From what I gather, the "V" shape of the dagger board foils helps to stablize flight. That is slower means more lift because more of the foil is submerged and faster menas less lift, because more of the foil is elevated above the waterline.

Due to the different pitch produced by the forward part of the boat being lifted higher or lower, that has a direct affect on the pitch of the flat foils on the rudder bottoms.

Pretty ingenious and simple, compared to other designs I've seen.

With all that said, I believe you are right; one doesn't start foiling and leave everything else up to Otto the autopilot.

It will be fun to see how it all works when the first proto-type rolls off the production line and splashes for its sea trials.

All I can say is "waaahooo".

Here's a video of the gunboat wiping out. So much for grabbing a sandwich while foiling.

The most stable foiler I"ve seen is the Hobie TriFoiler but I still haven't seen many on recreational Saturdays.

Here's some videos:

Even they don't always work right.
