Hello all. I recently purchased a 1977 O'Day 25. I did this after sailing a grand total of 3 times (Hobie Cat in Plycar,MX, a Hunter 36 and a test cruse on the O'Day). I actually looked at several boats from 14 feet on up. My 25 has been well maintained. Sailing has been interesting(my biggest mistake was to take my wife and two kids out the first weekend we had the boat - nervous, mad, hot and scared were just a few of my emotions not to mention my families.) They forgave me and all is well. Before and after purchasing my boat I have read, watched dvds and done lots of research on this website. My question is about removing and inspecting underneath the chain plates. Please remember I am a "newbie" so forgive me if the questions are to basic. 1)Once you loosen the shrouds(I assume you completely detach them from the chain plate) what do you do to support the mast? I will be inspecting with the boat in the water(is this possible/advisable). 2) Is this a one man job or two. I know the bolts in the bulk head can be handled by one man but wonder about the deck plate bolts.3)Assuming the bulkheads are OK, what type of sealant should be used when reassembling everything. If bulkheads aren't OK what epoxy should I use. What am I forgetting? I did purchase Casey's book "this old boat" but it dosn't talk about boat specific stuff. Thanks to all.Scott
