After more than six years, my boat is finally sailing. I think it looks good.

I have a question for you Luiz. But first let me say that I am thoroughly impressed with your creation! Hope you have a great time sailing that beauty. Ok, so in picture 2, it just looks very odd to me seeing the daggerboard so far forward. I am not very familiar with the physics of this, so what are the advantages of having the board more forward or more aft? thanks

NICE.That's gorgeous. I've got an old Trailer Tri 720 that I've been working on for awhile. I can't seem to stay ahead of the repair work. After 6 years you must be one happy camper.

That's great!!! Congrats.

It seems to sit really high in the water. Is it running on it's designed water line?

I hope it turns out to be everything you hoped for.

Much admiration for see a project like this through.

The boards are forward and angled to provide a certain amount of lift for the leeward ama. Not enough to be a true foiler, but enough to keep the bows from stuffing and the ama from generating a lot of drag from being submerged. Check out the video link that was posted, check out the banana boards forward on the amas. Then look at how the lee ama is not submerging - same idea here.

Biggest Congrats on "the end of the beginning" to your relationship with your Catri <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

Here's to many exciting times ahead.

The daggerboards (bruce foils, actually) are displaced forward in order to increase dynamic stability. The center of lateral effort is kept in place because only their vertical projection counts, so it is effectively smaller, and the rudder is big. Bill Roberts also did something similar in the ARC 21 and calls it "shared lift".

I have not weighted it yet, but it seems to be sailing in its lines. There is no carbon at all in the boat.

Are you talking about board position or that high trapping position? <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
