My friend has an O'Day prototype,from 1969/1970 (we think). It is about 5' 6" long, can hold two adults and two kids max, placing your feet into a center section and sitting on the rim. It has a blue fiberglass top with white underneath and the mast/boom are gold-bronze in color. Anyone out there old enough to remember this one? We are trying to locate the part that holds the boom in place, allowing the boom to swivel. (Is that called a boom bail?) The original equipment snapped, a white plastic of some kind. Sorry. we have no ID or model numbers or paperwork. The boat was inherited. Any ideas as to what is out there to replace this item? I am not a sailer. I just happen have the time to do the web search. This is a small, fantastic sailboat. I would love to help my friend find the part so her family can use it again. We are also looking for hallyard clasps.
