I just purchased my first sailboat, a 1974 catalina 22.THe owner manual says nothing as to how to operate the swing keel, except to say if you turn the keel crank to hard you can damage the hull, and to stop when you feel resistance. Being almost 30 years old, it feels resistance anyway! My question is, which way does the crank turn to lower the keel, clockwise or counter clockwise? Any info would be appreciated. THank You!
