One of my rowing buddies is Eric Goetz who own Goetz Boats. He builds world-class yachts and is as honest as the day is long. Perhaps someone on the Governing Board could contact him about replacement rudders. I mentioned it to him and he said he would be willing to discuss this issue with someone. Here's his contact info:
