Evening Guys, New member here. I just bought a C&C 25 MK1 from an owner who frequented this mailing list, who told me about this forum. What a great resource! I searched the archives however and could not find the answer to the questions I'm about to ask. Here goes.
My transom hung rudder has a serious blister problem not helped by an old leaky lower gudgeon. This leak was patched by the previous owner with Gflex however the rudder was not opened for inspection or dried out. I'm away from the boat for the next week and I'd like to get ahead by ordering what I need now to fix the rudder when I get back to the boat. I haven't been able to find any diagrams or pictures of the rudder construction on the 25 MK1. I've read that there is a piece of plywood somewhere in the core and other posts that lead me to believe that below the waterline portion is hollow, and that some have drain holes and some don't. Does anyone have better information on the construction of this rudder? I want to know because if I can safely rebuild the rudder out of some polyurethane foam I will. I've had experience with this in the past repairing another rudder damaged by grounding and it turned out extremely strong and more rot resistant. But this was for a boat with a foam filled rudder originally, so I don't know if the skeletal structure of the rudder on the 25's would support this. Anyone have suggestions on what route to take? It'd be great if someone having done this could go over what route they took. Or if foam is at all advisable. I also don't want to upset the balance of the boat if the original rudder structure with that hollow was an integral part of it. And I know that I could order a new rudder from South Shore Yachts, but I'm guessing that's expensive. And ofcourse way less fun. Many Thanks, Ian Tubby 1976 C&C 25 Mk1 "Icicle" St. Petersburg, FL
