I did something similar in a foiling moth 15 years ago ( when I had hair )
A bow rudder linked with strings to the aft tiller and normal fixed blade.
All foils retractable.




It sort of worked Ok, but need a lot more development work. ( since done by Brett Burvill, John Ilett and others.)


Here's another early moth foiler ( Ian Ward AUS ) with canard config, using the same principle of controlled ventilation on the front foil as the tomohawk foiler.

My guess would be it's for assisted balancing a la bicycle when up on the foils. Well-used already in human-powered foiling boats.

What's the benefit of a bow rudder? The only reason i can thing of is, it allows them to have the main foils further back. But there must be a better, more complicated reason

Even if it takes a small performance penalty in a one design it would be a better solution. I suppose I shouldn't be suprised that FB is smarter than I am!


A heck of a lot more robust- if you look at the picture of it on land,it is supported only by the foils only whilst someone (if I picked up from SA right, Julian's son) is standing on the boat.

Apparently the stern rudder is just for launching and low speed handling: they hope to eliminate it completely.

According to JulianB on SA Frank B did 75% of the work including building and wet sanding the foil arrays... I'd like to hope I'd be capable of doing that sort of work at nearly 89...

Now you mention it, yes. Didn't look that big at a glance, and something about the post made me think singlehander (Ian! )

49er isn't it?
