Shouldn't there be a rule that says rudders have to be able to go through the surf?
Like in the spirit of being an of-the-beach catamaran?


Sounds like they are able to traverse the surf.

I haven't read this whole thread so maybe someone has thought of this but if the wings were allowed to rotate freely (sort of like a max prop) could you set a stop so that when the rudders are down the axis or rotation causes them to take the path of least resistance except that when bows go down X degrees the wings hit the stop, and then when rudders are kicked up they continue to take path of least resistance. This would seem to solve both the issue of light air drag and moving with rudders kicked up.

Except that the stop will stop them from moving in the direction that they need to move in order to reduce drag when kicked up.

After thinking about it the whole idea may be flawed and would add more complexity with very little benefit.

The only drawback I can establish with respect of the T-foil rudders as they are available now is traversing the surf. Ones that issue is solved then we'll all be sailing with them.

Kelp, kelp, KELP! It's a show-stopper for me.

That is doable, Some people are working on it.

Currently we are working on a setup that will unlock the T-foils when the rudder kick-up mechanism is unlocked (like when hitting something)

No.. The rules should NOT have such a clause.

Wouter,

That is exactly what the mechanism described in my previous posts does.

How do you display the attachment picture in the post?
