class="MsoNormal"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZGaaKfPW8L9CkrVn8MMN98ier0UJ882KjHhRyzPoj4RjWN-Cb_mmpi0yE7yKA7-JkfoeYtrRf5JH3QjSEqmrefUgp_WCslhMlZrPXDgV6LzUr0XeQ5X6LmbWS3XpwBAG_t6Dh7vnkmrZQYawKSOJZMwxhRXousk8DjHRyt8xNtLw-2-FmJZeGFzzX9Ig/s4624/Didi%20120%20Photo%204.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3468" data-original-width="4624" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZGaaKfPW8L9CkrVn8MMN98ier0UJ882KjHhRyzPoj4RjWN-Cb_mmpi0yE7yKA7-JkfoeYtrRf5JH3QjSEqmrefUgp_WCslhMlZrPXDgV6LzUr0XeQ5X6LmbWS3XpwBAG_t6Dh7vnkmrZQYawKSOJZMwxhRXousk8DjHRyt8xNtLw-2-FmJZeGFzzX9Ig/w400-h300/Didi%20120%20Photo%204.jpg" width="400" /></a></div><span lang="EN-ZA"><p class="MsoNormal"><u style="text-decoration-line: underline;"><span lang="EN-ZA">Photo 5</span></u><span lang="EN-ZA">.

The
backbone is being dry-fitted to check for fit and curvature to where it must
fit against the stem bulkhead. The backbone is too stiff to take the required
curvature in the bow, so a horizontal saw-cut is made through the timber to
allow it to be laminated in place. The large piece of plywood that looks like a
longitudinal bulkhead is a temporary support for the stem bulkhead to hold it
accurately in position. This boat has a plumb bow with the stem formed from a
narrow bulkhead of multiple layers of plywood, with a solid timber nosecone
bonded on later in the build process.</span></p><p class="MsoNormal"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcstOA4aReJi3yUHRYiUbCob_fMbwtvGxk0M4mBFWNARZE5M8V8-wt6yhkNIeWWRTD0NVep7sF128VswNapyZdglE5kdWCodZfVjmsMYP3M2ZV3DMXp5Ip7tPkC283GyDRjgj1oIuViODRRAtgeshpewbGfBiUyZWYmWE9nYRLhgS29l1sNzYarPA63Y8/s4624/Didi%20120%20Photo%207.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3468" data-original-width="4624" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcstOA4aReJi3yUHRYiUbCob_fMbwtvGxk0M4mBFWNARZE5M8V8-wt6yhkNIeWWRTD0NVep7sF128VswNapyZdglE5kdWCodZfVjmsMYP3M2ZV3DMXp5Ip7tPkC283GyDRjgj1oIuViODRRAtgeshpewbGfBiUyZWYmWE9nYRLhgS29l1sNzYarPA63Y8/w400-h300/Didi%20120%20Photo%207.jpg" width="400" /></a></div><span lang="EN-ZA"><p class="MsoNormal"><u style="text-decoration-line: underline;"><span lang="EN-ZA">Photo 8</span></u><span lang="EN-ZA">.

The
chainplates of this design are inboard, i.e. they are bolted to a semi-bulkhead
on each side, not to the hull skin. The loads are best transferred into the
structure if those bulkheads align with the load direction. To do this, the
bulkheads point toward the mast. In this photo David has the bulkhead clamped
to temporary timbers that terminate at the mast support post on the major
bulkhead. This boat has a deck-stepped mast standing on top of a reinforced
bulkhead, which I have found from personal experience with my personal boats to
be the best arrangement for a wooden boat. This places all of the structure
under the mast in compression rather than having the compression loads on a
keel-mounted mast foot attempting to force the backbone structure off the
bulkhead, requiring stainless steel tie-bars to contain the loads.</span></p><p class="MsoNormal"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVzUZs119_3vOLFOayeTjXHUuHbndm2lMteZnOpFAz4Ej2P1X-pkzcC4KvX1QdevMEBaFVI-wySXLs4Bgf4eM6-bxPHQFrWx3GV1WnpBjg-oUk8N4zqy1WCiRqVZ5fKlBBJzeyPo7nOJxhKmr8JD-6h4BpVQJMjy4GgRTCSwf1NEvA9EkygGHH3KAEEHE/s4624/Didi%20120%20Photo%2010.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3468" data-original-width="4624" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVzUZs119_3vOLFOayeTjXHUuHbndm2lMteZnOpFAz4Ej2P1X-pkzcC4KvX1QdevMEBaFVI-wySXLs4Bgf4eM6-bxPHQFrWx3GV1WnpBjg-oUk8N4zqy1WCiRqVZ5fKlBBJzeyPo7nOJxhKmr8JD-6h4BpVQJMjy4GgRTCSwf1NEvA9EkygGHH3KAEEHE/w400-h300/Didi%20120%20Photo%2010.jpg" width="400" /></a></div><span lang="EN-ZA"><p class="MsoNormal"><u style="text-decoration-line: underline;"><span lang="EN-ZA">Photo 11</span></u><span lang="EN-ZA">.

The magazine published its final issue a few months ago, with David's boat half-built. This is the first of a series of posts that will duplicate the articles that were published by AABB and then will follow the rest of the build through to launch. This one describes the development of the <a href="https://dixdesign.com/didi_120.htm" target="_blank">Didi 120</a> from the Didi 38, on which all of our radius chine plywood designs are based.</span></p><p><span style="font-family: arial;">These articles show the boat as drawn for David Edmiston, with deep draft keel and rudder, along with a large racing rig. Alternative options will be available for shallower keel and rudder, as well as a smaller cruising rig.</span></p><p></p><p class="MsoNormal"><b style="mso-bidi-font-weight: normal;"><span lang="EN-ZA" style="font-size: 20pt; line-height: 107%;">Didi 120, Bringing the Didi 38 into 2022</span></b><span class="Heading7Char"><b><span face=""Arial",sans-serif" style="color: black; font-size: 20pt; line-height: 107%; mso-bidi-font-family: "Times New Roman"; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-font-kerning: 14.0pt;"><o:p></o:p></span></b></span></p><p></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">I drew the <a href="https://dixdesign.com/38didi.htm" target="_blank">Didi 38</a> in 1994, a fast light
displacement boat for my own use for trans-ocean racing, with an emphasis on
downwind sailing. It did that successfully and the resulting “Black Cat” has
stood up well to 26 years of ocean sailing. One of the many builders who liked
the building method that I developed for amateur builders was David Edmiston in
Sydney. He wanted to build a variation of the Didi 38 that I had previously
drawn, the <a href="https://dixdesign.com/didi40cr.htm" target="_blank">Didi 40cr</a>. That was basically the <a href="https://dixdesign.com/38didi.htm" target="_blank">Didi 38</a> with longer stern overhang
and extended accommodation for more cruising comfort. But David wanted a bit
more cockpit space, so he commissioned a modification to the stern for more
deck beam aft and a T-shape cockpit, with more flared aft topsides to make this
work. The result was his boat “Passion X”, which he and his crew have raced
with good success in the region.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">Midway through 2021 he started discussing potential
modifications with me to upgrade the performance a bit. He was weighing up the
pros and cons for modifying the keel and rig against building a new boat. After
throwing some thoughts back and forth for possible modifications, he was
leaning toward modifying rather than building. Scheduling to draw a new design for
David was far from my thoughts. In the midst of this, Sydney went into full
pandemic lockdown mode that looked like lasting a long time, which decided
David to take the lockdown opportunity to make good headway with a new boat
project, starting asap. For me that presented a problem to squeeze it in with
other projects on the go already. I started on it while winding down the last
of the Cape Deseada 36 design for another Sydney client. <o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">The <a href="https://dixdesign.com/38didi.htm" target="_blank">Didi 38</a> is a light and fairly slim boat,
in the interests of an easily-driven hull and easy motion at sea. Fast on all
headings in light to moderate breeze and strong reaching/running courses, it falls
off a bit in strong winds to windward. David wants more sail-carrying power for
around-the-cans club racing, so called for more beam as well as a deeper keel,
with lead ballast concentrated in the fabricated steel bulb rather than split
between fin and bulb.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">He thought that the new boat would be near
enough to the shape of “Passion X” that I could cut that design down the
middle, spread the two halves apart 400mm and fill in the missing bit in the
middle, at the same time changing it to a plumb-bow and very short stern
overhang, to maximise waterline length. It sounds doable and that process can
work with physically modifying an existing boat but that is not the way that
boat design works to create a good overall design. It is much less problem to
just start from the beginning and draw a boat that targets desired criteria.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">David ordered material right away, based on
his previous build. He also started preparing the build site, with the new boat
to be assembled on the same building stocks as “Passion X”, alongside his home.
That really turned up the pressure on me, not yet having started to draw the
boat and the builder aching to start. There are design cycles that have to be
worked through and short-circuiting that order of development can generate
problems. David may have found it a bit frustrating as drawings went back and
forth, progressing another step each time toward what he needed before putting
saw to wood for the first time. Scantlings, basic construction detailing and bulkhead
diagrams were needed for work to start but they couldn’t be done prior to many
iterations of hull shape, running hydrostatic numbers and doing structural
calculations. I fed those drawings to him as soon as they had progressed enough
to be of use to him but it was only after many weeks of drawing that I could
see a bit of daylight between my progress in the computer and the progress on the
boat that was taking shape literally on the other side of the world.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">David was very clear about what he wanted
in the new boat. He enjoyed the build process of “Passion X”, so wanted the construction
method and detailing to be the same. The layout works well for him and his crew,
so that basic interior was also to stay, with small changes to make better use
of the wider hull. The deck configuration suits him and his mature crew, so
that was a given as well. From those parameters plus the long waterline,
everything else in the concept came together. The longer waterline gave more
usable interior length, so some rearrangement was done to nicely match the interior
to the rig and ballast keel support structure requirements, as well as the rig
to the underbody to ensure good sailing characteristics.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">In order to get Cat A racing certification
in Australia, the new boat must meet ISO structural requirements. I drew the
Didi 38 to the requirements of American Bureau of Shipping Guide for building
and Classing Offshore Racing Yachts, as applied at the time, so it was going to
be interesting to see how the structures compared when designed to different
scantling rules.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">The ISO scantling rules proved to be
considerably more complicated but, overall, the hull and deck structure came
out quite similar. The exception is in the grid structure that carries the
ballast keel loads and distributes them into the rest of the hull, as well as
the keel bolts that transfer the keel loads into the grid structure. Much of
this is due to the considerably lower CG of the keel, applying larger forces on
the hull structure. But some of it may
be due to tightening of requirements in response to a few boats losing their
keels around the world.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"></span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjLYkLQCUjLBwctcZ4XjQiLPlMwOl7w3Q203HMiG8ug26WW_eEshQ4-AOuK3kka_q1AM48u7UZA_KlQVumBXBo9r9NymhrJKwHl06HlU0Tqud4prw3mZoSr8lVZVamnesuFVbLB9g67BK2YKXToJn7RCKhPpqKkJOBbAQO12yEiWd4la2cp_ejDyt8SSJo/s1376/Didi%20120%20Accom.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="832" data-original-width="1376" height="241" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjLYkLQCUjLBwctcZ4XjQiLPlMwOl7w3Q203HMiG8ug26WW_eEshQ4-AOuK3kka_q1AM48u7UZA_KlQVumBXBo9r9NymhrJKwHl06HlU0Tqud4prw3mZoSr8lVZVamnesuFVbLB9g67BK2YKXToJn7RCKhPpqKkJOBbAQO12yEiWd4la2cp_ejDyt8SSJo/w400-h241/Didi%20120%20Accom.jpg" width="400" /></a></div><span style="font-family: arial;"><p class="MsoNormal">The keel of the <a href="https://dixdesign.com/38didi.htm" target="_blank">Didi 38/40</a> is relatively
slim, with low frontal area. That is great for downwind racing and other
situations that don’t require lots of lift. The bulb has a delta form, with
hard bottom edge that works well on flat water but struggles a bit when pushing
hard to windward in lumpy water. The new boat is more of a round-the cans
racer, with more emphasis on windward performance. Her keel is thicker, with a
foil section that has better lift/drag characteristics. The extra thickness and
redesigned construction makes a stiffer keel that is better able to carry the
increased ballast loadings. The bulb, also delta-form, is larger to accommodate
the increased ballast volume, with modified toe shape to improve flow in lumpy
water, also softening the shock-loading that accompanies an accidental grounding.
Both keels are flared at the root to reduce bolt loadings.</p></span><p></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">The rudder is a deeper and slightly slimmer
spade, with a more forgiving NACA 000 foil section and options of either tiller
or wheel steering on the same basic configuration. My preference on a boat of
this size and type is a tiller for fast and intuitive response but I think that
David will make his decision further into the build. The shaft is exposed
inside the boat to allow fitting of a quadrant for wheel steering as well as a
short tiller for electronic autopilot.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-ZA"></span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhM5qedXO2rCvne4EK7TP33RtF9L1mhV_DBkGJbbG9P2cpbsc5zu2SLmCrSyDW2Fkud78AvnuHJPG6aacea_D6soGfSgSy7cWIIyf_znUIqgO03on8fsSEJphRL6zka0ZFgJxo0DxoXndGqBkJ61c2lpylPE9nNROHBL9bQvYfFF_fokDdpvmoE7U03Q3w/s672/Didi%20120%20Rig.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="672" data-original-width="615" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhM5qedXO2rCvne4EK7TP33RtF9L1mhV_DBkGJbbG9P2cpbsc5zu2SLmCrSyDW2Fkud78AvnuHJPG6aacea_D6soGfSgSy7cWIIyf_znUIqgO03on8fsSEJphRL6zka0ZFgJxo0DxoXndGqBkJ61c2lpylPE9nNROHBL9bQvYfFF_fokDdpvmoE7U03Q3w/w366-h400/Didi%20120%20Rig.jpg" width="366" /></a></div><span style="font-family: arial;"><p class="MsoNormal">The rig is configured to make it easy to
sail and versatile for around the cans and distance racing. With less emphasis
on overlapping headsails, it has higher-aspect headsails and proportionally
larger mainsail. The new boat has more displacement and wetted surface, so it
has more sail area to compensate for those changes. It has an on-deck
retractable sprit for asymmetricals as well as a conventional pole for
symmetrical spinnakers. The mast is supported by double swept-spreaders, with
the V1 wires close to the rail and the D1 wire inboard. The broad staying base
gives better support to the mast, to better handle the loads from the much
greater righting moment, also giving more scope for headsails with moderate
overlap to sheet through the gap and easing crew movement past the shrouds. It
has a babystay to improve stability of the deck-stepped mast, as well as an
inner forestay for a staysail or heavy-weather jib. As with the <a href="https://dixdesign.com/38didi.htm" target="_blank">Didi 38</a> and all
of its derivatives, the mast stands on top of a major bulkhead that is

X” he replaced the bridgedeck-mounted mainsheet traveller of the <a href="https://dixdesign.com/38didi.htm" target="_blank">Didi 38/40</a>
design with a 4:1 tackle on a bridle on the cabin roof, with the tail led
forward along the boom to the base of the mast. I have duplicated that system
on the Didi 120 deck layout but an alternative with traveller mounted on the
cabin sole will also be on the final drawings. From the mast base, all halliards,
reefing lines etc. and the mainsheet go back to banks of jammers and a pair of
winches.</p></span><p></p><p class="MsoNormal"><span lang="EN-ZA"><span style="font-family: arial;">Along with the cleaner cockpit, the bridgedeck

extensive Velocity Prediction Program evaluation I concluded that to get the performance
I wanted we needed a heavier, deeper keel, a longer waterline and a taller rig

the logical option.<o:p></o:p></i></span></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="mso-ansi-language: EN-GB;"><span style="color: #990000; font-family: arial;"><i>On the
specifics I wanted the longest waterline reasonable on a 12 metre yacht, high
form stability from a 400 mm width increase and good windward heavy air sailing
characteristics from a deeper heavier bulb. By choosing a taller rig we could
eliminate overlapping genoas for the same foresail area and gain some area in
the taller mainsail.<o:p></o:p></i></span></span></p>

construction details and the general arrangement I was very satisfied with my
current Didi 40 Cr2 and wanted only to replicate what we had but wider side
decks and a wider bow. After Dudley accepted the design commission, he found
ways to use the extra 400 mm width for some very pleasing incremental
improvements in the accommodation and Dudley kept introducing new improvements

Her purpose is adventure cruising in the desolate wilderness waters of Eastern British Columbia. These waters are mostly sheltered by the many islands but can be wild and treacherous, with strong tides and unchartered rocks. They are also known for the massive logs that litter the shores, having escaped from the logging companies. Those that have not yet found a beach are a danger to boaters, particularly when they are nearly waterlogged and floating vertical, with only a few inches of one end above the surface and very difficult to see. Ready to punch a hole in a hull right at waterline, they are known as deadheads.</p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEhNNv4k_gEpKorY7glbp8WdqwPOzoIGwn6GQyah0MHn6HY3Ne0rskVCW7_7f-ak661FAUZlmA22gQCmIFy0mW_S-qKFgkiY4DoyT6Dj9q8_nZIa0jOysLBRig7T4szMI8qqydlOu1qpqu_xgrprSjGw8UsnTchm40eaTkjBiXTfUWeiu3Bj18VQVDol=s1012" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="771" data-original-width="1012" height="305" src="https://blogger.googleusercontent.com/img/a/AVvXsEhNNv4k_gEpKorY7glbp8WdqwPOzoIGwn6GQyah0MHn6HY3Ne0rskVCW7_7f-ak661FAUZlmA22gQCmIFy0mW_S-qKFgkiY4DoyT6Dj9q8_nZIa0jOysLBRig7T4szMI8qqydlOu1qpqu_xgrprSjGw8UsnTchm40eaTkjBiXTfUWeiu3Bj18VQVDol=w400-h305" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Gaff schooner sail plan</td></tr></tbody></table>Aluminium was chosen for this boat as the best material to survive potential collisions with deadheads or rocks when far from any rescue services. As an added safety feature, most of the space between hull and deck is foam-filled for flotation.<p>The hull is the same family as my lapstrake plywood Cape series of designs and we decided to keep the lapstrake format, for the character that it adds to a classic hull form. That meant that between the builders and myself we had to work out construction details that would look good, without excessive welding that aggravates heat distortion. Built by John Dearden of Gibsons BC, helped by owner Tom McPherson and his dad, they did a beautiful job of the build.</p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEihZ_JBOC5EAOdEHQGR5FJK3UB7FHYlp1MGaGzXeCS07b2qb2QCRGYM4YpdZkyEt9mctxdivhGgK9jOEkE8imOqHGUzyke1nrGf4Cqsdf2qapUlEJEyRVTdpqyLOT6Fog0f1dfiH6ucLLDeRzDlm5TCT06alXZSTea1gVBV9e4PJbx2deCRUxXZicYn=s1057" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="595" data-original-width="1057" height="225" src="https://blogger.googleusercontent.com/img/a/AVvXsEihZ_JBOC5EAOdEHQGR5FJK3UB7FHYlp1MGaGzXeCS07b2qb2QCRGYM4YpdZkyEt9mctxdivhGgK9jOEkE8imOqHGUzyke1nrGf4Cqsdf2qapUlEJEyRVTdpqyLOT6Fog0f1dfiH6ucLLDeRzDlm5TCT06alXZSTea1gVBV9e4PJbx2deCRUxXZicYn=w400-h225" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Aluminium Fast Eddy hull on turn-over day.</td></tr></tbody></table>The work for this boat after launch is taking charters into those wilderness waters for adventure camp/cruising, nature photography touring, youth training, corporate team building and similar activities far from comfortable civilization. It is work that needs to be done with absolute minimum disruption of nature and zero destruction of the places that they visit. To that end, this is a sailing and rowing boat, with a backup outboard motor stowed in a locker and only used as a last resort.<div><br /></div><div>The cockpit takes up most of the length, with four rowing positions on each side. Under the seats are personal storage lockers and between them are insulated food lockers. Insert panels convert the individual seats to long sleeping platforms. Forward of the cockpit is a bow cabin with enclosed heads, galley and V-berths.</div><div><br /></div><div>The sailing rig is gaff schooner, basically a cutter rig forward, with the normal boom replaced by a wishbone boom and stepped in a tabernacle to fold aft. Another identical mast and sail, without headsails, stands aft. This one is also stepped in a tabernacle but folds forward.

It is very slim, with extremely fine bow. This makes it easily-driven for rowing and for sailing in light breezes. Sailing reports are that it is very quick as long as there is some breeze. She competed in the R2AK event in 2019, averaging 3.3 knots in mostly rowing conditions but recorded 13 knots in the stronger breeze of the finishing stretch.<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEh5opsgUVA0SVaqtLvrZpo71RbwHLzkFxMfPvZ44YExLPY4W7S479Weo6Ow5bVbXR8lyBg7AQo9k-aWNozaavNP-xtEkHboaE03FRbIrfqKErD7_7aOXEbsT_fTpwh6NoBp8jiuTi_B4Dw149aCMa5mov0MLN7fOatuhnF_de1QsbGnneKJGKgXReS4=s960" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="720" data-original-width="960" height="300" src="https://blogger.googleusercontent.com/img/a/AVvXsEh5opsgUVA0SVaqtLvrZpo71RbwHLzkFxMfPvZ44YExLPY4W7S479Weo6Ow5bVbXR8lyBg7AQo9k-aWNozaavNP-xtEkHboaE03FRbIrfqKErD7_7aOXEbsT_fTpwh6NoBp8jiuTi_B4Dw149aCMa5mov0MLN7fOatuhnF_de1QsbGnneKJGKgXReS4=w400-h300" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Launch day.</td></tr></tbody></table>To see this and our other designs, go to our <a href="https://dixdesign.com/" target="_blank">main website</a> or our <a href="https://dixdesign.com/mobile" target="_blank">mobile website</a>.<br /><div><br /><div><br /></div><div><p><br /></p></div></div>Dudley Dixhttp://www.blogger.com/profile/10463988486568081821noreply@blogger.com6tag:blogger.com,1999:blog-8574088453848301473.post-37487234517250156542021-12-17T23:07:00.000-05:002021-12-17T23:07:21.699-05:00Cape Deseada 36TC, Lapstrake Plywood Family Cruiser<p> Our Cape range of lapstrake cruiser designs started with the <a href="https://dixdesign.com/inspir19.htm" target="_blank">Cape Cutter 19</a> about 20 years ago. Commissions came in periodically, always pushing upward from what we had before. They grew to the <a href="https://dixdesign.com.ch21.htm" target="_blank">Cape Henry 21</a>, <a href="https://dixdesign.com/cm25.htm">Cape May 25</a>, <a href="https://dixdesign.com/cm25.htm" target="_blank">Cape Charles 32</a> and now the <a href="https://dixdesign.com/cd36tc.htm" target="_blank">Cape Deseada 36TC</a>.</p><p>So, why is this one titled a "TC" and not the others? This one has a trunk cabin deck configuration, whereas all of the others have a raised sheer and flush deck. It was commissioned by two amateur builders on different continents but both wanting similar features in a bigger boat than we could offer with the Cape Charles 32. Overall they wanted a larger version of the 32 but with trunk cabin and side decks to give more secure footing when working on deck in rough water.</p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEiLmf8t0_MmArtQviBINUZYAyEXdz0k_5bG42Y3wJXOmxkAPAQ0VEo5jXDkaZZqo1n7gH5NPGXO21uJvsb5EtYc8U3fGb_MHCB9gkwvQK1GmQa26yCRJq5WXtKx3KxxB33HfmX6N7ydvYBZDr7aof3TbfPdqQdygYwPhjX_e0Mfl4pe3LpbCXHfqyLN=s787" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="787" data-original-width="657" height="400" src="https://blogger.googleusercontent.com/img/a/AVvXsEiLmf8t0_MmArtQviBINUZYAyEXdz0k_5bG42Y3wJXOmxkAPAQ0VEo5jXDkaZZqo1n7gH5NPGXO21uJvsb5EtYc8U3fGb_MHCB9gkwvQK1GmQa26yCRJq5WXtKx3KxxB33HfmX6N7ydvYBZDr7aof3TbfPdqQdygYwPhjX_e0Mfl4pe3LpbCXHfqyLN=w334-h400" width="334" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Cape Deseada 36 with Marconi rig.</td></tr></tbody></table>This initial version has a Marconi rig with squaretop mainsail, a powerful and efficient rig for performance with a small crew. The working sails are mainsail and an inboard jib tacked to the stemhead on a furler. A Genoa, code 0 and asymmetrical spinnaker can be set flying on top-down furlers from the end of the bowsprit.

The main benefit is that all berths are more than 2m in length, the aft double being 2.3m long. The offset V-berth in the forecabin has a chain locker under the head of the port berth, fed by an anchor windlass on the sunken foredeck. The chain pipe is a reinforced rubber hose to stop the chain from rattling crew out of their sleep.<div><br /></div><div>The layout plan might be described as boring but it offers safety at sea rather than party space for lying against a marina dock. Everywhere that you go inside this boat you will have things to grab onto or to lean against when needed on bouncy water. </div><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEhYzdHi-oEQ2F4vKkk50913wxaR4COgC3aETWotMw8qsOUeRhPJow1dFZH6OgvplNoVJXXvnOe9uWU158ABmECvJxkl41W5VxlLWEL7npNphcZPhwdGCAa2CHBxtYmF3POkXHX2EM2vYj7tiYgZ9em44T_JYRNqdkeHhl2j0O6IdMclUN3oKZeDCEve=s1385" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="787" data-original-width="1385" height="228" src="https://blogger.googleusercontent.com/img/a/AVvXsEhYzdHi-oEQ2F4vKkk50913wxaR4COgC3aETWotMw8qsOUeRhPJow1dFZH6OgvplNoVJXXvnOe9uWU158ABmECvJxkl41W5VxlLWEL7npNphcZPhwdGCAa2CHBxtYmF3POkXHX2EM2vYj7tiYgZ9em44T_JYRNqdkeHhl2j0O6IdMclUN3oKZeDCEve=w400-h228" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Deck plan and profile of the Cape Deseada 36TC</td></tr></tbody></table>The hull has a long waterline and fine bow, for easy motion and performance in a wide range of conditions. The lapstrake hull is skinned with plywood over stringers and bulkheads. Construction is within the capabilities of a reasonably skilled amateur, it doesn't need professional boatwright skills. The ballast is bolted through deadwood and the rudder is transom-hung for simplicity. The skin in the ballast area is glass-reinforced inside- and out, with the glass wrapping over the plywood internal structure of backbone and floors as well.<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEirJcfca2vQJdCeq_IQxi8lsCxGguS1brcNN8x7ry1OuHT1T2cYYy6aDuA0Fz96crcWYn-e8ldpV9EMXqCN1xegqD6EnwL3iOoIeoFfM03W3KTk_7mF8ECvtnS9kKMJlMIHQGfleVGCfAk1YzmVyAIciUgSEhXZefJuehT8vLiC_L395QQM-aszNAB7=s986" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="770" data-original-width="986" height="313" src="https://blogger.googleusercontent.com/img/a/AVvXsEirJcfca2vQJdCeq_IQxi8lsCxGguS1brcNN8x7ry1OuHT1T2cYYy6aDuA0Fz96crcWYn-e8ldpV9EMXqCN1xegqD6EnwL3iOoIeoFfM03W3KTk_7mF8ECvtnS9kKMJlMIHQGfleVGCfAk1YzmVyAIciUgSEhXZefJuehT8vLiC_L395QQM-aszNAB7=w400-h313" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Midship section of Cape Deseada 36TC</td></tr></tbody></table>Read more about this and our other designs on our <a href="https://dixdesign.com/" target="_blank">main website</a> or our <a href="https://dixdesign.com/mobile" target="_blank">mobile website</a>.<br /><div><br /><div><br /></div><div><div><br /></div></div></div>Dudley Dixhttp://www.blogger.com/profile/10463988486568081821noreply@blogger.com1tag:blogger.com,1999:blog-8574088453848301473.post-46803869658760927322021-12-01T22:28:00.000-05:002021-12-01T22:28:57.910-05:00CC19 Dayboat, Family Daysailer & Camp-Cruiser<p> I designed the <a href="https://dixdesign.com/inspir19.htm" target="_blank">Cape Cutter 19</a> in 2000, as a little GRP production trailer-sailer for <a href="https://capercutter19.com" target="_blank">Cape Cutter Yachts</a>. A few years later I added a plywood version for amateur builders, now with nearly 90 plywood boats in 28 countries. Since then I have been asked a few times for an open day-sailer version. Here it is, the <a href="https://dixdesign.com/CC19Dayboat.htm" target="_blank">CC19 Dayboat</a>.</p><p>This is more than a basic day-sailer though, the cockpit is proportioned for up to 6 people to sleep comfortably on airbeds on the cockpit sole and seats, as a camp-cruiser. That space also means that a family of 6 or more can all sail together for day-sailing and picnic cruises rather than taking turns.</p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiJtQi0xSAxJLVP-TabMCau8diKF41pF0HLbBOnMN8zJGTrtjK8TisC1c-vx9oT-Zve9UXVQedkSi_8pcrjrKRyZB3kOMzwwTOTiGsVcGmnViqRnu2BjiXKHhaaKqflAIL0MYcQ8UNBDr0/s782/CC19Dayboat+rig.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="782" data-original-width="717" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiJtQi0xSAxJLVP-TabMCau8diKF41pF0HLbBOnMN8zJGTrtjK8TisC1c-vx9oT-Zve9UXVQedkSi_8pcrjrKRyZB3kOMzwwTOTiGsVcGmnViqRnu2BjiXKHhaaKqflAIL0MYcQ8UNBDr0/w366-h400/CC19Dayboat+rig.jpg" width="366" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Gaff rig of CC19 Dayboat</td></tr></tbody></table>The Cape Cutter 19 has a great reputation for surprising speed in light to moderate breeze and seaworthiness in strong winds and big seas. Those same characteristics are passed on to this version. In line with that seaworthiness, the cockpit is above waterline and self-draining, with any water from a boarding wave exiting via two routes, through the engine well and the centreboard casing. The 16 independent buoyancy compartments under the cockpit and seating further increase the safety.<div><br /><div><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh086zgMMx7JUM6FQnV1bRG0MN2a4JLpkNWZsHIsQQtPhjMGO_RZpki9DrhtNMwbZh7iUu1kGCojFQJDtU8tCPPlbJkj2ILz9axfB-DbCbpJpja52ECUN5YFQtLzj9co-nnXIlg8ltUqXU/s963/CC19Dayboat+deck.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="763" data-original-width="963" height="318" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh086zgMMx7JUM6FQnV1bRG0MN2a4JLpkNWZsHIsQQtPhjMGO_RZpki9DrhtNMwbZh7iUu1kGCojFQJDtU8tCPPlbJkj2ILz9axfB-DbCbpJpja52ECUN5YFQtLzj9co-nnXIlg8ltUqXU/w400-h318/CC19Dayboat+deck.jpg" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Deck & cockpit layout </td></tr></tbody></table><br /> The forward seats fold down to add floor space when needed. Under the foredeck is a small lockable cuddy for safe and dry storage. At the other end, the outboard engine sits in a well, with a dam around it to contain oil spills. The motor is covered by a hinged hatch over the top and a door in front. The motor sits just ahead of the balanced transom-hung rudder, for quick helm response when motoring in tight spaces.</div><div><br /></div><div>The sail plan is the same as the Cape Cutter 19 and should be sailed the same way. There are three headsails, Genoa, Yankee and staysail/jib. The Genoa should be used with the main in light to moderate breeze for best speed. For those who prefer a true cutter rig, use the Yankee along with the staysail and mainsail. For strong winds use the staysail as a working jib along with the mainsail, reefed as needed for the wind strength.</div><div><br /></div><div>The mast is stepped in a tabernacle for easy raising/lowering and the bowsprit folds aft. The main forestay goes to the stemhead, with the staysail either hanked or on a furler. The Genoa or Yankee can be on a soft furler or top-down furler.</div><div><br /></div><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjg70adAVMmTUCG2U1X3cjT4z_1oWiWdvcKTXZ-7LLTStU4_o8g_22XGXMPGcba4XpZPntxXtUdMX8lH6ySKQAjobshU4RodRlrKr1GIGjQzgoIbS_x1JtV6jfDaJHh4a81VoMjV6THT2g/s1308/CC19Dayboat+section.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="677" data-original-width="1308" height="208" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjg70adAVMmTUCG2U1X3cjT4z_1oWiWdvcKTXZ-7LLTStU4_o8g_22XGXMPGcba4XpZPntxXtUdMX8lH6ySKQAjobshU4RodRlrKr1GIGjQzgoIbS_x1JtV6jfDaJHh4a81VoMjV6THT2g/w400-h208/CC19Dayboat+section.jpg" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Section through centreboard casing</td></tr></tbody></table>The centreboard is glass-sheathed plywood, ballasted with a lead insert. Primary ballast is internal, in the bilge and glassed over to secure it in place. My client for this design chose to keep the solid ballast of the Cape Cutter 19 rather than change to less effective water ballast.</div><div><br /></div><div>This boat can be built from plans, which include full-size Mylar patterns of the bulkheads, backbone and transom.

My client was Paul Slade of <a href="https://dixdesign.com/sladerowing.htm" target="_blank">Slade Rowing</a>, operating in Johannesburg, South Africa. The result was the Vision Lightweight Single and the Vision Heavyweight Single rowing shells. The boats were very modern in concept, nothing like any others on the market worldwide at the time and proved to be fast. The high-prismatic hulls with plumb bow and small V-shaped transom have low pitching characteristics, are easily-driven and track well. The company failed financially due to distance from the main market and insufficient funding.</p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjZ2W2DKcTsoGT1lAY7Vj4ayFui-ARVckU_45SnijcLf7PwQyyd6SGeZyOgOB67L-ats4kiEcGoxrKxv3wG_lfd0Tlkw3wvG_H3XpxAdRXByvad_pvRE3xHIR_5sZBWLDhyphenhyphen-4vY6tD-S64/s1600/Light+single+UK+3.JPG" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjZ2W2DKcTsoGT1lAY7Vj4ayFui-ARVckU_45SnijcLf7PwQyyd6SGeZyOgOB67L-ats4kiEcGoxrKxv3wG_lfd0Tlkw3wvG_H3XpxAdRXByvad_pvRE3xHIR_5sZBWLDhyphenhyphen-4vY6tD-S64/w400-h300/Light+single+UK+3.JPG" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Vision Lightweight Single on show in Ireland</td></tr></tbody></table><div class="separator" style="clear: both; text-align: left;">Over the years since Slade Rowing closed down I was requested many times for plans to build these boats as one-off projects.

So it is with the beautifully-executed build of the 27ft sportfisherman of Kevin Agee's. We slipped her quietly into the water last month to mark flotation ahead of painting her anti-fouling bottom paint. As it was she floated perfectly as expected but it is always nice to get confirmation when that can be done.<br />
<br />
On that first wetting the motor was started but no sea trials. She came back out of the water on her trailer and went home for painting.<br />

Two weeks later she went back into the water with her bottom painted, this time to run in the motor and do some early trials.<br />
<br />
The 300hp Suzuki 4-stroke motor is very smooth and suits her well. The water in the river was smooth but it is all no-wake zone, so we idled along the channel. Once out into the mouth of the river the water lumped up quickly from the strong winds in the bay. While running in the motor she did 18 knots with the maximum 3000rpm permitted. After her running in was completed Kevin took the motor up to 4000rpm and 26 knots. With short 1-2ft wind chop she has a soft and dry ride, upwind and downwind.<br />
<br />
Last weekend we went fishing, with the opportunity for more trials on flat water. She shows predictable handling, cruises comfortably at 25+ knots and tops out at close to 40 knots.<br />

A kit is currently in development for the new Dix 430 catamaran. The kits are very comprehensive and can be customized to each customer's needs, from basic bulkhead kits through to inclusion of whatever equipment and materials the particular builder would like to be delivered in the shipping container with the pre-cut plywood and other timber.<br />
<br />
I have written about the <a href="http://exocetus.net/" target="_blank">Exocetus Marine</a> kits in earlier posts on this blog, from when development first started in 2012. They have come a long way since then, under the expert hand of owner Kevin Bream.<br />

<a href="http://exocetus.net/" target="_blank">Exocetus Marine</a> is now expanding their range in a new direction. This harkens back to my origins in radius chine plywood designs with my <a href="https://dixdesign.com/38didi.htm" target="_blank">Didi 38</a> prototype "Black Cat", which has spawned a large and expanding range of designs from 15ft to 55ft, spanning both monohulls and multihulls. The Didi 38 design itself expanded to the <a href="https://dixdesign.com/didi40cr.htm" target="_blank">Didi 40cr</a> and, most recently, the <a href="https://dixdesign.com/didi40cr.htm" target="_blank">Didi 40cr2</a>.

As with their catamaran kits, Exocetus is developing a very comprehensive kit for this first expedition into monohulls. In doing so they have transformed my CAD drawings into a complete 3D model before extracting the components for cutting by CNC then testing for accuracy of build. In doing this they are building the boat as well, enabling preparation of complete building instructions to guide those who will follow to build the Didi 40cr2 for themselves.<br />

Since then a lot has happened. If you think that you have had it tough on land through the COVID-19 pandemic, you may change your mind after hearing Barry's story.<br />
<br />
The photos below show some of the incredible scenery that they visited. Barry was not alone, he had two crew with him. Together they visited places and had experiences that very few people in the world will ever appreciate. It takes much hard work and dedication to get to these places and very few boats manage to receive permits to even go there.<br />
<br />
This time the weather was much more mild than the previous year. But it is a very dangerous place and the weather can turn very fast, changing an apparently safe anchorage into a deathtrap. That is when an able boat and capable crew combine to bring all involved back to safety. Always being aware of every aspect of the surroundings, i.e. terrain both above and below water, ice and weather is imperative to certainty of completing the cruise plans and getting home again.<br />
<br />
Even the most carefully laid plans can go wrong, for totally unexpected reasons. It was on the voyage back from Antarctica that exactly that unexpected situation dumped itself on, not only "Spailpin" and her crew, but on the entire world. They sailed from Antarctica to Tierra del Fuego, then to South Georgia. From there the next stop was to be Tristan da Cunha, approx. 1450 nautical miles away. They arrived there to find that COVID-19 was hammering the world and everything was shutting down. That included Tristan da Cunha and they were not permitted to land, despite having been at sea in the most extreme of self-quarantine conditions for a month, with zero chance of having contracted the virus.<br />
<br />
So, they headed back out to sea, target Cape Town, South Africa, another 1500 miles away. But two days after leaving Tristan South Africa closed down, shutting off that option. They changed course for Jamestown on the island of St Helena. After being in the Southern Ocean for more than a year this leg can be a bit of a doddle through or around the South Atlantic High but 1300 more miles to get to a destination that they did not want.<br />
<br />
They arrived off Jamestown to another closed port. One of the crew needed to return to Cape Town and was allowed to go ashore on St Helena through diplomatic intervention. He was to fly to Cape Town while "Spailpin" voyaged further, next stop Georgetown, Ascension Island. This was to be a relatively short hop of 700 miles but ended the same way. Barry was able to go get fuel before they coninued on their way, now headed for USVI in the Caribbean.<br />
<br />
By then Barry was urgently needing to get back to work, so flew off to take care of that while his crew sailed "Spailpin" from the Caribbean to Chesapeake Bay, where she is now in Annapolis, MD.<br />

Barry needed to move up to a larger boat for his future voyaging and contacted me before this recent voyage to ask if I knew of a suitable candidate built to one of my designs. No suitable boat was available but he has found a boat from another designer and bought it. That brings "Spailpin onto the market at a very attractive price for a quick sale. There can be no doubt that this boat is well-proven for voyaging to the harshest oceans on our planet. If you are interested in buying her, <a href="https://dixdesign.com/email.htm" target="_blank">contact me by email</a> so that I can put you in contact with Barry.<br />

I didn't realise that it is more than two months since my last post. Time flies when you are having fun, or busy. I am working on a 71ft aluminium cruiser, with the detailing taking a lot of time.<br />
<br />
Our lives are being disrupted by the COVID-19 virus that is bringing the world to a standstill. Here in Virginia we are not yet in a lock-down situation but that is probably in our future before long. For now we are social distancing, chatting to neighbours at a distance and keeping contact with faraway family by Skype and WhatsApp.<br />
<br />
I work from home, with my wife Dehlia as my only co-worker. We are able to work on as before despite the restrictions.<br />
<br />
Many people are taking a break from their normal work, some enforced by authorities and others by choice, to ensure isolation from potential infection sources. We all hope that the situation will return to normal within a few weeks but that looks more and more unlikely.<br />
<br />
When stuck at home, staying productive helps to fill the days and lift the spirits. A big enough project can involve most or all of the family, racking up quality time and keeping minds off wanting to be elsewhere. Making something worthwhile with our own hands is very satisfying and can provide the balance needed to keep us sane, reducing cabin fever.<br />
<br />
If that something worthwhile that you build is a boat then you will have a new family toy when summer comes or when we can get to the water again. Some of my happiest times as a child were those spent sailing or fishing with my dad. As a teenager those prized memories were made on the water, rowing our family dinghies and, especially, sailing my own boat.<br />
<br />
If you are already building one of our boats then nothing changes. Our personal <a href="https://dixdesign.com/backup.htm" target="_blank">backup</a>, included in the <a href="https://dixdesign.com/priceabr.htm" target="_blank">price of our plans</a>, continues as usual and we can advise when needed. If you are considering building, we will do all that we can to help you. We have offered study packs and dinghy plans for delivery as PDF files by email as an alternative to traditional paper prints. We will now expand this to include construction plans, under our normal <a href="https://dixdesign.com/FAQorder.htm" target="_blank">terms of sale</a>.<br />
<br />
In the past most customers have been happy with paper plans sent by first class mail, transported by the airlines and delivered by the postal services in the destination country. There have been massive cutbacks in air travel, so most of the aircraft that would have carried the packages to faraway places are grounded. With so few planes, airmail services are under pressure and have slowed considerably, aggravated by slower delivery in the destination country due to restrictions in movement of people. The alternative of courier service speeds up delivery but is costly. Receiving the plans as PDF files may be a viable option for some builders.<br />
<br />
PDF files do have drawbacks, related to the size of the drawings that you will be using. Most of them were drawn to A1 size of 491x841mm (23.4x33.1"). These are way too big to print on a standard A4 or letter size printer but you can view them on-screen and zoom in to see details. You may be able to print sections of a drawing or your printer may have a nesting feature to print in sections for taping together into a single sheet. The best option is to take the files to a print shop for printing on a large format inkjet printer.<br />
<br />
Here are samples of drawings to show what you will receive for two different types of designs. Click on the links to see them online, which will have limited clarity. Download into your computer and view in a PDF Reader program. Zoom in to appreciate the greater clarity that is available.<br />

Some of our designs include full-size patterns, which we normally print on 36" Mylar roll media. Some of them are as long as 16ft, totally impractical to print in small sections with an expectation of accuracy. These must be printed on a wide format printer. You can print on paper instead of Mylar if you store them in a sealed plastic sleeve and use them within a few weeks. Delaying their use risks dimensional change due to variations in humidity.<br />

It was sent to me by Gavin Muller, who was the youngest in our 5-man crew. He took it on the last night of our race, as we were sailing between our Brazilian landfall of Cabo Frio and the finish line off Copacabana Beach, Rio de Janeiro.<br />

The Cape to Rio Race is 3500 miles of tradewind ocean racing, starting in Cape Town and finishing in Rio de Janeiro. A race like this breeds friendships that last a lifetime. Most of us were good friends before the race and the three weeks in close quarters in the middle of nowhere, in company of seabirds and the occasional fish or whale, cemented those friendships forever. Gavin was the odd-man-out at the start of the race, being much younger than the rest of us, but he too became a friend for life.<br />

Adrian Pearson (RIP) was my partner in "Black Cat". Brian Cole introduced us while I was building our boat for the race, bringing him in as crew. Later he joined me to co-finance the project.<br />
<br />
Brian Cole (RIP) was the oldest in our crew, at 60. He was a director of North Sails Cape Town and a regular on the crew of my previous boat, "Concept Won". He joined us on this race as navigator for his first and only ocean-crossing voyage. His wife, Marion, was co-skipper with Judy Provoyeur of the all-lady crew of the Schumacher 41 "Kelly Girl", our closest handicap competition in the race. On handicap, they had to reach Rio more than 20 minutes ahead of "Black Cat" to beat us.<br />
<br />
Sean Collins was a client many years ago for a rig redesign on his cruiser. He became a friend, sailing with me for many, many miles on "Concept Won". We raced together uncountable times in fully-crewed and double-handed races around the buoys and around the coasts of the Cape of Good Hope, quite justly also named "Cape of Storms". We had much experience sailing in mild weather and in those storms.<br />
<br />
Gavin Muller, at 21, was not long out of college. His math teacher, an acquaintance and also a boat owner at Royal Cape Yacht Club, had asked me if I had a crew slot available for Gavin, who had previously sailed a Cape to Rio Race with him while still a school boy. Another friend of mine had to withdraw from the crew and Gavin slid into his spot.<br />

"Black Cat" is the prototype of my Didi 38 radius chine plywood design. I designed her primarily for this race, starting to formulate the concept while racing to Rio in 1993 as navigator and sailing master on the Shearwater 39 "Ukelele Lady". I built her in my garden in Hout Bay, a suburb of Cape Town. The build took 2 years with help from my wife Dehlia, Sean Collins and another friend, Nigel Watkins, who didn't join us for the race.<br />
<br />
Part-way through that race, with the nearest land (the Brazilian island of Trinidade) about 500 miles away, we had a close call with a boat of about 40ft that was sailing unlit on a moonless night. I was in my berth under the cockpit, dozing with my brain on alert as usual. Brian and Adrian were in the cockpit and I heard a discussion start, trying to identify something ahead of us in the dark. We were under spinnaker, averaging about 10 knots, so closing pretty fast. I joined them in the cockpit to see that we were on course to T-bone this wooden boat. Two wooden boats colliding in mid-ocean would not have been pretty. The skipper of the other boat suddenly appeared on deck, shining a flashlight on his mainsail. Within another 15 seconds we would have been past him and would have made much noise to advise him that he had missed out on the action of unidentified ships passing in the night. I suspect that he still holds those images in his head of our big cat spinnaker bearing down on him fast.<br />
<br />
We figured from his course and position that he was possibly en-route from Cape Horn to Europe. Next morning on the daily fleet report I told of our near-miss. The story appeared in the Cape Town newspaper next day, although not entirely accurately reported. We were also the subject of the daily cartoon, the original of which now hangs proudly on my wall at home.<br />

We had not seen our competition "Kelly Girl" since the start but they were always close behind in the handicap race. We hadn't seen another boat for many days although the position reports showed that there were always others somewhere over the horizon. Trinidade was a mark of the course and, as we approached the island toward sunset one day, we saw "Kelly Girl" behind us on the horizon. After that we saw each other at least once a day.<br />
<br />
A few days after rounding Trinidade we were sailing in 5000m of inky blue water that suddenly turned brown and murkey. We hadn't seen a seabird for a few days and had hooked nothing on our fishing lure, trailed for many days. At the same time the sky was full of birds and our lure hooked a long-fin tuna. Within 5 minutes we had three of them aboard before deciding to keep the lure aboard rather than have nature think us greedy. The truth is that, with one fish for dinner that night and the other two in the freezer, we could not cope with any more. Within an hour we were back into inky blue water and 5000m of water, having completed our crossing of the 60m depth of the Almirante Saldanha Sea Mount. In another million years or so maybe this will be another island in the Atlantic.<br />
<br />
Meanwhile our race-within-a-race carried on with us sometimes ahead and other times "Kelly Girl" appearing out of a thunder storm ahead of us. Cabo Frio was our first landfall in mainland Brazil and we rounded that promontory abeam of each other and 100 yards apart. We finished about 3am that night, about an hour ahead of "Kelly Girl", with the 20 minute handicap advantage in hand as well. Another 4 years on, in the 2000 Cape to Rio Race that same boat was skippered by circumnavigator Anthony Steward, who finished about 20 minutes ahead of us. These two boats are very closely matched for ocean racing.<br />

Since that 2000 Rio Race "Black Cat" has crossed this ocean twice more, to total six Atlantic crossings. She has also raced the 1700 mile Governor's Cup Race from Cape Town to St Helena Island twice, including line- and handicap-honours in the 2014/15 race.<br />
<br />
It is now 24 years that "Black Cat" has been sailing. She has nearly 100 sisters on the water or in build. She has also spawned another 16 performance designs in sizes from 15 to 55ft for a wide range of concepts. These range from monohull dinghies to trailer-sailers and large catamarans, even fast little gaffers. More than 500 boats are on the water or being built to this range of designs. Most are amateur projects, with builders producing impressive quality.<br />
