These are not rudder T foils.
From the photo's it is a little deceptive as to their scale. These are symmetrical hydrofoils and the actual blades on them are almost twice as long as the rudder T foils. Although the mechanism for connection to an “angle of attack wand” isn't in these photos, they will be automatically controlled in a similar way to the foil on the moth. The object is to foil with them approximately 6" clear of the water surface. I am working on a case for them so that they can be fitted in the same way as dagger boards and also with a bracket so that they could be fitted to any hull.
As for their first use I am in the process of finishing the plug from which to make the mouldings for a tri maran using the Alpha Omega F14 hull as the centre hull and two smaller ama’s.
