my new boat

In November 1997 we launched our Didi 38 "Black Cat" after 2 years of building, only 2000 hours for an amateur-built ocean-crossing sailboat. That boat launched a whole series of designs and new developments in plywood boat construction.

That was 20 years ago. I had video of the occasion that was recorded off the TV with a VCR. It was bad quality and it was recorded on the PAL system used in South Africa. Attempts to convert to the NTSC format used in USA were pretty disastrous, resulting in unusable files.

Today I have received a good copy of the video, in a usable format. Watching the video now reminds me just how long ago this all happened. I didn't even have much grey hair then, now it is totally silver.
This video shows the shape of "Black Cat" very clearly. So many people came to me at that time and would not believe that this beautifully rounded shape was a plywood boat. Nobody had seen a rounded plywood hull before and they would only believe that it was not fibreglass after going inside to look at the structure.

Now my radius chine plywood designs are well-known and have been built in many countries. "Black Cat" is no longer unique but she remains the leader of an exciting time for plywood boatbuilding.

Summer heat is setting in and minds are turning to activities that can keep us cool. Time for us to get out on the water and go boating.

Time also for the Wooden Boat Show, which takes us north on a 500 mile road trip from the rapidly over-heating Virginia to the somewhat cooler climes of New England, more particularly the very beautiful Mystic Seaport. I must admit that in June/July I think that part of Connecticut must be a great place to live. Then I think about how much I dislike the (much milder) cold of a Virginia winter and know that I was built for much more tropical places.

The Wooden Boat Show  will be 26-28 June and we will once again be exhibiting our bright yellow Paper Jet prototype. Close by, in the "I Built It Myself" section, will be the prototype of our new 16ft garvey design. This is "Inlet Runner", exhibited by amateur builder Kevin Agee of Hampton, Virginia. He is working long hours into the night to get it finished in time for the show. It will be showing off its very fresh paint job. Never having built a boat of any size or type before, he has surprised himself with the high standard of work that he has achieved.

We are also using this opportunity to do the official launch of my new book "South Atlantic Capsize - Lessons Taught by a Big Ocean Wave". We will have copies on hand at a special show price and you may be able to pin me down long enough to sign your copy. Special show price only to those who visit us at the show.

I wrote in January about the 16ft plywood garvey being built by Kevin Agee. Kevin is progressing nicely and benefitting from the very welcome spring that has finally arrived and eased out the rather brutal winter. Now it is easier to do woodwork and epoxy cures much faster, so work progresses more quickly. Epoxy coatings in the sealed spaces are being completed and this weekend the deck will be glued on.

Hull skin completed, interior details being fitted.

Supports for battery box and fuel tank.

Deck stringers going in, test fitting of fuel tank.

Bottom runners serve as stringers and bottom protection.

Dry-fitting deck, ahead of final installation this weekend.

Kevin Agee is doing a nice job of his project and will display it in the "I Built It Myself" section of the Wooden Boat Show at Mystic Seaport at the end of June. If you want to see this boat, that will be the place to do it.

Plans are not yet ready for selling but should be in a month or two. We will offer it as plans and instructions, with options of full-size patterns or a pre-cut plywood kit.

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.

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.

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.

The long-awaited day arrived this weekend. Jim Foot, in Port Elizabeth, South Africa, launched his self-built DS15 at Algoa Bay Yacht Club. He started with a pre-cut plywood kit supplied by CKD Boats in Cape Town and took approximately 6 months of his spare time from start to launch.

DS15 "Bateleur" about to get wet for the first time.

 Despite the very light wind, they had good sailing and were impressed by performance. Jim's first comments are:-

She sails beautifully and she is fast. Beating into a chop in light wind this am going at about 3,7 kts felt happy. Then was told wind spd 4 kts by passing boat quite amazing.

Bruce Mierke is building a Didi 29 Retro in Murphy, North Carolina. Bruce is a professional boatbuilder, building her for himself and progressing nicely. He has now completed the hull and it will be turned over in a few weeks.

This design is based on the Didi 26, modified to create a more classic image. Carrying a choice of rigs, the squaretop Marconi rig below and two gaff rigs further down the page. It is a radius chine plywood design, round bilge from plywood and can be built from plans or a CNC kit. Although Bruce is a professional builder, I developed this construction method primarily for amateurs and they have built many boats to this range of designs.

Yachting Monthly have a very interesting  video of a capsize test on their YouTube Channel. I only became aware of it yesterday when it was highlighted by Scuttlebutt Sailing News.

Many have read the accounts that I have written about our capsize experience on the Didi 38 "Black Cat" in the Cape To Rio Race 2014. It is not possible to visualise what it is like to be there in that situation, even if you sit inside your boat and try to imagine it turning around you but this video goes a long way to help visualise it. It is not fully realistic because the roof stays at the top as the boat rotates, so the world is rotating around the boat rather than the boat rotating within the world around it. To provide better visualisation the camera needs to stay upright while the boat goes upside-down.

Bear in mind that this test is in flat water and the boat is rotated quite slowly from upright to upside-down, then rights itself quickly. Normally a capsize will happen in seas that are large and confused, so it is a much more violent process than seen in the video, with the boat being thrown in confused directions while it capsizes. Despite that, it is worth watching, to see the way that crew, equipment, etc was moved around the cabin and to see just how much water came in even in that still water.

It is not an experience that I would recommend to anyone, yet it is an experience that I am glad to have had and to have survived.

It also validates the toughness of the methods of construction that I have used for these plywood designs, that "Black Cat" came through with minimal damage.

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.

In a November post I wrote about the Didi Sport 15 that is being built in Port Elizabeth, South Africa, by Jim Foot. Jim has continued to build at a good pace and his boat is moving into the final stages of construction.

Jim has provided a steady stream of photos that document his project through all of its stages. He appears to be doing a very capable build and his boat should be sailing within months.

Jim bought a plywood kit from CKD Boats in Cape Town. It was cut by CNC router using cutting files that we prepared and supplied. Similar kits can also be cut by our other kit suppliers in other countries.

I have been working intermittently on a new 16ft design for awhile, the start of a range of small powerboats for protected water use. The design is still a way off being complete but the prototype is already being built by Kevin Agee in Hampton, Virginia and is progressing well.

I am using a garvey-type hull that can be easily built from either plywood or aluminium. It has Vee'd sections forward to soften the ride in a bit of a chop, with twisted bottom panels that run out to a shallow V at the transom for easy planing.

The version that Kevin is building has a self-draining wet deck with swivel seats on bases bolted to the deck. It has integral floodable tanks under the deck to hold bait and catch.There will also be a "sit-inside" version with bench seats, with the tanks under the seats.

Kevin is building from okoume plywood, cut from full-size paper patterns that we have supplied. When the design is complete then we will also offer plywood kits, cut by CNC machine. The photos below show the basics of construction as far as it has gone to date.
