You probably lose a few mph but the ride is much better. Going from our 26 ultra to the f30( which has the same bottom as f29) there is a noticable difference in ride quality. We can handle much rougher water with easeI have to ask, what kind of speeds do think that would run? I mean my Mach 26 is fun w/twin 300x's but I would think @ 29' it would be boring... I might be wrong though.
