I am working on a Flying Scot that I bought last Fall. The rudder is made of 2 pieces of wood with a thinner piece sandwihiched between them. My boat #436 is from the 60's. I don't know specific year yet. My question is what type of wood should I put in the middle? I think the outer pieces are Mahogany but I'm not 100% on that. I will try to include pictures but I have been having difficulty uploading them.
