I agree with your comments but the thing still is pretty neat.. pretty fast to go together as well...The mast has to be its weakest point...as you say way, way too flexible....nothing a little extra carbon couldn't remedy...lol...if they get up and going into production maybe they can convince one of the windsurfing mast builders to make one suitable to the righting moment of their little cat. shouldn't take much to accomplish that with filament winding technology.
