I belive that boat should be designed with inherent seaworthiness. That is boat is inherent seaworthy if it has a low level of getting into danger when the weather turns bad. For example my boats have centerboards that can be retracted when running downwind before a storm. That reduces the danger of broaching too. My boats are waterproof upside down, that in combination with freestanding strong masts and a secure place for all items eliminates the problems associated with capsize and pitchpooling. My body is fat adapted thus I do not need to eat or use the bathroom in bad weather. My boats steer themself. That eliminates the need for autopilots and windvanes that can break in strong winds.
I now also design the new Exlex, the Canoe Yawl as a symetrical double ender, . That way she can set a parachute anchor or drouge as desired from aft.
Sailing a boat with that low level of getting into danger when the weather turns bad is relaxing.
Below a video illustrates the thinking.
Thanks to evryone that has donated to support my project in connection with my 82 birthday the 22 of april.
Hi on the 22 of april 2021 I will if everything works out and the good Gods are willing, become 82 years of age. Very good. A big day for me. Cake will be eaten and even icecream in celebration. Please donate to my cake eating project and to my boatbuilding. Write if your donation is for the cake or for the boat in order that I will know where to put the money.
Update 2021 April 22 My friends at work gave me a cake. Picture below.
The text translates to something like “At last Yrvind 82”. I are a big chunk.
My boat project evolves nicely. Much more space than I had imaged. I only need 200 liter for water and 200 liter for 100 kilo food, musli and sardines, and some other stuff. The storage will be plenty more as can be seen in the video link below.
I had not realy planned this but now there is plenty of food to reach New Zealand in 200 days and 2.8 knot average speed from Madeira. The Canoe Yawl, new Exlex, will be 2 meter longer than the 2020 Exlex 7.8 to 5.8 meter, she will have twice as much sail area 8.2 square meter to 4 square meter. She will have the superior side by side biplane rig of the 2018 Exlex. I hope she will be lighter 1000 kilo with food and water compared 1090 for Exlex 2020 reason being she have no 138 kilo bronze plate and her bottom konstruction is much lighter. The near vertical chinerunners will take care of grounding forces. Stability she will get from water and batteries. The water I drink will be replaced by saltwater of wich there is a good supply. About twice a month the water in the jerrycans will be transfered to the 18 one liter bottles.
She will have pivoting centerboard instead of daggerboard, more easy to handle. She will have superior inner doors and many more improvements. Things are looking bright.
I now have two shots of vaccination. 18 March and 16 April. In a few weeks more time I have less risk of Corona. Then I try to fly to Porto Santo Madeira to do a summer sailing in the Atlantic going nowhere particular just floting around enjoing the deep blue endless eternal sea. When food and water is getting low I will head for Horta Azores with the plan to ship the boat to Sweden.
September 2021 I plan to continue the prototype, hopefully having it fit for sailing summer 2022. September. 2022 I intend to start the real composite boat. Work carefully taking my time sailing the prototype in the summers incorporating knowledge gained in the real product.
Stovage is not a very exciting subject, but a small cruiser with the stovage problem well solved is not very exciting in a storm and that is desirable.
A place for every thing and every thing in its place is a question of details, hundreds of details and to secure everything takes time so progress is not very fast.
This boat is a mockup a prototype so some may ask why go into all the details. I say there is always interference. There is always something unforeseen turning up and destrying the best made plans.
Stovage is a subject I will come back to again and again. Good stovage is essential for a seaworthy offshore boat.
Blow is a video about my arrangement.

Exlex of 2018 and 2020 had daggerboads. They are simple to make but more complicated to control remotly with lines. On Amphibie Bris 15 feet long of 1989 I used a bow centerboard. I sailed her from France to Newfoundland. It worked well.
Now I try again. I like to have one line pulling the board up and one line pulling her down. The problem is to avoid that the lines interfer with each other or get jammed. The bigger angle the centerbord is tuned the bigger the problem. To get much useful lateral area I like to turn the centerboard down about 80°. Large lateral area is very useful when slowly forereaching into a gale. I prefer that method to heaving to. You can make some slow progress to windward in comfort.
The centerboard case is open at the deck. That way it is possible arrange with a lever to move the centerboard in the unlikely event of the lines breaking. I will use oversize lines. 16 or 18 mm or something like that. Big diameter lines are also less likely to get jammed between the centerboard and the centerboard case.
By being able to turn the centerboard with levers I can attach new controlling lines. Exactly how it is going to be done I have to work out but I have some Ideas. It will be more easy to see as work progres.
