Fiberglass hull and rudder problem

[Jeff_H]

I think that everyone has given you quite sound advice here. If the boat has been damaged sufficiently that you are looking at a 1 foot diameter concavity, the repair should have been done by a very competent yard using very high grade materials. If the repair is so poorly done that you can see crazing and a one foot diameter concavity the work was not performed by a yard that knew what it was doing.

With regard to boats from the 1980''s, the oil crisises were in the 1970''s. There was a general reformulation of resins in the 1970''s to produce them more efficiently. This most strongly affected boats from the mid 1970''s through the very early 1980''s. By 1985 the worst problems with osmotic blister resins had pretty much been sorted out. That said some manufacturers seemed to have had random problems or continued problems longer than others. In 1981 and 1982 Hunter had extremely bad blister problems but from what I can tell by the mid- 1980''s they had put that well behind them and were offering pretty long term blister warrentees.

I would have fixed the rudder, for less than a grand you could have reskinned it and had a better than new foil.
