[C320-list] Anti Blister protection

[Bruce Heyman]

Adam,
Do you know if they were in the laminate or just in the gel coat?  If the
bill was only $1000 it sounds like no fiberglass was involved.

Hull 218 had some blisters last haul out.  If the yard could repair them
all for under $1000 they couldn't have been that bad (and yes I saw them
before the repair job.)

Warmest Blister Free Bottom Regards,

Adam

Stephane,

Some years prior to your build date Catalina started using a layer of
vinylester resin in the hull to prevent blisters. Like you, I have a
1998, and I don't have any blisters. None of the same era or newer
Catalinas in the yard seem to have any problem with blistering.

It'll be interesting to see if we get a variety of opinions on this
topic. Mine is that without a barrier coat you might get a few blisters,
but they are easy to repair.

Around here we have to haul out annually, and if we find a few blisters
we chip out the area, let it dry, and fill it. It would take much more
effort and expense to apply a barrier coat or deal with a contractor who
might or might not do a good job applying it. I've seen a few examples
where a supposedly well-prepped hull had a barrier coat applied, and it
did not adhere properly. I've also seen problems where supposedly
compatible anti-fouling paint did not adhere to the barrier coat. Either
case presents you with an expensive and time consuming mess. Finally,
when you need to repair chips and scratches on your hull, and possibly
some gelcoat crazing, the barrier coat is just one more layer that has
to be removed.

  Mine is a 1994 and has never had a single blister. Not sure about
later 
  years, but i'm sure others on this list will respond.
