Update on 50ft Catamaran in North Carolina

I visited the 50ft catamaran build by CRW-Con in Edenton, North Carolina last week. The first hull has been turned over and work has started on the second hull. The photos and captions tell the story.
Outboard view of the port hull. The hull has been sheathed with a layer of 1708 glass, then faired.
Inboard view of the starboard hull. The bulkhead horns projecting from the hull are for scarphing to the bridgedeck bulkheads.
Bow view. To the right is the long spar table for scarphing timbers into the hull-lengths needed to install in one piece.
Stern view, with the boarding steps taking shape. Rudder and P-bracket already installed.
Bulkheads being set up on the stocks for the starboard hull

Cruising keel.
Composite chainplate being formed on plywood panel. This is the first panel that will be fitted onto the hull framing, then the others will be fitted working toward bow and stern. 
Close-up of the incomplete composite chainplate. The carbon spreads the loads down into the hull skin and structure and the shrouds are attached in the gaps with soft lashings. 
Faired-in opening for flush-fitting porthole.
Formed opening for flush-fitting escape hatch, The boxing over it is part of the 45 degree splayed panel that will connect the underside of the bridgedeck with the inboard hull side.
This boat is a modified version of out Dix 470 radius chine plywood catamaran design, stretched to 50ft. Both are sisters to the DH550.

Hout Bay 30 Cutter New Launch

Another boat to our designs has been launched in Russia. This one is a steel Hout Bay 30, built by Aleksander Kokorin of Kranoyarsk in Siberia. He launched into the Yenisei River, which is the largest river system flowing into the Arctic Ocean.

The Hout Bay 30 is a frameless design, so the hull is built over temporary frames that are removed at the time of turning the hull over. I have a few photos from the start of construction in 2009, then a big gap through to those at launch in 2018.
The temporary frames have been set up on the building stocks and the centreline stringer fitted.
The transom has been set up. The stringers will be tack-welded to the tabs that can be seen projecting from the frame edges.

Filling the Bilges of the Sportfisherman

Kevin Agee is building his 26ft sportfisherman in a rented industrial unit in Seaford, Virginia. He plans to complete her and launch in time to go fishing in summer 2019. Each week of evening and weekend work takes him another step closer to that goal.

Having built three big boats myself, of 36ft, 34ft then 38ft, I know very well the commitment needed for a project like this one that Kevin has taken on. It takes drive and determination to do it. The skills develop along the way, to produce a high quality boat of which he can be proud. The standard of work that is seen on the hull shows his dedication to creating that quality boat.

Work that is going on now is all below deck level and on the deck panels themselves.
The bilge is broken up into compartments by the bulkheads and girders.The large ones on centreline are for tanks, batteries and pumps, accessed via hatches and access panels and draining to bilge pumps at the transom. Most of the others will be foam-filled and totally sealed.

Meanwhile, alongside the boat the deck panels are being glassed, with heavy glass on the top and a light layer and peelply on the bottom.

Cape May 25 Build in Russia

I am so often pleasantly surprised by the standard of work done by amateurs building our designs. They are dedicated to turning out boats of which they are justly very proud. I recently received photos of the gaff cutter Cape May 25 being built to a very high standard by Andrey Koslov in Voronezh, Russia.

Voronezh is a city of about a million people, in southwestern Russia, straddling the Voronezh River. The city was rebuilt after the Second World War, having been almost totally destroyed in a battle with German forces.The Voronezh River is a tributary of the Don River, flowing south into the Sea of Azov, which gives access south of Crimea to the Black Sea via Kerch Straight.
Very fair hull, nicely finished

Over she goes, with a pair of frames built around her.
Turning frames that double as her cradle. The fine hollow bow at waterline is one of the reasons why these boats are so quick in light breezes.
Ready for the interior and deck to start.
Thank you Andrey, for doing such nice work building your Cape May 25. Keep up the good work.

50ft Catamaran Build in North Carolina

There is a custom sister to our radius chine plywood catamarans taking shape alongside Albemarle Sound in Edenton, North Carolina. The builder is CRW-Con and the build method is composite reinforced wood construction, adapted by the builder from our radius chine plywood method. The base design is our Dix 470, expanded longitudinally to 50ft. The 470 is the second in our catamaran range that started with the DH550.

This series of photos shows construction of the first hull, which will be turned over in the next week or two.
Bulkheads and backbone set up, with stringers fitted into bulkhead slots.
First layer of radius skin fitted, foam fitted between stringers and keel structure in progress.

Side skin completed, keel completed and glassed.
Glasswork completed.

This first boat has cruising keels and is being built on spec, with the builder seeking a customer for it. Interior configuration and finishes can be agreed between owner and builder if a buyer commits to the boat before the builder gets to a stage where he has to make those decisions. Anyone interested can email me, then I will put them in contact with the builder.

DH550 Catamaran Video

Today I saw a rather nice walk-through video of the DH550 "Cheetah", posted by Wiley Sharp. This boat was custom-built for her owner by Peter Lane in Trinidad, to a gorgeous standard. She has beautiful veneered finishes throughout, unusual for multihulls. Click on the link to watch the video.
The layout of "Cheetah" is a bit different from our standard layout, modified by her architect owner to suit his needs. The normal arrangement is four equal cabins, two in each hull with a large shared heads with shower between the two.

The other big difference between "Cheetah" and the other boats built to the DH550 design is in the powering. "Cheetah" has a pair of electric drives powered by large battery banks charged by solar panels backed up by a diesel generator. Each of the other boats has a pair of 50hp diesel motors.

"Cheetah" and most of the other boats have daggerboards but the design includes a cruising keel option, as fitted to "Friends Forever". The drawings also show the option of dual steering, one inside the saloon as used on "Cheetah", and the other in the forward cockpit. The two wheels share a common shaft that passes through the bulkhead that separates the two.

Cheetah was built from scratch, using plans only. There is a company in UK, Exocetus Marine, that has developed a very comprehensive CNC kit that includes all plywood components that go into the boat, to speed up construction of amateur and professional projects. Boats are being built in Australia, Germany and South Africa using their kits.

More recently we have introduced the DH550 Charter, with interior layout more suited to charter service, as well as aft elevated cockpit for helming and all sail handling.

Bilge Finishing in the 26ft Sportfisherman

I haven't posted about Kevin Agee's 26ft sportfisherman project for awhile. Since we turned the hull over, he and Michelle have been doing the rather awkward work of cleaning up then glassing all of the compartments inside the hull, below wet deck level. With a skin condition that does not get along well with lots of laminating and sanding epoxy/glass, I have stayed away from this work.
Sportfisherman 26 hull in its cradle. All the work is going on inside it now.
All of these bottom compartments have been sanded, glassed and sanded again. The inner hull sides have also been sanded smooth, ready for glassing.
The wide compartments on centreline will serve as the bilge, also housing the tanks, batteries and pumps, so will be finished smooth. The outer compartments will contain foam flotation sealed in, so will be left rough.
Inside the engine bracket has also been glassed.
This photo shows the detail used at the break in the sheer. The two laminated sheer clamps overlap and intersect as they do to give proper control over the shaping of the hull side surfaces and tying in of the sheer clamps with the frames.
The pain of glassing the bilge compartments could have been reduced by glassing both sides of the bulkheads and girders below wet deck level before installing those items into the structure, likely cutting the awkward work in half. But that is the value of hindsight and we know for future builds of this and other power designs that will follow.

Paper Jet Skiffs in Siberia

Siberia, Russia, counts Lake Baikal among its natural treasures. Lake Baikal contains the largest single volume of fresh water in the world. Irkutsk, on the shores of Lake Baikal, is the home of Ivan Vasilyev. He bought plans from us in 2009 for the Didi 26, which he built for himself and now races in the local fleet.

Ivan and a group of friends plan to build the bigger sister, the Didi 38, in the future. But at the moment they are working on a project with smaller boats and for a different purpose.

They are building a bunch of skiffs to our Paper Jet design, for sail-training at their yacht club. Our design was selected because of its versatility, able to be used by sailors of widely differing abilities due to the designed-in variations in rig configuration. Three basic rig configurations plus other options are possible from the modular rig components, without needing three complete rigs per boat. The Paper Jet can morph from a docile una-rigged single-hander, to a single- or double-handed sloop, with or without trapeze, through to a full trapeze skiff for two juniors or one adult, with fathead mainsail and asymmetrical spinnaker.

Ivan and his group have bought plans for six boats to date. Some are being built from plans only, others are from CNC kits that have been cut by our kit supplier in Irkutsk. The boats are progressing nicely, most of them being built in the same location.
The first Paper Jet starts, with bulkheads and backbone set up on the building stocks. The boat alongside is Ivan's Didi 26 "Orca".

I look forward to photos of this growing fleet, teaching new sailors of all ages how to sail and also doing class racing.
