while watching the great video above

I have to say that this came into my mind:

Found this on another site.....

with that huge mainsail I can Imagin that the behaviour in the picture above is the failure mode number 1.

I've build RC boats too, one of which a cat and this happens so easily. Even more than on any beach or racing cat.

Do the foils solve the problem?

I have no idea and I'm just that guy behind the computer, but from what I've seen I'd cut down the top of that mainsail by quite a bit. In the video the top third of the sail was not activa anyway. In 6 knots of breez.

Thanks. More testing and refinement of the i-flap and ama UptiP foil that worked so well today. It is 100% different than any current UptiP foil and the i-flap is perfect for lite air takeoff on a trimaran. It works like a wand controlled flap does on a t-foil-except it does it with no moving parts!

 

no moving parts? how does that work?

nice!

huge mainsail... that sure is a light wind rig!

Getting this right on a radio conrolled boat is very difficult because you arn't actually sitting on it and feeling things happen. Thats a completley different story! The system needs to be very robust for a stable flight like that as there is no world class sailor on there pulling the strings. There is only one observer.

Looks great!

how big is this thing? 2 meters?

do you have an active control on the centerboard flap or a passive rod-system moth-style?

the rudder seems quite large, but still you problems tacking. I'm not sure how this all scales but on bigger boats this sure seems to work better!
