I purchased my boat a couple years ago which I thought was an 1976 Oday 27.Thinking of moving the boat to a closer marina which is very draft restricted. My boat definitely has a centerboard but unable to locate any info on an Oday 27 from that year with a centerboard. Supposedly the 272s were manufactured 10 years later with the centerboard feature.What I really need to know is how much water does the boat draw. What I would like to know is what model do I own?Thanks for any helpWayne
