I wouldn't either, as long as you don't mind not pointing high and missing tacks because the boat won't come around, or hitting a transom or two because you couldn't quite duck somebody. Bird are more adapted to air than us, but I never saw a aircraft with feathers. After watching Flipper beat up on sharks (which haven't changed since the dinosaurs) I know which one I think is more evolved. Another example from the Bethwaite book, they spend a bunch of time towing hulls two at a time on this balance beam arrangement, comparing known performance hulls against experimental ones. After a road trip to a different location they couldn't reproduce some results until they realized that the test boat had gotten a layer of road dust on it that wouldn't come off in water (think spraying your car down without washing it, know how it leaves that film). After soaping and wiping the hull down, it was right back on their old numbers...with the 1000x greater density of water than air little turbulence adds up.
