My own experience with a wing keel
Bob,I have a C22 wing keel and have sailed a few times on some older models with swing keels. Obviously, the difference in draft affects the ease/difficulty of launching/retrieving. In my case the lakes I use are also used by much larger boats, so the ramps are designed to accomodate really deep draft.Aside from having to bury the trailer a little deeper down the ramp, my opinion is that the wing keel models are a little easier to launch and retrieve. The OEM trailer has a gate/guide that makes alignment almost idiotproof. Not true with a swing keel - you have to get the alignment pretty close or you will miss the rubber support for the swing keel.I feel that the wing keel makes my 22 slightly more tender than one with a swing keel, although this is hard to quantify. On the other hand, I'm not a racer and am a pretty conservative sailor.Having a wing keel does simplify the maintenance since a large fraction of these issues are concerned with swing keel maintenance (judging by posts to the C22 maillist). It does make launching and retrieval a bit more difficult. Most of the folks that I know that have wing keel models keep them in a slip. If I wanted to trailer more often, I would probably opt for a swing keel model though. But having a boat in a slip is so much nicer than having to launch every time I go sailing.I think the biggest question to ask is how much do you intend to trailer the boat. Good Luck,Dave in Denver
