About that C-25 swing keel...
Alex,The Catalina 25's swing keel weighs about 1,500 pounds, and there is no lock down pin. Some of the older ones may have developed excess pivot clearance leading to keel clunk. This can be remedied by installing a pivot bushing, new pivot pin, and maybe some shims. The C-25 wing keels are not known for their windward pointing ability; the swing keels are. The wing keel itself (not counting the rudder!) draws a couple more inches than a raised swing keel, so trailering and launching should be similar. If you run aground with a lowered swing keel, just crank it up a bit and go. If you run aground with a wing keel there's no crank, and heeling it over further isn't going to help like it would with a fin -- the wing just digs in deeper. I like swing keels!
