I appreciate your comments.

There are so many that contribute to those of us interested in
sailing. From their cruising logs and well thought out practical
experience to restorations. The time and effort those people put into
their contribution is so great it does make a difference.

Interesting material. However, I intend to re-start the debate over
the effects of blisters. Can anybody find any examples of hull failure
due to normal blisters? I maintain that such blisters are at worst a
cosmetic problem that are ussually hidden under water. I have seen a
web site that says 80% of all blister repairs, even by gelcoat peeling
are failures.

http://www.hotvac.com/process/default.aspx

"HotVac treats boats by…

* The thorough removal of absorbed water from affected hulls.
* The removal of acids, glycols and other organic compounds that
cause corrosion, glass to resin bond weakening, delamination and
blistering. "

Fiberglass Blisters
Effective prevention and treatment

"The hull must then be dried, to get the saturation of the laminate
below 50 percent, which can take considerable time, as reflected by
the following table:

Temperature 50% Relative Humidity 25% Relative Humidity
100 F l6 days 9 days
83 F 32 days 18 days
65 F 64 days 36 days
47 F 128 days 72 days"

I dont have the reference handy but the amount of water a hull can
absorb is quite significant, and yet not have any ill effects although
not universal. I guess some of the issue is where the boat is
seasonally hauled out and whether it is fresh or salt water...
