a fix or a sign of future problems

[l_lym]

Came across a listing of an 85 Westwind 38 with the following note:

"In 2007 the whole of the bottom was stripped and gel coat removed, the hull was dried out and refinished with 2 coats of Interlux eglass, then 830 fairing compound, 4 coats 2000e expoxy barrier then 2 coats Interlux antifouling, this was all professionally done with no expense spared. "

I'd be curious to hear opinions on whether there would be risk of future problems or if this level of work should be considered completely positive. Also any comments on the Westwind 38 which had not been on my radar screen.

That is fairly common treatment for osmotic blisters,
and was likely a very expensive process. It should
prevent the problem from returning.

It all depends on the quality of the yard or how well the original owner did the work. Properly done, a bottom job like that will really take care of true osmotic blisters. Its to note that not all blisters were osmotic. Especially true of oil embargo era boats, (not this vintage) some blisters were due to chemical addins or substitutes to resin that never really "kicked" fully...and weep out and eventually cause blisters. Those are usually all over the hull including topsides as well as hull...and typically worse in warmer waters.

Read about Valiant 40s of the late 70s for info on non-osmotic blister boats. Wowza.

It also depends on whether the hull was properly dried out before applying the barrier coating. Barrier coating a wet hull is going to lead to problems, usually taking a while before they manifest...
