Looking at an Oday 27, 1977. Boat is in amazing shape on deck, riggings, interior, engine has only 500 hours and seems brand new, in fact the whole boat seems new. Only problem is I can feel 2 to 3 small blisters on the bottom reaching down over a three square foot area(Only area I felt). Love the look and feel of this boat, but do not want to have a consistent headache. Would not consider boat if not for the excellent condition of the rest of boat (Best I have looked at by far). Going out of water for survey on Wednesday. Looking for advice, or past experiences from other owners of Oday sailboats. Willing to pay to have problem fixed to a certain extent, but I believe the boat woiuld have to be dryed for an extended period of time (Meaning no sailing) or am I mistaken. Please Advise! Mark
