i am in the process of buying a bcc. the survey was done yesterday
and the only major flaw was the rudder. it had previously developed a
split along the aft edge and taken water into the core. the owner
drilled holes in it and drained it, bringing the weight down from 110
lb to 100, then fiberglassed the aft edge. it had been previously
barrier coated (the hull had moisture readings near zero) but there was
some alligatoring of the epoxy on the rudder only. the survey revealed
very high moisture content in the laminate below but not above the
waterline, as well as 2 or 3 areas approximately 6 inches or greater in
diameter where the fiberglass skin had internal delamination (not just
debonding from the core).
i am seeking advice as to how to proceed. one option would be to
strip the rudder down, grind out the delaminated areas and rebuild it
with new layers of glass then re-epoxy it. my concern is that it has
already been repaired once and i doubt the efficacy of actually
draining the water out of the core without actually cutting a big
window sized hole in the thing, which i guess would be another way to
proceed with the repair.
the other option is to completely replace the fiberglass portion of
the rudder and re-use the cheeks, etc. i spoke with roger olson who
gave me a price of around $1000 plus shipping for a new rudder.
has anyone else had a similar problem? how did you handle it? did
it work out ok? do people think that the core can be dried without
major surgery on the rudder. thanks in advance.

Mr, Churchill: I think the seller ought to contribute toward a new rudder
for you. Forget patching. Once wet, the gnawing fear of delamination when
you least need it is something $1,000 should easily address, particularly if
it becomes a contigency to the sale price.

I agree with Mr. Dion. Knock $1000 dollars off the sale price.
(I admit that I’m not a BBC owner yet, and therefore have a vested
interest in making this the established way of thinking.)

I think the only answer here is to replace the rudder regardless of
who pays for it. A reasonable seller would at least contribute to the
cause.
$1000 to keep the vessel and crew from potential harm is a small
investment.
As most of us know, there is alott of force on the rudder as we
counter weather helm when hard on the wind and alott of canvas up. It
is no place for weakness!
By the way. Which boat are you buying?
Good Luck,
Russ…
