At 22 April I became 80 years old.
I am glad for that. During the past 80 years I have experienced a lot made a lot of mistakes and learnt a lot. The coming decade I will profit from that.
At an age of 80+ when most persons have stopped doing daring deeds I will go for a world record, a first. I plan to make an ocean passage in a yellow centerboard schooner rigged with balanced lugsails. The boat will be less than twenty feet with a draft less than one foot and there will be no selfstearing or autopilot. Also I will do it single handed unless a brave, petite girl will join the crew. That however will not make the venture less daring on the contrary. Will I succeed in this most difficult task? With your support my chances will increase so please use the donate button or Swish to 0706200550.
Help me make this new decade a great one for simple boats and simple life. Making a better world for us all.
This is a video of the idea of the daggerboard.
It is placed foreward of the saloon/sleepingroom therefore it does not to any great extent interfere with living conditions.
When lowered there is space in the daggerboard case for the top of the daggerboard to mowe foreward thuse the bottom part can mowe aft creating the same effect as an crumple zone in a car. On the wind Exlex might mowe with 3 knots or 5 km an houer compared to 1oo for a car still the crumple zone about the same lenght.
Enjoy, regards Yrvind
He ask if it is not better to have more dense material in rudder and centerboard as not to stability due to flotation.
Heavier materials low down will give more stability. Added lead will give even more stability. In the case of the centerboard, when the board is raised, more weight will make the boat lose stability.
Almost every boat is designed as if it was to be a racing boat and the same with books about yacht design. Exlex is intended for cruising, when cruising I sail mostly down wind, even though I plan to round Cape Horn, 50° south to 50° south, east to west. Exlex is designed as a low energy boat and cruise at low Froude numbers around 0.3 this reduces the energy needed to about 1/6 of a conventional boat. See my Manifesto for a more detailed explanation.
More weight in the appendices will put more strain on them; they have to be designed more heavily. This added weight would make the boat slower down wind. It will also make the boat bigger and heavier and more expensive.
I think most boats are sub optimized for windward work. Neither do I think a cruising boat shall have weather helm.
I have done more mock up, now in the saloon. I now have a pretty good idea of the finished boat. Exlex Minor have turned out very roomy despite being only 4 cm longer and 19 cm vider than Exlex that was indeed very cramped. Exlex Minor have definitely place for two persons friendly persons to cruise long distances a boy and a girl.
Edition Paulsen did 11 of October publish a book titled 100 Marin. Its a selection of famous yachtsmen from the last 150 years including Jules Verne, Bernard Moitessier, Francis Chichester, Jack London, Naomi James plus 94 other equally famous person and me. Its a mystery how I got included, but I am proud to be included in that crowd.
Below are some pictures click on them once or twice to enlarge.
I have started to build up the hullside from the stern. Two sheets on each side are now in place. Aft is the easy part, like building a box. Simple structure, but nothing is gained by making it more complicated.
Below two pictures.
First placing the Divinycell in a good position. Important when you are working alone. Adding the NM-epoxy. Clamping it on trying to get as good a fit as possible.
I am now building up the mould. The plywood has to be faired to fit. First I do a rough fit with the help of a spline and some lead weights of the sides. After that the bottom sheets is put on. Now I am fairing with surfaces instead of lines. That is far easier.
The aft part of Exlex is ready for the Divinycell. The spoon bow will be much more difficult to get a good shape on. I will take my time to do good work on that.
Below some pictures.
First me with one of my favorite splines. I have had it for many years and faired many boats with its help.
Below a close up of the same spline or batten.
Below, aft end of Exlex ready to take the Divinycell sheets after first being insulated with plastic film to prevent them from sticking to the mould from epoxy that finds its way there.
