my new boat

The 2015 edition of the Wooden Boat Festival in Port Townsend, Washington, happens 11-13 September. Organised by the Northwest Maritime Center, it is their premier event of the year, attracting hundreds of wooden boats of all description, a wide array of exhibits and with 120 speaker sessions on boating subjects.

Some of the boats at the 2014 Festival, Didi Cruise-Mini in right foreground.

I will be taking part in three sessions, one on each day of the Festival.

Friday 11th - 2:45pm - Yacht Designers Panel Q&A - six designers to field your questions about boats and designing them. A session like this highlights the variety of opinions held by different designers on boating issues.

Saturday 12th - 2:30pm - Plywood Boatbuilding Methods - PowerPoint presentation showing information and details of the methods for which I design, illustrated with drawings and photos of my own projects and those of amateurs who have built these designs.

Sunday 13th - 1:15pm - Plywood Kits for Larger Boats - PowerPoint presentation about constructing kit boats that are larger than open dinghies and kayaks. This will cover boats from a 21ft lapstrake plywood trailer-sailer through to a 55ft radius chine plywood cruising catamaran.

The Didi Cruise-Mini "Segue" of David Blessing will be there among the on-the-water boats but I don't know yet what other of my boats will be there.

When not involved with other things, I am happy to meet with builders or anyone interested in my designs. If you can't find me then visit the Didi Cruise-Mini. Whoever is in attandance at the boat should know where I am and how to contact me.

If you are in the Pacific Northwest, or able to get there, this is an event worthwhile visiting.

Assembly of the prototype Dix 470 plywood kit by Exocetus Yachts in UK is progressing nicely. This is the second hull, with improvements added into the kit since assembly of the first hull. These photos were sent to me by Exocetus.

Exocetus is able to use more advanced methods than would be used by amateur builders but the kit is set up to allow those with more basic facilities to produce comparable quality. Being the developers of the kit, they have cut all of the components themselves on their own CNC equipment. They also have a large press that they use to join multiple sheets of plywood into long panels or other large components, like bulkheads, cabin soles etc.

Sheets being joined into long hull panels by means of a press.

This long outboard hull panel was pre-assembled into one large piece before installation.

Inboard hull side fitted, with horns for major bulkheads projecting into the bridgedeck area.

Bottom panels were fitted installed.

The side panels were glued into longer lengths for convenient assembly with the equipment available to Exocetus. For my own projects and more primitive methods, I prefer to assemble skin panels in single-sheet lengths. This leaves considerably more scope for adjustment during installation to remedy any possible errors that arise due to builder error. The bottom panels were installed in single-sheet lengths, to allow accurate fitment at the centreline joint.

In the last photo above, the jigsaw joint was aligned using a strip of plywood, wrapped in plastic tape, as a temporary butt-strap. A short screw into each lobe of the jigsaw pattern ensured accurate assembly and held the joint securely until the epoxy had set.

Kevin Bream is the owner of Exocetus Catamaran Kits in UK, the company that he formed to develop kits for our plywood catamaran designs and to market them to builders, both professional and amateur. To be sure that he does a proper job of this, he is building the Dix 470 himself, to test the fit of all parts and to develop systems to ease the whole construction process.

The number of plywood components in a boat like this is massive. Just the thought of figuring the size and shape for each one, then cutting it out before fitting it in place on the boat, can make the project being contemplated seem very intimidating. Anything that can be done to reduce the number of hours in the build and the flow of elbow grease from builder into the boat is worthy of consideration. It reduces building time for any kind of builder. For a boatyard it increases profits and for the amateur it gets him afloat and sailing sooner.

Kevin Bream has one hull completed and is now working on the second. Lessons that he learned while building the first hull have been put into making a better product. Aside from that, anyone who buys a kit from Exocetus will benefit from a product that has been built by the supplier himself. Who could provide better backup support to the builders than he who has done the development, the cutting and the building before them?

Here are recent photos of the project.

I designed the Didi 29 Retro for Mike Kopman, a professional charter skipper who lives in my hometown of Hout Bay, South Africa. Mike's concept was to adapt the Didi 26 cruiser/racer design to a more traditional concept, with counter stern, bulwarks, boxy trunk cabin and a big gaff rig, for participation in the Caribbean classic racing circuit. Mike received the first CNC kit to this design, supplied by CKD Boats in South Africa. The second kit went to Bruce Mierke of Murphy, North Carolina, which he ordered from our list of plywood kits.

Mike Kopman has been building his workshop ahead of the boatbuilding project, so that hasn't started yet. Bruce Mierke started his boat a few months ago and is moving along very well. These photos are of Bruce's build. He began with some smaller items ahead of starting the hull, so I am showing those first.

Howdy Bailey Yacht Services in Norfolk, Virginia, is building the keel for the Didi 950 project in Ohio. This one has a fixed keel that is supported by a steel box on the inside of the hull and which is bolted to the grid structure. The box also forms the engine beds, to concentrate these major weights in a tight area for low pitching characteristics in lumpy water.

Howdy and his staff are doing a masterful job of building this keel, which is assembled over a rigid skeleton of schedule pipes between end plates. The side plates are wrapped over the skeleton and plug welded.

Same stage, looking at the top plate.

The tubular internal skeleton, instead of transverse plate spacers, has multiple benefits. The pipes make the skeleton very rigid to resist twisting when fitting the side plates, they have soft surfaces to minimise hard spots that can distort the side plates, they present broad surfaces for plug welding the side plates and they serve as efficient heat sinks to draw heat away from the plug welds, minimising heat distortion.

The keel bolts bear on the keel box inside the hull, sandwiching the hull skin between the the two. Howdy Bailey Yacht Services fabricated the box as well, then shipped it to the builder. He has test-fitted the Beta 15hp motor on the beds ahead of installing the box into the boat. The following photos show the box with engine standing on the integral engine beds.

Finding a suitably qualified engineering company to make the keel is often a worry for people considering building an offshore boat. Howdy and his staff have the experience and are available for this work.

Yesterday "Black Cat", the Didi 38 prototype that I built in my back garden in 1994/95, finished the 1720 mile Governor's Cup Race from South Africa to St Helena. At the time we had not yet seen any photos of her finish. Now some nice photos, taken by Trevor Wilkins Photography, have been posted on the Governor's Cup Facebook page. Here is one of them, see the others on the Governor's Cup pages.

When I wrote my piece yesterday I was still seeing the breaking news about "Black Cat" being the true line-honours winner instead of "Avanti", which finished ahead of her. I was concerned that there may have been a measure of speculation in the reports and that they may prove untrue. Now we know that the reports were correct and "Black Cat" is the true line-honours winner in the racing division and likely handicap winner as well. We won't know for a few days yet if "Iechyd Da" can catch her on handicap.

Don't let the small size of the racing fleet at the finish detract from the achievement of Dave Immelman and crew. All boats in the original racing fleet were well behind them and most jumped ship when the breeze went light and their sailing progress became too slow, deciding to change to the cruising class and motor through the calm patches. The NOR, as amended, did allow the racing class boats to do this but they had to notify Race Control of having motored at the "earliest opportunity" as well as in their declaration at the finish.

"Black Cat" was committed to racing and that is what they did, battling through the calms. It must have been soul-destroying to see another competitor in their class sail around them, apparently in stronger breeze, then continue to take line-honours in monohulls and racing class. Declaring hours after finishing that they had in fact motored and then being allowed at that late stage to drop down to cruising class is just wrong on all levels.

Did they in fact advise race control in the next daily position report after motoring and race control forgot to move them into the cruising class? This would seem odd because they would have seen themselves still in the racing class in the daily results and should have again told Race Control of the change that they had made. If they didn't tell race control then the act of motoring was an immediate DSQ from the racing class. If they didn't transfer correctly into the cruising class in the way permitted by the amended NOR then they should not be allowed to do so after finishing the race either. My opinion is that they are DSQ in the racing fleet and did not join the cruising fleet because they did not act according to the amended NOR. It follows that they didn't complete the race even though they completed the course.

Their continued listing as apparent leader of the racing fleet added interest to the race but skewed the daily results of both monohull fleets. It also had considerable effect on the moral of other competitors. I believe in absolute fairness and sportsmanship in yacht racing and all other sports but there appears to be something lacking in that regard with this situation.

I will watch with interest to see the final results.

We all learn in school about the "ship of the desert", the much maligned camel. These animals and their owners are totally adapted to living on and cruising the undulating surface of the desert. We also know of the traditional boats of the Arab world, the dhows that are seen in both power and sail versions. These are very seaworthy boats and have done extensive voyages.

Not heard of nearly as often in that part of the world is the construction of a modern high performance yacht. Such a construction project is the Didi Mini Mk3 of Hugo Vanderschaegh, proceeding apace in Dubai. This is a Mini 650 racer that is built from plywood. Designed primarily for amateur builders, this one is being built by professionals. The photos below show the hull with all flat sheets fitted and the radius skin starting, through to hull turning.

This boat is being built from a CNC kit that was supplied by our Cape Town kit supplier, CKD Boats. They are able to supply kits for most of our radius chine plywood designs as well as the classically-styled lapstrake designs.

They turned Hugo's hull right-way-up last week and recorded it on time-lapse video. They accomplished it with plenty of helping hands and no mechanical equipment. This is a wide boat, at 3m beam, so it towers above the men providing the muscle power. It worked in their situation with lots of hands but "don't try this at home". For the average builder it is better and safer to use mechanical equipment to raise one side under control then lower it again on the other side.

You can see more of his Didi Mini Mk3 project on Hugo's website and follow future progress. Also visit our website at http://dixdesign.com/ to read more about our range of designs and available kits for our plywood boats.

We now have a kit supplier in Russia, in Irkutsk, near to Lake Baikal in Siberia. The supplier is Boat-Kits Russia and is owned by 39 year old Peter Tatarinov. Initially he is offering plywood kits for our dinghies, the Dixi Dinghy, Argie 10, Argie 15 and Paper Jet. Later he will expand into our small to medium size plywood keelboats as well.

Peter has a shop fitting company with CNC equipment, has some dinghy sailing experience and is currently building a small boat. He has decided to expand the use of his CNC equipment to offer boat kits in addition to the furniture. We have sold plans for many boats to builders in the Irkutsk and Lake Baikal areas, so there seems to be a vibrant boatbuilding community there.

Kits can be ordered directly from  Boat-Kits Russia or from our Russian Agent Andrey Popovich in Vladivostok, through his website http://www.chava.ru/.

Peter also has CNC equipment to cut metal, so he would be able to cut kits for our metal designs as well if needed.
