Re: Is external rudder a good idea?
I had a rudder split a few miles offshore. (I had just gotten the boat, and there was obviously some damage which had occurred when the previous owner had it. He told me he had hit a rock but I did not see any damage when I looked at it.) I pulled my rudder into the cockpit, shot some screws through braces, and put the thing back on.
That's tough to do without a transom-hung rudder.
