guide to make 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.

Most of you will have read here or elsewhere about our adventure in the 2014 Cape to Rio Race on the Didi 38 "Black Cat". I have published a book about it, which can now be ordered from our website. For those who don't know what happened, here is a synopsis of the book, which is titled "South Atlantic Capsize - Lessons Taught by a Big Ocean Wave".

At dusk on 5th January 2014, the Didi 38 "Black Cat" was struck by a massive wave on the second day of the 2014 Cape to Rio Race across the South Atlantic Ocean. The wave capsized her in an instant, flinging crew, equipment and food around the interior and destroying most of the electronics with water that entered through the companion hatch. "Black Cat" recovered very quickly but the electrical damage was done. This is the story about the race, the boat, the crew and what happened on that day.

It also explains the principles of stability that control the safety of monohull sailboats, mostly those characteristics that affect the behaviour of boats in large beam seas that might capsize them and the features needed to quickly return them to upright. It does this in words and terms that can be easily understood by non-technical people.

Back cover.

You will also read the story of the capsize of the 64ft "Sayula II" in the Southern Ocean when sailing between Cape Town and Sydney in the 1973 Whitbread Round the World Race, written by yacht designer Butch Dalrymple-Smith, who was one of the crew. Also what one boat owner has added to his own boat to prepare it and himself in case they are caught by conditions that place them at risk of capsize.

I managed to coerce two of the crew to also put pen to paper, to each write a short piece about his experience. I felt this to be important because we all observe events from our particular points of observation and positions in life. My view from the inverted cabin roof of Sean Collins hanging on for his life in the cockpit and of Adrian Pearson flying like a rag doll around the cabin is very different from that of Sean looking down the steep slope of a monster wave and seeing the masthead spearing into the ocean below, knowing that the boat will follow deck-first.  I would have liked to have had stories from the other two crew as well but they did not feel capable of effectively putting their stories into words.

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.

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.

The 2014 Governor's Cup Race from Simonstown, South Africa, to the South Atlantic island of St Helena, is all done and wrapped up. The results have all been sorted and the crew of the Didi 38 "Black Cat" have been presented with the magnificent glass floating trophy.

The race started out in strong conditions that stayed with the fleet for much of the race, then disappeared. In battling through the extensive calms, most of the racing division boats chose to use their motors and defaulted into the cruising division, inflating the cruising fleet and decimating the racing fleet. Those who stuck to the ideals of yacht racing under wind power alone are to be congratulated for staying there to the end. In doing this, "Black Cat" and her crew won both line honours and on handicap.

For those who wonder where this place is, St Helena is the island to which Napoleon Bonaparte was exiled in 1815 after being defeated at the Battle of Waterloo. He was interred there in a tiny home until his death in 1821. The island is home to a small population of "Saints" under a governor who answers to the government in Great Britain.

The Governor's Cup Race occurs each year in the Southern summer, except for years when there is a Cape to Rio Race. It starts in late December and finishes early January, after crossing 1720 miles of open ocean. In past years boats have been able to ship back to South Africa on the RMS St Helena, a combined cargo and passenger vessel that has been the major physical connection between the island and the outside world in the past. Now the island has an airport that is nearing completion and which will soon be operational.

The RMS St Helena service will be cut back considerably now and shipping of boats back to Cape Town may not be possible. It will be interesting to see what effect this has on entries for the Governor's Cup Race in the future.

This is a worthy race to enter if cruising around the world and passing through Cape Town. Also for kicking off a long distance or world cruise with South Africa as departure. From St Helena, the next stop of the trans-Atlantic leg would likely be the island of Ascension, another weeks sailing NW of St Helena, then on to Fernando de Noronha and mainland Brazil.

I have not yet visited St Helena but it is high on my bucket list.

In my last post I wrote about how well the Didi 38 "Black Cat" was faring in the Governor's Cup Race to the South Atlantic island of St Helena. I am writing this post based on information that I have read on the official web sites of the race and False Bay Yacht Club.

They were going like a train in showing the way to all of the monohulls. Then they sailed into a hole in the otherwise good tradewind sailing breezes. This was created by a rather odd shape to the South Atlantic high, as an elongated sausage running east/west and in two parallel bands of calm not far apart.

Skipper Dave (Wavy) Immelman was kicking himself for having missed a crucial weather download that may have helped him evade the holes. They sailed slowly through the first calm then the winds started to pick up and they thought they were through, only to be trapped by the second calm.

We watched in dismay as the Vickers 41 "Avanti" sailed a big arc that took her right around the hole in which "Black Cat" languished, at pretty much twice the speed. We despaired for the chances of "Black Cat" even catching "Avanti" before the finish line, let alone getting far enough ahead to beat her on handicap. In the end "Avanti" crossed the finish line about 7 hours 10 minutes ahead of "Black Cat".

I went to bed last night feeling sad that the hard sailing done by Wavy and his crew for so much of the race was thwarted by the fickle winds. I woke this morning to the news that the skipper of "Avanti" declared some time after finishing that they had motored and were dropping down to the cruising division. That leaves "Black Cat" as the likely winner of the racing division, with only "Iechyd Da" with a very distant chance of beating her on handicap.

Congratulations to Wavy and crew. You sailed an honest and honourable race. You didn't deserve the heartache that came from watching your opposition apparently sailing right around you when they had actually motored into a more favourable position.

This brings up two questions that need clarification.

1. Why did "Avanti" wait until after the finish of the race to declare that they motored? They should have done so immediately that the motor was started. That action disqualified them from the racing division. They didn't declare at the time that they were dropping to the cruising division, so can they be considered to have been racing in that division? None of the other cruisers knew that they were racing against "Avanti" so they couldn't take her into consideration in their tactical decisions. The knowledge may not have had any effect but it should have been open knowledge throughout the fleet within hours of "Avanti" starting her motor.
2. What is the sense of allowing boats to change their racing division on the water? It may have seemed a good idea at the time that the rules were written but has created a very unfair situation on the water, unfair to those boats that were in the cruising division at the start of the race. The entry list shows 9 boats in the racing division and 4 in cruising. As the race has progressed and the boats ran out of wind, racing boats have chosen to motor and change from racing to cruising division. The leading boat in cruising division changed class after finishing and the 2nd boat changed very late in the race. The whole balance of the event has changed, with the original 9 racers reduced to 3 and the original 4 cruisers swelled to 10 boats. Three of those 4 cruisers have retired and "Tallulah" should get the trophy. Instead she is lying 3rd, with "Avanti" and "Strumpet" having jumped in ahead of her. Maybe the rules of the race have not been broken but I don't agree that this is the right way to do it, in the interests of fairness to all on the water.

OK, I am getting off my soapbox now.Once again, congratulations to Wavy and crew on sticking it out in racing division when it looked like you had been beaten but could have had a clear win in the cruising division by simply starting your motor and changing classes.

I am sure that most of my readers are well aware of our adventures on the prototype Didi 38 "Black Cat" in the Cape to Rio Race in January 2014. This is the boat that I built in my back garden in Hout Bay, South Africa and launched nearly 20 years ago. She was the experiment in boat construction that is the basis for all of my radius chine plywood designs, with many hundreds now on the water or in build around the world.

"Black Cat" is once again out on the wide blue South Atlantic Ocean. She is participating in the 1700 mile Governor's Cup Race from Simonstown, South Africa, to St Helena, the remote island in the middle of the South Atlantic. Much as I would like to have been there, I was unable to join the crew for this race but they seem to be doing a pretty good job of it without my interference. They have led the monohull fleet both on handicap and on the water from the first position report and remain up there. Only the trimaran "Banjo" leads them.

The crew, led by Dave Immelman, has been having great sailing, with three consecutive days of 200+ mile runs in strong downwind trade conditions. Now they are working their way through the light winds of a high pressure system at lower speed but maintaining their lead. Dave is the resident skipper on "Black Cat" and was my navigator for the Cape to Rio Race 2014.

We wish Dave and his crew continued good sailing and that they can find their way quickly through the high to more good breezes.
