The pic is of a rudder shoe from another Pearson. I never saw the boat so I don't know if the rudder post was stainless or not. Obviously this could be made to work but is it a good idea?
If the stainless was more noble than the rudder post and caused the post to disappear my "free" shoe would be the worst bargain I've ever made. And there is some stiff competition for that title.
Another option would be an insert of some material like teflon that would separate the two metals. If I tied the tiller so the rudder did not swing with every wave it might last awhile but how long?
Any ideas?
