I give you the Nacra A3, the Melvin designed and built A cat marketed by Nacra. If the A cats can do it with their low numbers but dedicated A cat sailors, then the F16's can do it too, if they want to.
BTW, while Nacra has come out with about 3 different F18's in the last 3 years, Hobie is still selling the same old Tiger and doing quite well with it.
