LEEBOARD

Boat ideal will have leeboard. Thinking aboat leeboard has changed my mind. I have decided to have leeboard on Yrvind Ten also. Ocean going boats do not have leeboard, but traditionally ocean going boats are big structures and lika all structures subject to Gallileos square cube law. Becouse of the square cube law a small boat do not have to be simular to a big one. In fact its a big mistake to build a small boat simular to a big one. Its against the laws of nature. Bugs understand that. They to smart to try to imitate vertibrates. Each one to its own scale.

The present project will then teach me much about them. Good for the next boat. The upcoming circumnavigation will be a lot of down wind sailing. Thats were leeboards excel. Downwind a keel is really bad a centerboard better but there is still the slot causing turbulence. Then the control ropes. Traditionally there is only one rope, an uphaul. but if the boat is going to be capsize-proof you need also a down-haul to control the board in all positions. For piece of mind. I have not got these mechanism to work to my satisfaction. This is not the first time I change my mind regarding centerboards. Bris had one to beginn with Yrvind.com started with a centerboard, then a daggerboard I scarped boath of them. Centerboard worked fine for me on Bris- Amphibie, a daggerboard worked fine for me on Duga.

Leebards will also give me much more space in the saloon.

I am avare that leeboards have its own sets of problem. I will try to solve them later.
