What started as a minor gelcoat damage repair of bow damage on my '79 27' O'Day has turned into a major project. While the repairer was stripping years of bottom paint off he discovered the trailing edge of the keel was splitting / delaminating from the bottom up--about 15 vertical inches of damage. It appears the prior owner may have covered up a problem with Bondo and a lot of paint and sold the boat to me in mid-2007. I noticed when we hauled last winter that the keel seemed to be "weeping"--that it appeared to have a wet area along the bottom. Turns out the keel has a lot of wood filler (now wet and rotting) beneath the Bondo, starting from the trailing edge andmoving forward for 18" or more (he's exposed about 18", perhaps more to come) and tapering down from 15" at the rear to maybe 7" a foot forward. Does anybody know whether wood might have been used by O'Day during manufacture in 1979? The repairer states categorically he has never encountered wood in a fiberglass keel and that use of it is prohibited in any shop in which he has worked--you build up fiberglass with standard filller material, not with wood under the waterline.
