up or down
The mechanical engineer I purchased my 1982 C22 from was convinced that up and locked is better.The nice folks at Catalina Direct said no, keep it down, since all that weight down low, keeps it more stable.As far as a test, my wife and I found that, when she's below, she gets jounced around much more when I step off the boat with the keel up, than when we have it down. So we think down is more stable. Having said THAT, I'm sure wiser folks than I will tell you that keeping this swing keel boat in salt water is incredibly corrosive. But if it's your only option...
