I'm looking at purchasing a used O'Day 22. It needs some TLC but I don't mind that. I confident that I can look after the fibreglass work but I'm concerned about the mast. Looking at the area around the spreaders there is a row of rivets extending up and down both sides. I assume this is how the spreaders are mounted. (Right?) The leading edge of the mast appears to have either a seam or crack at the spreaders. Is this something to be concerned about or is this mast constructed in two sections?I did some sailing years ago and would like to get into it again. I dson't mind taking on a boat that needs some work but don't want to get in over my head.Cheers,Don
