On a different note - when the UFO wasn't foiling, how fast was it? It's a cool idea, but from a quick look it's hard to see it being quick in light stuff, since once off the foils it is basically a very short cat.
I would almost guess they'd be about the same speed as a non-planing windsurfer of the same length? Maybe a bit slower depending on the sail size?
I would ask if the boat can sail a W/L course without foiling or would it be better served with a triangular course like the non-spin boats?
But that price-point and ease of use certainly gets my attention. How hard is it to foil? Is it constant weight/sail/tiller movement like the Wazp or A-foiler?
