O'Day Parts Guru
The guy to start with is Rudy Nickerson at D&R Marine in Assonet, Mass. If you have spent any time on this site, you know that Rudy is the go to guy for parts, plans, etc. for O'Days. I have spoken to him and he is very helpful and friendly. He told me that he has the molds for most O'Day parts, and could probably make a new centerboard for you. No computer as far as I can tell, but his address is P.O. Box 921, Assonet, MA 02702. His phone is (508) 644-3001. You might also want to search this site for threads on centerboards; there have been quite a few and someone may have already asked your question. I have a '79 O'Day 23 and am very happy with the boat, and have used this site several times to correspond with fellow owners. Good luck, and welcome to the club.
