my new boat

I designed the Paper Jet to be an exciting junior trainer, capable of taking a young sailor through multiple skill-levels, from a basic free-standing una-rigged dinghy through to a high-performance trapeze skiff with asymmetric spinnaker. This it does without having to spend bundles of money to trade up to another boat, by doing it all on the same hull and adding or swapping rig and hardware components. She is extremely light, with the hull weighing only 94lb, easily manhandled by small crew.

Paper Jet in una-rig Lite format.

It has proven capable of doing all that I intended, although I have used my prototype #001 as a single-hander for myself. I have cruised it in sedate fashion in light breezes, when it reels off the miles. I have also blasted on trapeze at well over 20 knots just clipping the tops of the waves. And between those two extremes she has given me many hours of fun and exhilarating sailing.

But, I have had knee problems since a teenager, from surfing too many hours in icy cold water without a wetsuit. Now, 50 years later, it has caught up with me. My knees won't let me get out on trapeze any more and my left knee dislocated at least 6 times while sailing this past weekend. In the middle of a tack is no time to be manipulating a dislocated knee back to its intended format.

So, the Paper Jet prototype, sail #001, is for sale. She comes with all components for all three rig formats as well as upgrades that I made to the design over the 8 years that I have sailed her. Included are:-

Standard mainsail
Turbo full-batten fathead mainsail
Jib on roller-furler
Asymmetrical spinnaker with sock
Mast with short and long topmasts
Boom
Retracting bowsprit
Daggerboards - three different lengths
Rudders - old and new versions
All deck hardware
All standing & running rigging
Launching dolly

Selling price is $8,000, which is not a lot more than the material cost to build her with all of the sails and bits that she has. She is in good shape, with totally watertight hull, just needing some minor paint and varnish touch-ups. We will have her at the Wooden Boat Show in Mystic CT this coming weekend, from Friday through Sunday. After that she will be back at our base in Virginia Beach VA.

If interested, please contact me.

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.

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.

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.

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.

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. It's an awkward shape out of the boat to try and move alone."

We have a new design that is a little out of the ordinary, named the Didi 29 Retro. It is a development of the Didi 26, which is one of our most popular designs with more than 250 plan sets sold. It has the same basic hull, keel options and interior arrangements but that is where the similarity ends. I think that, with the two boats lying next to each other on a marina, few people would realise that they are blood sisters.


This boat is intended for classic sailboat racing, so it needed a classic appearance. To this end we have:-

1) Extended the aft end into a counter stern. This will weigh a bit more but it extends the sailing length, for higher speed potential in stronger conditions.

2) Cropped the forward end to form a plumb bow.

3) Added bulwarks, both because it is a classic feature and to add spring to the sheer. The bulwarks are 100mm high in the bow and taper to a normal toerail height aft of the cabin, so that crew can sit comfortably on the rail.

4) Changed the cabin shape to a more traditional profile with almost vertical sides and compound curved roof.


5) Replaced the modern fractional rig with a big gaff cutter rig. It has carbon spars to reduce rig weight and increase stability. It is very versatile, allowing a wide selection of sail options, to really pile on sail area in the light stuff and reef it right down to a compact fully inboard gaff sloop rig in strong winds, and many variations between. The bowsprit pivots around the bow and retracts to stow on the sidedeck. The Genoa, Yankee and asymmetrical spinnaker are tacked to the bowsprit, so they can be pivoted up to windward for deeper sailing angles instead of being stuck on centreline.


These changes have morphed a very fast modern little racer/cruiser into a traditional racer/cruiser that will be capable of even higher speeds than the original design. It should be extremely quick in light winds and downwind in stronger conditions. The rig is a direct development of the rigs used on the Cape Cutter 19 and Cape Henry 21. Both are surprisingly quick little cruisers in the light to moderate breezes because of their large sail plans, yet are very capable in stronger conditions as well. However, they don't have planing underbodies and the Didi 29 Retro has inherited the planing underbody of the Didi 26, so should go like a witch downwind.

The standard keel options are lifting or fixed bulb keels. The rudder is a cassette that drops through the cockpit floor and locks in place for sailing but can be lifted out for trailing or access to shallow moorings.

The first boat will be built in Hout Bay, South Africa, by the owner. He will use a pre-cut kit of all plywood components, which will be supplied by CKD Boats . Builders will have the choice of building from plans only, plans with full-size Mylar bulkhead patterns or plans with a plywood kit.

The Didi 26 has to rate among our most successful designs. I designed it in 1997/8, so it has been around for about 13 years. In that time we have sold plans for 250 boats, so about 20 boats per year. They have been built by amateur builders on all continents and in far-off corners of the world.

I have no idea how many are on the water because only a small proportion of owners send me their launch and sailing photos. I am very grateful to those owners of our boats who do send photos of the build process and sailing once completed.

The most recent sailing photo that I have received for a Didi 26 was from Bill Richards on South Island in New Zealand. He has sent me a few sailing pics over the past year or two but the new one is very nice, showing his "Panic Knot" at speed under masthead asymmetrical in strong winds.

Bill added the following commentary to his photo.

"The conditions where extremely testing with a southerly wind that ranged from 5 knots to 30 knots. So we put up as much sail as we dared and went for it. We did wipe out several times both using the fractional and mast head kites. We tried very hard to break stuff but didn't succeed. max speed was 15 knots in flat water. And everything was under control on a good deep run, unfortunatley the course then called for a reach to the finish so we had to turn and try and carry kite, we managed very well until the gusts built to strong and then couldn't control it, ( the other boats wiped out before us) recovery was quick and I can now prove that the boat has a good righting moment, as we managed to have the mast head kite up and full main up with the top of the mast in the water!

What helped us was that the oppositon were flying conventioanl spinnakers and when they lost it they didn't recover as quickly as us. When we rounded up we didn't ever get as far as head to wind or worse as the oppositon did. The crew didn't even get wet feet as the boat on its side sits very high in the water. There is no chance of any water getting near the companion way.

The photo shows us doing about 12 knots."
 
We also have a 23ft version of this concept, the Didi 23.

A few posts back I announced the latest addition to our radius chine plywood Didi range, the Didi 28. This design was commissioned by an amateur builder in Greece who wanted a maxi trailer-sailer, along the lines of the Didi 26 but with more space and comfort.

Panel files are now complete for the bulkheads and all of the skin panels for hull, deck, cabin and cockpit. They can be cut by any of our normal plywood kit providers, who are listed on our kits page. The panel files will be supplied to whichever of those suppliers you choose to cut it for you. There are contact links to all suppliers on that page.

We have a new design, as of today. It was commissioned by Nick Sverkos, of Athens in Greece. He wanted to build the Didi 26 but asked if he could have more space. He particularly wanted more headroom and beam and was not concerned about his boat being a bit more than normal towing width. He set a maximum beam of 2.9m.




Computers and CAD are wonderful for taking a design and rescaling it to create bigger or smaller clones. In theory they can do all of the work for us and then we print the drawings of the new design. Designing stuff is easy, isn't it?

That is fine if all is scaled up by the same proportions. Open a drawing, tell the program to rescale by the amount you want, adjust here and there for differences in material thicknesses, refit the result to the output paper size then hit print. But!!!!!! Make the proportional adjustment in one of the 3 directions different from the others and  the situation changes completely. Shapes of all sorts of things change in ways that can be awkward. Circles become ellipses, squares go out of square and angles change. To simplify the whole issue I keep the proportional change in width and height the same so that the overall section shape doesn't go out of whack and the structural sections used for stringers etc don't go out of square.

Working with the Didi 26 as the starting point, I blew it up in all directions, more so in width and depth than in length. Next came another 100mm of freeboard, done by extending the hull sides upward without changing the side angle, so the deck became wider and the overall hull shape remained unchanged. After that I added another 100mm of height to the cabintop and adjusted stringer spacing to give a sound structure.

This all ended up as a large amount of redrawing for the structure. After all that the rescaled interior had some oddities, so I reworked that as well to make it work better. Final changes were reducing the cockpit width from the racing type of the 26, adding coamings for comfort and to give cubbyholes for winch handles, ham sandwiches etc, and a saildrive inboard diesel in place of the transom-mounted outboard.

The final result is a boat that will be a nice coastal fast cruiser. It will be light and stable enough for excellent speed, yet still able to get into shallow water. It will also follow the lead of the Didi 26 by being a great club racer. The sail plan is slightly more conservative than that of the Didi 26, yet this boat will still be fast enough for some exciting sailing.



 More info on the Didi 28 is at http://dixdesign.com/28didi.htm .

The new design is complete, aside from tying up a few loose ends. It is the Didi Mini Mk3, a very much updated version of the Didi Mini design that we have sold the past 10 years.

~ Extended cabin roof, forming protected cuddy over front of cockpit
~ Easier access between cockpit and interior
~ More power from broader and flatter stern
~ Water ballast of fixed keel version further outboard
~ Bow and stern ballast tanks in canting keel version
~ Tacking daggerboard in canting keel version
~ Redesigned foam flotation, cleaner interior
~ Inboard chainplates for tighter genoa sheeting
~ Larger square-head mainsail

Overall, these changes produce a boat that will be more powerful, faster, more weatherly and more comfortable to sail.


The underbody of this hull was developed from that of the Didi Mini, with the same profile and bottom shape but blended into a topside chine that runs from forward of the mast through to the transom. Combined with a full-beam transom, it adds more power to allow more sail to be carried for greater speed. See more info and graphics on the Didi Mini Mk3 web page.

We will continue to sell the older Didi Mini design for as long as people want it and the kit suppliers will still be able to cut kits for it.

Work has also started on our next design, a cruising oriented Didi 28 design. It will be a bigger sister to the Didi 26, with many of the same features but with considerably more beam, headroom and space. Watch for that to emerge next month.
