As I sort through all the items stolen from my boat (see other posts) I realize that the mast "crutch" was stolen as well. This was a cool item that had a metal pin that fit into the holes where the rudder attaches, and had a plastic "U" at the top to hold the rear of the mast (the front is in a crutch built into the trailer). Is this a stock part? It seemed to fit perfectly, would like to buy another rather than improvise. Anyone seen these? Thanks!
