.. a bit eccentric?

I am hankering for a project over winter, if for no other reason than to, again, put off painting the house.

I have built a 22 foot by 22 inch double and would like to ad a sailing rig (as per the Tassie paddlers) but think that my boat is too unstable to take any real wind load.

So… I then thought about a mini trimaran with two narrow outriggers, but that would mean designing and stripping two outrigger hulls, which would mean lots and lots of time, all for soemthing that may not work.

What about an outrigger system that relies on “Flyak” style foils to give the lift? The flyak system gives at least 90kg of lift at say 9 knots, which is heaps for what I am after.

The advantages are:

1. I can claim to be working on something unique, which gives me a better chance of avoiding the painting.
2. I can get away with one cross sectionional piece, not two.
3. It will (I think) work better at the speed increases.
4. The vertical section (going down to the foil) may act as the keel?

The downsides are (at least)

1. I haven’t the faintest idea on how to design a foil.
2. It may look stupid.
3. If I go too fast and pitch pole the boat, my partner will not go out with me again. Or perhaps more soberly, am confident that a trimaran will work, but am not at all confident at this idea.
4. It may well not work well in the open ocean. That could also be said of the displacement version of the trimaran.

What do y’all think? Can anyone point me to saiboat design websites? And, does anyone know of a foil design program that covers blade area, shape, pitch, and drag at various speeds?

Cheers,

Matt
