Most excellent build.

The big issue with twin main foils as I see it is induced drag at takeoff. You really want maximum span there. With two foils you get two more tip vortices than needed, and much more drag when you can least afford it.

The strut drag is significant, but with two struts the main foil can be so much higher aspect that it outweighs the loss from the struts, and the struts can be much smaller also. I suspect we may see twin strut moths at some point with the Clive system if the fairing drag can be worked out.

Invest in some good knee pads and shin guards.

Also take a look for and correct obvious sharp edges.

I came back in after a couple hours sailing to find a gash on my knee under the knee pad that required about 6 stitches! End of the carriage track was the culprit.

But, a single ride upwind in about 10-12 knot breeze will make you forget about the steep part of the learning curve...

Sorry about that. That carriage was a bit of a compromise between Gaudi-esque style, reduce/reuse/recycle, and death needles.
