As probably the only person on this forum who has direct experience with winged keels dating back to 1989, I have to say that wings get a bad rap from most people. I've owned 2 boats with wings (both Pearsons, currently own a P-33-2) and here's my experience with them. Because of their very shoal draft, you won't be running aground much anyway, and when you do, the keel tends to bounce at first and not dig in the way a fin or bulb would. Thus, you have a chance to steer for deeper water right away.
BTW, I sail out of the Patapsco River and have gunkholed all over the northern Chesapeake.
