I had Bamboo pulled today for a fresh coat of bottom paint. It's been 2 years and she looks pretty darn good! They'll wash her today, paint her tomorrow and be back in the water Thursday

If your boat has been in the water 2 years, you should give it at least 2 weeks on the hard to dry out some before you repaint.

That never happens around my marina. It's out, wash, and back in as quickly as they can make it happen.

When I had my bottom washed in March they told me I would be lucky if I make it through the season before needing a bottom job. I'm on my 4th year and the bottom was pretty clean other than the slime. Guess I'll be in your shoes shortly!

What paint are you using? Did you take anymore pictures of the bottom before and after washing?

I don't really see any reason for that; boats are pulled, painted, and splashed all the time.

Mine said 90 days dryout before they would do a barrier coat. getting it pulled week after next and getting a quote. Personally I think they give you a different story every depending on their mood, it is just a joke to them.

I went back over to the boat last night and didn't take pics but noticed only a few barnacles, and 2 years ago it was painted and splashed in 2 days as well so it seems to do a good job like that. I'm not sure what they're using but am going to ask this time, it'd be nice to know what's lasting so well.
Checked the Pintles or Gudgeons, they were solid and the rudder looks good. Going to wash and wax the hull today weather permitting.

There was no extra cost to me for the time on the hard; it was at a sailing club lot and that's what the guy doing the work told me. The boat had several blisters; maybe he was trying to drain them. It had been in the water for about 5 years. Took me over an hour with a pressure washer to clean most of the crud off of the hull when we pulled it out after I bought it.

That goes against everything I've ever heard/read. Plus, I've seen the little dimples that "weep" when a boat is hauled.

I'm getting a bottom job done at the end of the summer (when it starts to get REALLY hot down here). I haven't got any estimates yet, but know I'm going to have to let it dry out a bit.

However, re: the OP, I think there is a huge difference if you just need a pressure wash and a fresh coat of paint or if you need a complete strip, barrier coat and repaint from the ground up. In the first case, no extended drying out period is probably necessary.

Pulling and painting is one thing. Pulling and doing a barrier coat or fixing blisters is an entirely different matter. I don't agree with the statement that fiberglass is just a type of plastic. Perhaps the resin is but fiberglass is a amalgam of resin and glass cloth. And some of the resins used in the past facilitated water uptake. Hence osmotic blistering.
But like I said, fixing a blistered hull or one that needs to have a barrier coat is and probably should include a period of drying out. That's why you needed the barrier coat in the first place. But just pulling a stable hull and redoing the bottom paint over a stable surface should be able to be done pretty quickly.

Interesting article. I have a question and an observation. The question is, is there a rebuttal to that article that anyone has put out or, at least, an article that gives the opposite viewpoint? The observation is that what he suggests you do with blisters (sand them down and refill if necessary) seems to be exactly the same thing that other people who think "blisters are bad" recommend.

I also wonder what he, or you John, would recommend for my boat. My boat has not had a bottom job or paint in some years (not sure exactly how long). The bottom paint is almost entirely gone and there is some minor blistering. None are larger than a quarter, most smaller, and there's maybe half dozen or so of them. Maybe a few more. There are no soft spots whatsoever. What, if anything, do you think needs to be done to the hull before I have it repainted?

Matt, there are as many opinions as there are boats. I'd prep for painting and paint. I guess, since there are so few, you could drain the blisters and patch with new gelcoat since it would likely involve minimal effort and time. The only reason I'd do that is because, as van de Groot said, there's such a commmon perception that they're bad so, people might avoid buying the boat should you want to sell it someday. Of course, as he also said, if you fix them you can no longer use them as an excuse when you lose a race.

I've read a few articles (sorry, can't cite them) saying blisters are bad but I've discounted them for one reason or another. I think the usual reason was that they were written by or for people that had something to gain by scaring people about blisters.

You're right, Steve, the very early days of production with fiberglass yielded a larger problem with blisters although, I don't think its technically osmosis. As I understand it, the gelcoat was simply more porous so water got in behind it. That water hydrolyzed the surface gelcoat and became mildly acidic. But, everything I've read leads me to believe these to be cosmetic issues, not structural.

Remember, my opinion is worth precisely what you paid for it.

Whatever you do not puncture a blister and then smell it. When I had my pre-purchase survey done we found on small blister. The surveyor put a small hole in it and it started oozing. Not knowing any better I swiped a little of the liquid with my finger. Before the surveyor could stop me I smelled it. I'm telling you it nearly burned a hole in my lungs instantly! It was like taking a full whiff on the top of a lead acid battery!

When I was very young, my dad/uncle would took our 30' Owen's and beached it on a local island beach and set up a little camp/picnic for the day. Low tide comes, boat leans over, paint the half of the bottom that is exposed. Go back to sun and fun which included looking for clams and having a clam bake etc. Then rinse and repeat...i.e. Wait for tide to come in, and then float off... and then next week, same drill. Not sure others have utilized this technique, or if it would work for sailboat, but this thread reminded me of how "quickly" it was "pulled, painted, splashed".

Dennis, I've heard tales of beach painting but haven't seen it. A little update, went down and waxed the hull last night ([url="http://www.youtube.com/watch?v=5eW9fl6hgWU"]a little video[/url]). I dare say there's more shine than I've seen before!
Bottom paint pics. Oh and the paint was Trinidad 75 from Pettit. Going to keep her out one more day and replace the lower unit oil in the Tohatsu.

Dave, I wanted the dark blue bottom paint for our boat (same white hull and boot stripe) but WM didn't carry it. Yours looks so nice that I'm returning the medium blue to WM and I've ordered a gallon of the dark blue via the web!
Great color choice and thx for sharing the pix!

When I bought my used Catalina 250 from a boat dealer I had him put on a coat of RED ablative paint then a coat of BLACK. The dealer was adamant that BLACK was the only proper choice for longer lasting protection. I wanted the RED first coat to be sure I got two coats since it was being painted in another state. When I start seeing more RED than BLACK it will soon be time for a repaint.

I respectfully disagree. Drying out a vessel does prevent osmosis. Our previous owner was religious about it for 22 years as he circled twice. He would haul out here and there while he went home to visit or whatever. He reported developing osmosis issues when he stayed in for 2 years straight. They are disappointed in us for not hauling for more than two weeks. Living on the hard sucks!

Thanks guys, there's nothing like fresh bottom paint is there?! I think part of it is knowing that you're done for another year or two but it looks real good and the boat sails a little better!

I didn't have any blisters Gary. Didn't 2 years ago either. I have no idea why and I wonder what percentage of boats do get blisters and are they recurring?

Anyway, went and motored Bamboo the 2 miles back to her dock this morning. She was slipping through the water ever-so-nicely

I have this feeling I'll be out for a long sail this week-end. I'll bring the camera and video recorder
