I am buying a 1978 OD-23-II. It has no trailer. The mast blew over in a wind. The screws pulled out of the deck. I understand the wood inside the deck is likely rotten. I have bought a used trailer but need to know how high to set the bunks and rails above the keel, so to keep the weight properly distributed. I cannot find any specifics on the internet. Was hoping to find someone who has an OD-23 with trailer who can take some measurements and send them to me. Can also call me directly as I do not check my internet often. Cell phone 850-207-0291. I am in Florida and hope to pick up the boat this Friday. Just need some measurements. From reading other forum posts, I understand most of the weight needs to be on the keel. So need to know how high and wide to set my bunk rails for wooden rails.
