Re: Looked at a Valiant 40 Today

We own one of the "blister boats" and had the blister repair job done, but some of the blisters came back. Just little ones, but annoying. In the overall scheme of things, though, our old Valiant40 has been a fabulous boat for us for 26 years. We sail the British Columbia coast and this boat has taken everything nature could throw at her and then some. Sometimes she comes out better than we do! We have hit our share of rocks over the years (6, I think at last count) and she never needed anything more than a quick repair of the leading edge of the keel. Built like a brick. She holds endless memories for us and I love our boat! Yes, the small blisters are annoying and I know off-putting to some. But this is a true sea boat and I trust her completely.

Nice boat mitiempo. I'll give it some thought.

Thanks, Bill

This might be a good boat for you. It is well equipped, overbuilt, and in good condition. Crealock « Southbound Solar

Re: Looked at a Valiant 40 Today

Hi all, thanks for the great replies. For the record, I do not intend to EVER own two boats at the same time (been there, done that ).

Simon, at the risk of igniting a major fire, I am considering keeping my C36 and making the trip with it. I have heard from others as well that C36s are popular in Oz. They only get there one way - on their hulls! So, I know it is possible.

In the mean time, the search goes on. I am quite enjoying looking at other boats and seeing what is out there.

Thanks again, Bill

SimonV Bill, the boat you have is a well known boat here in Oz, I have a couple of friends that bought C36s after they crossed the puddle and landed in Oz. Going back the way you came is tough and for that direction you will need a blue water boat. Set up for long range sailing they get good money here in Oz. When I crossed there was quite a number that I bumped into at different ports and they did fine also a couple of islander 36s. You will need to have a water maker {not big}, solar panels, a good auto pilot and maybe a back up, and definitely a tow generator. Its very doable and a blast. Oh I forgot lots of fuel cans.

Jd1 Ok, found it. This a a cut-and paste from http://www.unifliteworld.com/models/models.html

"The Famous (infamous) Blister Problem" The issue regarding the fire-retardant resins causing blisters in later years (1975+) was a result of a change in suppliers of the fire retardant resin (Hetron). Earlier models (prior to 1975) contained a fire retardant called "Hetron" manufactured by Dupont Chemical and these boats did not have any blistering problems. When Dupont ceased production of Hetron 1975, a different fire retardant was used from a different manufacturer. Unfortunately, the new fire retardant contained a solid form of the chemical bromine which, unfortunately, evolved into a gas when the fiberglass was warmed sufficiently. This happened to Uniflites in warmer climates like Florida and California more then it did in the Pacific Northwest. This bromine gas created an acid that ate its way out of the gel coat. For this reason, if you were to grind out a deep blister you would notice a "gooey" material. The only way to remove a blister properly is to grind it out, let it dry, then fill the hole with a vinylester resin ($$). It doesn't solve the problem entirely but should provide a strong barrier (plug) to prevent the blister from reaching the surface again. In reality, the blisters will likely return.

The Valiant blister issue is definitively not a 'standard' blister. I wish I knew where I read this (but I don't) .... it is not just a simple matter of the resin not setting. Apparently a gas forms (I seem to recall this formation is accelerated by temperature) which over time forms an acid and makes itself a nice little home. It applies to ALL the fiberglass and not just the hull or the under water area. As a result, you can peel as much as you want, whatever is left of the original fiberglass will continue doing it's thing.

Most of the techniques I'm aware of state you shouldn't remove the gel coat any more than is necessary. A thorough drying out followed by a good epoxy barrier coat on top of spot blister repairs should be more than enough - unless you have something more than simple blisters going on.

The depth of the blister into the laminate should tell you a lot about your situation. I've seen boats from reputable builders COVERED in blisters - like a terminal case of acne on a teenager - but none of then were deeper than the skin coat of mat - I've never seen a blister that went into the laminate proper.

My current boat is old enough to have never had a blister but my previous cored boat had a few - none were anything to worry about - not even deep enough to warrant fiber thickened filler.

I'd like to hear what CharliCobra has to say on this - he said he had a new peeling machine stolen from him, which certainly implies he intended to use it.
I'd say the same about most blisters out there...but Valiants are different. Because of resin never kicking, there can be large overlapping large blisters that are so bad, they are at the point where they are structural. So a peel job becomes a matter of saving the boat rather than just aesthetic.

rugosa Pretty boat from a far. BTW - brokers often refer to owning 2 boats as "the sickness"
