my new boat

Jim Foot launched his Didi Sport 15 (DS15) a few months ago. After initial photos and reports Jim went quiet. I suspect that he busied himself with regular sailing to learn the characteristics of his new boat, to understand how she likes to be handled in a range of conditions.

Today Jim has sent another report, detailing his sailing this past weekend. He sailed on Algoa Bay, off Port Elizabeth, sailing in sportboat mode with the lead bulb on the keel. Starting with light breezes, it rapidly changed to 35-40 knots, as happens pretty regularly in this part of the world. Unperturbed by the gale force conditions, Jim and his crew Thomas Ochabski put in a reef, left the big asymmetrical stowed in its bag and carried on sailing. Jim says that there was a keelboat in attendance in case of mishap, which gave him the bravado to carry on sailing.

 Here are extracts from Jim's own words about his experience with "Bateleur" in these conditions.

Beat back to harbour (from about 2 nm offshore) and then had a blast reaching around for about an hour or more.   Great fun.   Naah, understatement, awesome, awesome fun!

For the first time really felt that things were a step up on the speed stakes.   When I was building the boat I imagined a mini Volvo 60 with associated responsiveness and upwind speed. And this is what I felt the boat was achieving.

He promises some GoPro video by the end of the week.

And what about light wind speed? More words from Jim.

The other thing, the boat is incredibly fast in very light winds with weight forward. Everyone who has sailed her in light conditions (<6 kts) has remarked about this characteristic.  Thanks Dudley for a great design.

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.

Every now and then a boat catches my attention and I think "Hmm, I wouldn't 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.

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.

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.

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.

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.

 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.

Here are the latest photos from Bruce, showing the beautiful standard of finish that he has achieved.

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.

The Saints are the people who live on St Helena Island, a remote island in the middle of the South Atlantic Ocean. They live on a mountain of rock that comes straight up out of the ocean, with steep cliffs all round and nary a beach to be seen. The terrain is very convoluted, with deep valleys and mountain passes. Until now, the only way to reach St Helena has been by boat or ship but soon an airport will be completed, making the island more accessible to others and opening up the world to the islanders. This is an interesting place to visit on Google Earth, to see how remote and inhospitable it is. The new airport can also be seen; consider the mammoth task that it must be taking to create it with the minimal resources available on the island. I imagine that much equipment and material has been shipped in over the past few years to accomplish this.

St Helena is the finishing point for the Governors Cup Yacht Race, sailed from False Bay Yacht Club in Simonstown on the western side of False Bay, South Africa, every two years. It was also the place to which Napoleon Bonaparte was banished for his second imprisonment. It was far enough away from anywhere else that he was not able to get up to any more mischief.

What The Saints Did Next is the blog for the island, which helps to keep the world up to date with whatever is happening on the island. The blog has a great post about "Black Cat" and her win in the most recent edition of the race. It includes an interview with the crew about the race and life aboard, as well as a bunch of really nice photos of "Black Cat" and crew.

I hope that I can be on "Black Cat" for her next voyage in this race. Visiting St Helena is on my bucket list as a place to visit. An ancestor of mine and the first Dix to settle in Cape Town arrived from St Helena. What he was doing there I don't know, possibly a soldier guarding Napoleon.

"Black Cat" is the prototype of my Didi 38 design and forerunner of all of my radius chine plywood designs. Visit our website at http://dixdesign.com for more info on my designs.

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.

Completed keel skeleton with pre-formed side plates awaiting fitting.

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.
