SF Bay - how long do you get out of Pettit Trinidad SR?

I'm wondering when I'll be hauling next - the bottom was done in Jan 2012 and seems to be in good condition right now. I had 2 coats of Pettit Trinidad SR put on.

Practical sailor did a longevity study that was published a couple months back. Most of the paints started loosing effectiveness after 2 years. I haul out and do mine every 3.

Thanks, I was pretty sure it would lose effectiveness after 2 years but not sure I could spin it out to 3.

Re: SF Bay - how long do you get out of Pettit Trinidad SR?

Hey Mark,

I think a lot depends on how often you clean your bottom, and how aggressively.

With two coats my bottom lasted around 30 months (South Bay)---I stretched it to 34, but the last couple of cleans were not that effective. Now it is repainted, I am initially using a hand towel to clean it - I'll move to something more abrasive later!

BTW, brace yourself for sticker shock when you do repaint - my recent job was way more expensive than my previous one. Like almost 50% more! Damn I wish my salary had gone up that much in 3 years.....

Re: SF Bay - how long do you get out of Pettit Trinidad SR?

Mark, we're in Grand Marina in Alameda. I've gotten anywhere from 2 to 5 years on a coat and a half. When I broke my leg skiing in 2009, most everything got delayed, as you can imagine. My quarterly diver still said the paint was good in year four, went to poor in year five. Other times it went to poor in 2 to 3 years.

If you have a diver, he'll tell you the condition.

Don't necessarily think it's always gotta be 2 years.

Forget what Practical Sailor or anyone else says, because what any paint does is pretty much "area" specific. Sausalito will be different than the Estuary. If you go up the Delta often, you'll get different performance. If you use your boat a lot, you'll get different performance.

Re: SF Bay - how long do you get out of Pettit Trinidad SR?

I had my bottom painted with one coat of that paint, in blue (I recall that this matters.) 34 months ago. I've never had the bottom cleaned. When I hauled last week, there was a thin coating of green-brown growth, but it didn't look that bad; I suspect with cleaning it would have had some more time on it, but I'm not sure about another whole summer. (It seems that summer is when everything starts to grow.)

So I'd say 2-3 summers is about right, based on my one data point. I have no idea how much variance there is in this.

I keep the boat in Redwood City.

One thing that's pretty interesting is that the blisters on the bottom weren't nearly as bad as they were the last time I hauled. They were actually only slightly noticeable, and it's possible that they even sort of "dried up" a little. The last time I hauled, I had just bought the boat, and the bottom was in really bad shape; it may have been in the water for ten years. There was so much stuff on the bottom. I'm not sure if this could have been related to the blisters in some way.

Re: SF Bay - how long do you get out of Pettit Trinidad SR?

We had our boat in Sausalito for 10 years. IIRC we used 2 coats of blue Petit Trinidad about every 2 years. Although we didn't race, speed was a concern as we used to make the long run outside to Duxburry every week during salmon season.

Around the beginning of the 2nd year we would start to get some growth around and just below the water line, which we could remove with a long handle brush. If you are in the South Bay the water may be warmer than in Sausalito?

Re: SF Bay - how long do you get out of Pettit Trinidad SR?

With two coats of Trinidad, three at the waterline and leading/trailing edges and gently cleaned every two months, I guarantee you will get 3+ years of good service. The product is not designed to be effective for significantly longer and claims to that effect should be viewed with skepticism.

Sounds good Matt, that is what I planned for.

OK, I'm curious. How do you apply a coat and a half?

I'm also curious about the reports of folks cleaning the bottom of their boats. I have never done that, harboring the belief that the paint is ablative and cleaning it shortens the life. Whenever I have sort of casually rubbed the paint I get a cloud of color in the water which strengthens the belief. Are the paints that get cleaned non-ablative? Or am I missing something more fundamental?
