A year ago we bought an 88 TR 30 Catalina with a wing keel[our first wing keel], and I would buy another. Our log shows we have sailed the boat over 70 times in open ocean. In general sailing, I forget it is a wing. We have no trouble staying with other boats in the 30 class, and beat some. Hard on the wind, a deep fin might go a small fraction higher,but I don't think a shallow fin will do any better. We dock in an area where we must have 4' or less draft, and the 3' 10" works great. I can't really comment on the problems from running aground, because we just don't go aground like we use to with 5' draft. It does make sense that the big flat wing would be more difficult. Leaning the boat over would not be effective, but turning it 180o would work as well as a fin and "go out the way you came in" Good luck and good sailing Ron B
