[C320-list] 1995 C320 Buyer Information Requested

[bruceheyman at cox.net]

Larry,
On my previous boat I repaired 1200 very small blisters and then applied a barrier coat.  I did the work myself partly because I'm cheap and partly because I'd heard so many horror stories where it was not done right.
 
Interlux 2001/2001E is a great product but you have to follow the instructions and I've been in quite a few yards where they don't seem to follow them.  In addition to doing the right prep and washing with the right solvents to insure a great first coat bond you have to follow strict re-coat times.  They are based on the current temperature but generally are in the range of 13-22 hours.  Failure to re-coat with in this window means you do not get the stronger and less permiable bonds associated with a chemical bond and must resand the entire hull and go for a mechanical bond.  In my case I applied seven coats and ended up sanding of most of the last coat which should have given me a barrier coat if about 12 mils.  While watching yards do work on other boats you will see the worker apply a coat on Friday, go home for the weekend and then apply the next coat on Monday with out sanding, not cool.

I agree with your logic of getting it done right sooner rather than later.  When the boat was surveyed for sale 6 years later the hull received a perfect report so it was a positive factor in the sale.

At the time I had a quote to do the blister repairs and apply the barrier coat of $15,000.  I spent just over $2,000 and a ton of personal time.

Good luck,
Bruce

Pat,

Sorry for the delay in answering - just returned from an extended business
trip overseas.

The blisters have appeared randomly distributed from stem to stern and port
to starboard.  Some are at the waterline and some are along the bottom fore
and aft centerline.  I have tried to look for a pattern but have not picked
one out.

What makes these blisters somewhat different is that they are rather large,
but few in number.  Think of slicing off 1/4 to 1/3 of a tennis ball, and
you will get the approximate picture.

Every time the bottom is repainted I have to repair 10-15 of these.  They
didn't show up until WindSwept was about 5 years old, but are now appear at
each bottom job.

A talked to Peter a few years ago about the problem and his experience is
similar, as is his hull number.

It is probably worth noting that both Peter and I sail in very warm salt
water environments.  He is in south Florida if memory serves me correctly
and I sail around Corpus Christi, TX which is very south along the Texas
Gulf Coast.  In the summer water temperature exceeds 85 degrees for 3-4
months, peaking at about 88 degrees.

When the problem first arose, Catalina contributed some money for the first
blister fix since it was still covered by warrantee.

These early Catalinas were not built with the blister resistant resins that
are used now.  Instead they had a barrier coating applied at the factory.  I
am thinking that the barrier coating may have been damaged during an early
bottom painting job, perhaps even the first one during commissioning by the
local dealer.

At the factory tour during the Catalina rendezvous a few years back, Gerry
Douglas recommended to me that the barrier coating should be renewed after
around 10 years.  WindSwept is now about 13 and I may do that this year, but
when I review the problem with the boatyard that does my work, and an
independent marine surveyor the advice is redoing the barrier coating is not
worth the cost with this type of blister.  The advice has always been if the
blister is repaired correctly with vinyl ester resin there is no degradation
to the structural integrity of the hull.

My main reason for repairing the blisters is that I will sell WindSwept some
day.  I would expect a prospective buyer will discount the price they will
pay because of the blisters, so why not pay the bill myself now and avoid
the recurring repairs that are inevitable at each bottom job.

Larry
WindSwept C320 #246
