We have two boat friends in the southern Carib with Trinidad SR and both are having premature growth issues. Perhaps there was a bad batch, or a reformulation, or maybe it isn't the best paint for the Carib?

As for the gold standard, in the Carib it is Seahawk Island 44. I won't be drawn into a debate on that.

Seahawk Island 44 is a tin based paint and illegal in the USA.

In anticipation of copper reduction legislation, Trinidad has been reformulated from 70+% down to 60% in California. Is this the case in other areas? I don't know. I do know that so far, here in the Bay Area, I can't tell the difference between the two.

If you don't like useing seahawk 44, just stay in US waters and don't go places that use it for your bottom paint !! But saying thats it's illegal don't help much LOL If ya cruise for a while in the southern waters of the world and need bottom paint what ya gonna do keep a few cans of the leglal stuff aboard or use what the other folks use where you are at !! Justa thought from folks who sometimes don't see the USA for for 3 or 4 yrs at atime !! I use the nastyest stuff I can find when Im out of the country as it just works better and longer

!! just a thought

How do you feel about cutting fins off of sharks for soup? (Just wondered)

I had a friend who was fond of stating, "Rape mother nature while you have the chance."

There is a reason why Tin is outlawed in many places. As for us, we wouldn't buy Trinidad OR Seahawk 44, even if it was legal, just because of the price.

We've bought bottom paint in about 20 countries, whatever the local use and is cheap. IT'S ALL WORKED ABOUT THE SAME. (of course no-one who'se paid $400/gallon is going to admit it's anything but special).

After painting our bottom we expect it to go 6 months with hardly any growth, but sometimes it's less. (Cartagena, Columbia it was two weeks!).
At six months we clean it or have it cleaned. At nine months we're cleaning it about every six weeks. After a year we'll re-do the bottom, more for speed than necessity. This year we intend to skip a year and have it cleaned every month because the local (Mexican) paint we used is holding up really well. (it costs $152/gal)

I meant $400 for a 40-ft boat, which is about a gallon plus a quart. Not sure about your math skills, but if I'm hauling every 3 (at the very minimum) to 4 years compared to every year or two under your scenario, then cost of paint works out to be the same while you'll end up paying for an extra haul out along with additional labor.

Pettit Trinidad SR contains up to 65% cuprous oxide (copper content) for the non-Irgarol formula, and up to 60% cuprous oxide for the formula containing 2% Irgarol—plus slime-fighting biocides.

It does NOT contain tributyl tin (TBT), and is NOT banned or restricted anywhere (I know of).

Under the spell of the greenies, Washington State pols are doing their best to ban all copper paint.

Something doesn't make sense. You had a quick bottom cleaning a month ago. What does quick mean? One that was so quick they didn't bother removing the barnacles? I'd be very surprised if barnacles grew in a month on Trinidad SR (or on anything) so that means they weren't removed at the clean.

I've personally had two years and 9 months out of this paint, could have got 3, and the only thing is that in the last year the rate of bottom cleaning needed goes up.

There's nothing wrong with the paint.

Have you looked at where the flaking is? In my case, the top 2 layers of Trinidad were very well adhered but the problem was 20 layers deeper, at the gelcoat, where there was loss of adhesion.

Cheechako · 19-03-2012, 18:02

Frankly, I never met anyone who was satisfied with their paint in the carribean.... unless they had done it in the country of Trinidad and were headed north. It didnt really matter what paint it was. Barnacles grow... a LOT. This was 10 years ago too. The only ones that seemed to do better were those who moved on constantly. When you sit , they grow. It may kill them eventually, but they are already large lumps fastened to the hull at that point.

OTOH- Jotun paint put on in Trinidad lasted 3-4 months returning to Florida. Sat 1.5 years in a back canal with growth all over the sea wall and pilings while the boat was for sale. When I visited my boat I had a diver down.. after a couple of minutes he came up and told me it was a waste of time... there was nothing on the boat!
Us makers should just concentrate on making paint that cleans easy (maybe that old teflon bottom paint WAS a good idea!) as their hands are tied when it comes to making bottom paint that actually works....

That's the whole point behind hard anti-foulings like Trinidad SR - they have anti-fouling properties AND clean easily.

Cavalier MK2 · 20-03-2012, 08:36

This is a tough debate, hopefully not won when life in the oceans ceases to exist....A easy to scrub paint makes up for many adhesions. ....Perhaps in this day of biotechnology and cloning we will start to see living cultures for paint alternatives. "Say nice shark skin, does it come striped? " Or how about salmon slime barnacle repellent? Of course if your boat grows fins it might be cheating during a light air race........

We can debate application issues, etc but at the end of the day we are online and you cant see what I did, have done for a living etc. I'm reporting facts on a forum for reviewing products.

I have a hard time believing that this is the best product out there, and eagerly look forward to hearing from others in warm climes who have had better luck with paints, and I am disappointed I hadn't found a better product prior to applying. At the current growth rate I would have been far better off not painting, or painting with the cheapest paint I could have found.

If you plan to stay in the Carib and not go to the US, then Seahawk Island 44 or Blue Water Marine Caribbean Gold will work better than any other paint.
