That Puzzling Paper Jet

The Paper Jet was a plywood kit boat right from the start, from the first thoughts of the concept that started to take form in my mind. Later we added a build-from-plans option to allow more people to build it, those who prefer or need to build from scratch. This could be that they need to reduce cost, they prefer the challenge of doing the complete build themselves or for other reason. Until now, whether building from plans or a kit, jointing of the long panels of the 4mm plywood hull and deck has been done by means of butt joints that are reinforced both sides with glass tape.

 Now we are up to Paper Jet #87, which is to be built in Weston, Missouri. The builder asked if it would be possible to supply his kit with jigsaw jointing of the long panels instead of the butt joints. This would ease the construction process for most builders, so I have reworked the panel files to add jigsaw joints.

To read more about jigsaw joints, see an article that I wrote on my Boatbuilder Tips blog.

For now the jigsaw jointed Paper Jet kits are only available in USA but the files will be available to all of our kit suppliers worldwide. If you want to build this design from a kit and want it to have jigsaw joints, email me or contact your choice from out kit supplier list. I will send the jigsaw-jointed kit files to the supplier.

Jigsaw joints are impractical for building from scratch, so those building from plans must continue to use the glass-taped butt joints.

Wooden Boat Festival

I have been trying for years to get to the Wooden Boat Festival in Port Townsend, WA, but have somehow never managed to put it together. The 2014 event will be the 38th rendition of the annual festival, which grows each year in size and what it offers. It is organised by the Wooden Boat Foundation under the umbrella of the Northwest Maritime Center. In 2014 the  Festival will run from Friday 5th to Sunday 7th September.

This year I am finally going to make it to the Wooden Boat Festival. I expect to be there all three days and will be a speaker as well. I am scheduled to present on the subject "Plywood Boatbuilding Methods" from 10h45 to 11h45 on Friday 5th September, in the Discovery Classroom.

The Wooden Boat Festival boasts over 300 boats on display, some in the water and others on land. There are also about 150 presentations and demos, covering a wide range of subjects about every imaginable subject either directly or indirectly related to wooden boats.

There are many wooden boats of my design in the Pacific Northwest. If you have built one of our wooden boats in the area or know someone who has, it would be great to get a bunch of those boats to the show to exhibit. I always enjoy seeing the completed boats, meeting the owners and chatting to them about building and sailing their boats. Owners generally enjoy meeting other builders and swapping ideas and experiences. This can be a great occasion to do just that. I can't arrange for the boats to be exhibited, that must be arranged with the organisers through their website.

Even if you don't have one of our boats to exhibit, I would be pleased to chat at the show. You can catch my presentation at the time and place given above and there will be time to chat afterwards. Closer to the start of the show I hope to be able to pass on info about where to find me at other times as well. Keep tabs on this blog for updates closer to the time.

Hope to see you there.

Paper Jet, Designed for Junior Sailors

I designed the Paper Jet primarily to be a training boat for teenagers. The thought to design such a boat started when I was on sailing committees in South Africa. One of the subjects most often discussed was how to keep the juniors in sailing. They are the future of sailing, which is experiencing a gradual ageing of the participants. If we can't keep the youth interested in boats and sailing then they will wander off into more exciting/interesting activities, to the detriment of sailing as a whole.

The problem as I see it is a combination of factors, some inter-connected. There are no-doubt other factors but these are the ones that are apparent to me.
  1. Boats that are pushed by clubs and national bodies but are uninspiring to young sailors, in terms of performance and aesthetics. Most of these boats were advanced designs when first developed but are now very dated and unexciting by modern standards.
  2. The high cost of acquiring and maintaining competitive boats in the Olympic program. These boats are one-design to reduce costs and maintain level competition. However, they are built to very close tolerances and with top grade hardware, sails, rigs, foils etc, all of which cost a bundle of money when new. Much of that cost is repetitive as well, due to regular replacement to stay competitive. Most families cannot make this level of financial commitment, so the boats become progressively less competitive and the sailors lose interest.
  3. The high cost of upgrading performance/excitement/challenge to move into the next class up the ladder of the Olympic track. The need to sell the older boat, probably at a loss, then buy a competitive new boat that would be faster but not necessarily much more exciting, makes this an expensive process.
  4. Too much emphasis on winning and too little on getting enjoyment out of boats. This has resulted in very structured sailing activities for the juniors. They do not have enough freedom to use their boats for fun instead of being shepherded by adults in sail-training programs that are designed only to improve racing skills, not to engender a love of boats and boating. Fifty years ago we had much more freedom to sail in the manner that we wanted. In doing that we raced informally (two boats near to each other are always racing), learned how to get the most speed from our boats, how to capsize them, how to right them, how to sail them on the limits of the boat's ability and beyond our own limits, which served to push our own limits to the next level. We went onto the lake with only the need to be home for dinner and to take total responsibility for ourselves and our boats until we returned. In the process we developed instinctive sailing abilities that can come only from doing, not from being taught theory or chased around a race course by instructors. There were no rescue boats on duty on weekdays, so we had to learn how to rescue ourselves and our buddies. We became totally self-sufficient, self-reliant and confident in our own abilities. We learned to take responsibility for our own actions in a way that is missing from much of modern society. We also learned to love our boats and sailing so intensely that most of the guys in my group moved on to careers in the boating industry.
  5. Too much emphasis on windward-leeward racing. This may be good for emphasising the need for improving technique in slow boats but it produces the most boring type of sailing imaginable, either to participate or to watch. The most fun and exciting experience of sailing happens on reaching courses and the sailing establishment seems to have colluded to remove this from the racing.
What has all this to do with the Paper Jet? The concept of this boat developed in my mind and then in my computer, with these factors in my mind. I was developing a boat to solve some of those problems. No boat can fix everything that is wrong in junior sailing but I wanted to draw a boat that would have the ability to at least help with the problems. It produced a boat with the following characteristics.
  1. Very modern and exciting to look at, it looks fast even when standing still. Wherever I take it, people come to admire it and talk about it. Juniors love the aesthetics of this very sexy-looking boat.
  2. It can morph from a very basic free-standing una rig for single-handing with minimal strings to pull and understand, through a conventional sloop rig for double-handed sailing with a few more strings, to a powered-up double-handed skiff with fathead mainsail, asymmetrical spinnaker and trapeze, simply by adding or removing components from the modular rig.
  3. This happens without changing boats and at moderate cost. One family can sail the same boat in different formats to suit the people who are sailing it. Or the same crew can vary the power of the rig and speed of the boat to suit wind, water and personal mood, from relaxed unpressured cruising through to very challenging maxed-out adrenaline-producing low-flying. It can morph from one rig to another in minutes, then back again.
  4. Planing high-performance hull with low drag at all speeds. It accelerates smoothly, with no bow-wave hump to overcome in order to plane at high speed. This means that it can plane in moderate breezes even with the smallest rig.
  5. Proportioned for teenagers rather than adults, so that juniors can potentially get more performance from the boat than their larger and heavier parents.
  6. Hull and deck weight of under 45kg (100lb), easily manhandled by young crew.
  7. Able to be built by amateurs with basic woodworking skills to reduce the cost of getting afloat.
  8. Traditional rig details to reduce expensive purchased hardware.

The drawing above shows the overall concept of the Paper Jet. In the plan view, you can see that it has two mast positions, linked by a plywood X-structure that spreads the rig loads into the hull and holds the jib sheet fairleads. The una rig at right has the mast free-standing in the forward mast position, which rakes it aft for good helm balance. The sloop rig at centre has the same mast moved to the upright aft mast position, with only the standing rigging and jib added. The skiff rig at left keeps all of the components of the sloop rig except for the removable topmast (there is a socket with locating bolt at the hounds) and mainsail, which are replaced by a taller topmast, fathead mainsail and spinnaker gear. The retracting bowsprit is linked to the spinnaker halliard so that one line hoists the asymmetrical and pushes out the bowsprit. The other end of the same line retrieves the spinnaker and pulls in the bowsprit.

The cockpit section shows that this boat has a narrow waterline relative to overall beam. That produces a boat that is very responsive and needs fast reactions and agility. It is not a boat for beginners, who should first learn to sail on a Sunfish or other less challenging boat. After that they will have the skills needed to sail this boat with the una rig then progress to the other versions.

The wooden mast that I designed for it is sealed and buoyant. If capsized it lies on its side instead of turning turtle. Most dinghies that lie on their side will blow away from the crew in strong winds if they lose contact with the boat. They can't catch up with the boat when swimming in a lifejacket. Not so with the Paper Jet, which stays right where it capsizes, with the immersed wing serving as a sea-anchor.

Righting from a capsize is not difficult, using the righting lines under the wings. Hanging from the righting line and pushing with feet against the immersed bottom of the hull pulls it upright, generally without a need to get onto the daggerboard.

The  Paper Jet is well-suited to club use, with boats able to be built by amateur or professional builders, working from plans (supplied with full-size patterns of all plywood components) or from pre-cut plywood kits available from suppliers in various countries (Click for suppliers). That makes it suitable also for club, school and community woodworking projects to build up local fleets.
Two Paper Jets are a compact load on a shared trailer.
I have no aspirations for the  Paper Jet to become an Olympic class. What it can be is an affordable, exciting and versatile part of the training route toward much more costly skiffs like the 49er. For those who don't have aspirations to Olympic skiff sailing, the Paper Jet can be all that they need.

Although intended for junior sailors, this boat has attracted a different type of sailor. It has earned a following of men in their 30s and 40s, sailing both crewed and single-handed. At time of writing, we have sold plans and/or kits for this design to builders in 18 countries, with numbers rising in North America and Europe.
