I dunno, I drive a 42 foot ferry which is enclosed for about 26 feet with TONS of windage, but it hardly ever gets blown around on me. Granted, I plan things out so that I use the wind to my advantage when landing, but it seems like it never gets too wild. Do you think that hull shape has something to do with this? It's a "built-down" (wineglass shaped) Maine Lobsterboat hull with a skeg that goes down 5 feet.
