Plywood Boat Plans | Didi 950 Projects

Plywood Boat Plans

There appears to be considerable interest in my posts about the boats being built to our Didi 950 design. This is a radius chine plywood design with hard chine in the topsides, designed to fit into the Classe 950 box rule. In the past few days I have received a bunch of new photos that show the build process clearly, as well as some updated progress photos.

Before going into the new photos, you might like to read the article that I posted today on my Boatbuilder Tips for Amateurs blog about how to construct building stocks or beds, the foundation off which the skeleton of a wooden boat is built. It is illustrated with photos of the Didi 950 that is being built by Fred Grimminck in Australia. The photos below are mostly of that same project, being built from scratch without a kit.

The photo below shows the various backbone components, all of which slot eggcrate-fashion into the bulkheads. The slots help to locate the bulkheads and backbones correctly relative to each other. The bow and stern have single backbone on centreline and the mid-part of the hull as two backbones that run down each side of the keel support box. The two shorter pieces on the right are the paired double-backbone parts. Next toward the left is the aft backbone, which turns up at the far end to support the transom. Extreme left is the bow backbone, which turns up at the far end to form the stem and supports a bow bulkhead into which the forward ends of the stringers are located.

Didi 950 backbone components. Click on all photos to enlarge.

The photos below show a few of the forward bulkheads with the bow backbone dry-fitted in place. The backbone has doublers just below deck level for through-bolting the bow chainplate. The doublers can be seen at the forward lower end of the backbone.

In this next photo, the transom doubler has been set up as a doubler and the stringers etc run through, then are trimmed flush. When the transom is glued over the doubler the end-grain of the longitudinals will be covered and protected. Look through the 4th cutout from left through the doubler to see how the aft end of the aft backbone turns up against the inside face of the doubler. The backbone has locating tabs that slot through the doubler, seen as light-coloured marks on centreline of the doubler. In the lower photo the transom is being glued over the outside of the doubler.

The sheer clamps on this design sit diagonally across the corner at the intersection between hull sides and decks. They are screwed and glued to cleats on the faces of all bulkheads. In this photo the sheer clamp is clamped to those cleats. You can also see how the stringers are slotted through the bulkheads. Once the hull skin has been glued on, these junctions become very strong and rigid

Looking forward along the hull just prior to fitting the bottom skin. The wide stringers on both sides are the tangent stringers, with doublers to back up the joint between flat bottom panels and radius skin panels at the turn of the bilge.  The single aft backbone can be seen running through to the 3rd bulkhead from the bottom of the photo. The double backbone runs forward from the 2nd bulkhead from the bottom of the photo, then changes back to a single backbone further forward, also visible.

Stringers in the forward part of the hull, mainly showing the radius area. The two broad stringers are at the tangents, joining the flat and radiused skins together. Between them are three radius stringers, over which the double-skin radius will be formed. Below the lower of the two tangent stringers are the stringers for the side skin panels.

This last photo shows Mike Vermeeschs boat, being built from a kit in Ohio. Mike has the side panels all dry-fitted to check for fit ahead of gluing in place. Looks like a nice fit. The bow will be capped with solid wood, which will cover and protect the end-grain of the stringers.

Thank you to both Fred Grimminck and Mike Vermeersch for taking the trouble to send me these photos and allowing their use.

Boat Plans And Kits | New rig for Didi 29 Retro

Boat Plans And Kits

The Didi 29 Retro was commissioned by a client in Cape Town, to build for himself for competition in the classic yacht races in the Caribbean. He wanted a boat with modern underbody and appendages but with a large gaff rig of classic configuration, to race in the modern classic division.

Underbody of Didi 29 Retro

Last year I was asked to draw a more conservative cruising gaff rig for the design, to better suit those who have no aspirations to race with a big crew or simply want to cruise. That resulted in the cruising gaff rig with about 20% less sail area on the same foretriangle height.

This year I was asked to draw a more modern rig for it, which developed into the squaretop Marconi rig. This one will better suit most sailors, being easier to handle and easier to understand for those who dont know gaff rigs. On sail area, it fits between the two gaff rigs and it will be interesting to see how the three compare on the water.

Didi 29 Retro with squaretop Marconi rig

The squaretop Marconi rig suits the aesthetics of this hull rather well. It would be my choice if I were building this boat for myself. Should be an exciting boat to sail too, able to take advantage of the power of modern stable sail fabrics.

Boat Blind Plans | Didi Mini Mk3 Kit from CKD Boats

Boat Blind Plans

I would have to dig deep in my files to find when CKD Boats first started cutting kits to our plywood designs. Owned by Roy McBride, this Cape Town company has the longest history of cutting our kits and has shipped kits for our plywood boats to many countries around the world. They also have the most experience with packaging large or small kits securely enough to arrive at their destination without damage or loss.

The most remote was a Didi 38 kit sent to Johnston Atoll in the North Pacific. It was a very comprehensive kit that included all plywood, complete rig, keel, engine, sterngear, galley equipment, deck hardware, pulpits, sails and even pre-cut window panels and all the cushions pre-upholstered. This was all packed into a standard 20ft container and had to be shipped via New Zealand and Hawaii, all expertly managed by Roy, his staff and his subcontractors.

CKD Boats has just completed cutting a kit for the Didi Mini Mk3 for a customer in France. It will be packed next week for shipping.

Didi Mini Mk3 sheet fresh from the CNC router.

The plywood components are held in place in the sheets by thin tabs that are left between the full-depth cuts. They are released from the sheets by cutting through the tabs with a box-cutter or jigsaw. This system keeps the plywood as full 8x4 sheets for easy packaging and protection of the components from loss or damage.

Didi Mini Mk3 hull skin panels with jigsaw joints.

The Didi Mini Mk3 is one of the first boats that I converted to jigsaw joints instead of the stepped scarph joints that we used previously. This results in easier assembly and is easier to cut, with less machine time involved. These two panels both show a narrow cut on one side and a wide cut on the other. The wide cut is at the junction between flat and radiused panels, so it has a half-depth rebate pre-cut full length of the panel for the structural joint of the radius panel to the flat sheet.

When this kit is out of the shop, the next will start cutting. This is for a Didi Sport 15 to fill an order from a South African builder.

Plywood Boat Plans Australia | Cape Henry 21 Launched in Croatia

Plywood Boat Plans Australia

Dean Ivancic lives in Porec, Croatia. He bought plans from us a few years ago for the Cape Henry 21. He has been working steadily on his boat and reported to me today that he launched her in April. He has sent me some rather nice photos of her under sail. She is still incomplete down below but has all that is needed to sail.

She is named "Scintilla", Italian for "spark", also the meaning of "Iskra", the Croatian name of Deans youngest daughter.

We wish Dean and his family lots of fun and adventures in their Cape Henry 21.

"Scintilla" on one of her first outings.

Pretty from any angle.

Dean has done a nice job of building "Scintilla".

The Cape Henry 21 is surprisingly quick and has delightful manners. These boats prove that a boat doesnt have to be ugly to be fast.

Boat Plans African Queen | Sentinel Explorers Racing

Boat Plans African Queen

I designed the Sentinel Explorer for Sentinel Boats in 1991. My client was the importer of the Drascombe range of boats built by Honnor Marine but had not been able to sell any of those boats due to the high cost of importing them into South Africa. The brief was to draw my design to a broadly similar concept to the Drascombe Lugger but with sloop gunter rig instead of the yawl gunter rig of the Lugger.

My design was for a much fuller boat, with more volume on less overall length and very different hull section shape, resulting in a boat with more stability and considerably more speed. The UK builders of the Lugger took exception to the design and tried to shut down production, claiming that the moulds for our boat had been made from an existing Lugger hull, which was patently nonsense and no more than bullying the little guy in the playground. It lasted for several years but eventually went away, leaving a very bad taste for the low standard of business ethics displayed by Honnor Marine.

Ironically, Honnor Marine went broke and the company was bought by Bob and Norma Brown. The new iteration of Honnor Marine is now builder of my Cape Cutter 19 design in UK.

Production of the Explorer has been very low key, with small numbers built over the years. I heard a few years ago that there was a fleet of Explorers gathering on Langebaan Lagoon, on the West Coast of South Africa, with owners enthusiastic over their boats. Today I have received photos of this group racing as a one-design fleet in the Sandy Bay Yacht Club Easter Regatta. I have to admit that this is the first time that I have seen more than two Explorers sailing together. The time that I did see two together, I was racing one of them in the Hout Bay Dinghy Regatta, with my late friend Bryan Ferreira as crew.

Explorer start line action. "Dawdle", on the left, won the Easter Regatta.

It is good to see a smaller sister, the Sentinel Challenger, racing in the same fleet. The Explorer is only built in GRP from moulds but the Challenger can be built from plywood to our plans.

Boat Plans At Mystic Seaport | Long Distance in Small Boats

Boat Plans At Mystic Seaport

For as long as man has been on this gorgeous blue planet of ours he has sought to find adventure wherever he can. There have always been those who simply have to see what is over that next hill. When we all know what is over that next hill then the adventure becomes going over that next hill in some way that has never been done before. It has probably not been done that way before because it is just too big a challenge for most people to consider trying.

That insurmountable challenge is the best of reasons for some people to try it anyway, to prove that it actually can be done and to prove themselves to themselves. In the process of succeeding they also prove themselves to the rest of mankind. Some of mankind thinks it exceedingly silly to do these things and will be eternally critical of those who try. They have no adventurous spirit themselves and would never attempt anything that they consider the least bit risky or dangerous. Some of them become bureaucrats to control others or they encourage bureaucrats to stop the adventurers from being adventurous, a misguided attempt to protect them from themselves.

I have written here before about one such adventurous person, Anthony Steward. He is the only person to have sailed around the world in an open boat. I am fortunate that Anthony selected my TLC 19 hull as the basis for his open boat voyage. Everyone thought that he was crazy in his quest but he was permitted to do it. That is how it should be.

Now I am working on a design for another person who has the aim of circumnavigating the globe in a different way from how everyone else has done it before. His name is Davey du Plessis and he plans to peddle his way around the world. My job is to provide to him the boat that I believe will give him his best chance for success. At the same time, it has to be economical to construct because he is on a tight budget for the voyage.

The result is a multi-chine plywood craft of approximately 23ft length overall. The hull is of fairly classic form that will also make an excellent pulling boat. It has a fine bow at waterline for wave penetration and a fine stern for low drag at the low speeds that can be expected under long term human power.

Hull of the Ocean Peddle Boat for Davey du Plessis.

The superstructure is also multi-chine plywood, so that it can be quickly and easily built using stitch-&-glue building methods. It is a closed boat for maximum protection from the elements but with the ability to open up large surfaces of the central cockpit area to allow air to flow through when needed. This also increases the safety tremendously in rough conditions, making her essentially self-righting if all of the gear is properly stowed and secured.

Basic 3D model of hull and deck.

The model above is very basic, it doesnt show the details of the deck, like windows, opening panels, hatches, solar panels etc, which are detailed into the building drawings.

The whole concept is conceived to make a seaworthy boat. It is not designed for speed, it is designed for cruising slowly under human power, aided where possible by wind, wave and current.

What about the crazy man who will live long term inside this eggshell? Maybe Davey is not as crazy as you think or maybe he is more crazy than you think, I doubt that he knows for sure. He is no doubt less crazy than Anthony Steward because Davey has chosen to have a boat that will give him shelter for his long voyage. Does Davey du Plessis have the legs for this voyage? You can bet that he does, he has ridden a bicycle the length of Africa, from Cairo to Cape Town. Davey is an adventurer and I applaud him for it.

Daveys boat will be built in Knysna on the South African South Coast. The builder is his uncle, Tertius du Plessis, who has previously built one of my designs, a Didi 34.  I doubt that I will even get to see Daveys boat because his route is unlikely to pass anywhere near to me in USA.

I will add this boat to my website when the design is complete. I will no doubt offer it as an open pulling boat but it is possible that there are others who would also like to build it as a trans-ocean rowboat or peddleboat.

Boden Boat Plans Australia | Wickedly Accurate Didi 29 Retro Project in North Carolina

Boden Boat Plans Australia

I designed the Didi 29 Retro for Mike Kopman, a professional charter skipper who lives in my hometown of Hout Bay, South Africa. Mikes 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 hasnt started yet. Bruce Mierke started his boat a few months ago and is moving along very well. These photos are of Bruces build. He began with some smaller items ahead of starting the hull, so I am showing those first.

Rudder

Foil of lifting keel

Beaver-tail ballast bulb

Carbon spars for gaff rig.

Bulkheads and framework set up on building stocks.

This design has a spade rudder that is installed in a cassette so that it can be lifted out through the cockpit for trailing or shallow moorings. Bruce has added a motor well also, in which he will run a Torqueedo electric outboard. The casings that contain the outboard well and rudder cassette can be seen on the photo above and others in this series.

Bottom panels installed, rudder cassette and Torqueedo test-fitted

Radiused section of skin completed.

Aft view, with hardwood-veneered transom

Plug of engine well and rudder cassette in place.

Bruce has modified my rudder cassette design to allow some steerage with the rudder partially raised to assist when approaching shallow moorings with the keel raised.

He is very happy with the quality and accuracy of the kit that we supplied, describing it as "wicked accurate".

Boat Plans Catamaran | Didi 40cr Day Dream

Boat Plans Catamaran

Every now and then a boat catches my attention and I think "Hmm, I wouldnt mind owning that boat myself". Such a thought crossed my mind when I saw photos of "Day Dream". She is a Didi 40cr, essentially the same as the Didi 38 "Black Cat" that I built and sailed for so many thousands of miles, but with extended stern and a bit more accommodation space.

Fast as "Black Cat" is, "Day Dream" has the potential to be still faster. She has the same very slippery hull but her extended stern increases her speed potential. She has the same powerful but easily-handled rig, with a bit less draft, for better access to shallower cruising grounds.

"Day Dream" in the slings, showing off her clean lines

She was professionally-built in Antalya, Turkey, with CE certification. She has a radius chine plywood hull with fibreglass deck. She was a custom build, so the builder has made a few styling changes from my design but overall the boat looks really nice. I see European influences and features that are fine for local cruising in the Med. With my own preference for ocean voyages, I would modify the navigation and galley areas to better suit my own needs.

Nicely fitted out, with clean and comfortable saloon

Clean galley, styled for local cruising.

The asking price for "Day Dream" is not much more than the material cost of building such a boat, at US$60,000. If I had the cash available, I would be sorely tempted. If she rattles your cage enough to want to investigate further, contact me by email. I will put you in contact with the owner for more information.

Not the greatest sailing photo but the best that I have.

Boat Plans And Patterns | Cape Henry 21 Professional Build in Ireland

Boat Plans And Patterns

Tiernan Roe is a professional boatbuilder in County Cork, Ireland. His company, Roeboats, specialises in building quality wooden boats. Mostly of classic styling, they build for sail, power or rowing. Roeboats recently launched a Cape Henry 21 that they built for a customer from France.Tiernan sent me these photos, which show some interesting details brought into one of our most popular small cruisers.

Cape Henry 21 ready to get wet.

Launched in a pretty setting.

First sail of the new boat.

The mainsail has still to be fully set up in these photos.

Compact sink & cooker unit, neatly executed.

Other side of the galley. Nice detailing.

Looking aft from the double forward berth.

You can follow the construction of this boat on the Roeboats news blog, from start through to launch.

After launch, Tiernan Roe sent me these comments. "She sails very nicely and I found her easy to single hand from the get go. The interior is pretty snazzy with frame and panel oak fronted drawers and a gas stove with tank fed sink.  Also the centreboard was a lot easier to operate than I thought. Its an awkward shape out of the boat to try and move alone."
