A boat designed by Yrvind is extreme in all ways. First it´s very small and it should handle extremely rough conditions. It should be safe and provide protection for its crew. It should carry heavy load and should be able to sail in any weather conditions.
On top of that it should survive a rollover. A challenge for Yrvind was to find a sailmaker who understood his requirements and that is also a good interlocutor.

In this film Yrvind meets the guys at Hamel Sails. The film also shows how a sail is made. If you have a fast internet connection, you can view the movie in full screen HD, 720p.

Last weekend I visit Sven to se how his boat project advanced. I had my little camera with me and in this film you can se the results, Sven demonstrated how some parts of the boat is working.

To get an idea how the rig will set up and to figure out the sheet leads, I asked and got permission of my kind neighbour Logpart, to move the boat into their place.
I attached eight small wheels to a pellet and put the boat on the pellet. She moved along nicely. It was the first time I saw the boat from a distance longer than about three meters. I liked what I saw. She will be a good boat.

I put up the mast. At first there was some confusion with all the ropes but I soon got the grips on it.
The rig is special in that it is stayed but got no standing rigging. It is a bit like a windsurfer mast. It can move around and it has al those advantages. Instead of holding the mast with my hands I use running rigging. The mast has a wing section and is rotating. In addition to that if I lean the mast to windward the boat will get a lee helm if I lean the mast to the lee the boat gets weather helm.
As all the shrouds are movable there will be no chafe sailing downwind. The lee shroud can be slacked after setting up a backstay and the boom can be let out 120 degrees making it more course stable and less likely to gybe. Instead of a spinnaker pole fitting there as an extra gooseneck and its toggle can easily be removed to save windage on a beat. I have a long and a short boom, a long and a short wisker pole for different wind strengths and the can easily be changed without leaving the cockpit.
My sponsor Göran Marström the Olympic Tornado Medallist, came and had a look. He did not object even if it was not his way of doing things. My boat is way to slow for him.
To be continued?

In strong winds the dorade box is the first line of defense against water trying to enter the ventilation systen.
It should have a big volume be deep have a small inlet and a big drain. To prevent the incoming air going out the drain instead of coming into the living area I use a U-tube, familiar from the common verity of WC where it prevents bad smells from entering the house.

The picture of the finished doradebox shows that the boat is now also painted on the inside. The black handhold from the corner of the box also functions to prevent my delicate head from hitting the corner.

In Archive July 2008 I describe how the rest of my heavy weather ventilation system prevents water from entering the boat even if its upside down.

Above. The frame for the hatch to the bedroom is getting in place.

Below. With the hatch on I will always be snug and warm in my bed. The theory is as long as I am comfortable and nothing breaks I can survive anything.

Above. I start with temporary attaching the grab rail with several wooden pieces screwed into the laminate and a piece of string. When the grab rail is in the desired position I remove half of the temporary pieces and replace them with high density (425 kg per cubic meter divinycell pieces shown to the right of the wood piece)

Below. I the lash with carbon filament unidirectional glass to get it into position. The ends are cowered with 45 degree glass cloth. The I use NM-Epoxy as glue covering it with peal ply to get a nice finish. Then I replace the temporarily wooden pieces with Divinycell and repeat the process wich is time consuming but gives very satisfactory result.
