Trinidad 75 Antifouling Review

In the last 3 years I've used 3 different kind of antifouling:

- Sea Hawk Island 44
- International
- Pettit Trinidad 75

I had great expectations for the Trinidad 75, the most expensive on the market.

It performed the worst. It is absolutely disappointing.

Since a picture is worth 1,000 words, judge for yourselves.

This is my keel after I left the boat for 4 weeks anchored in San Juan:

So 3 months later.

The OP could only answer that if he anchored his boat in the same harbor, in same time of year, with the other paints too.
Some city anchorages are well known for their insane fouling in short periods, like Cartegena, Colombia. 10 days there has hard hrowth on new paint. Not sure about San Juan.

Totally agree and the poor performance is also what we have been seeing in this product. It is also somewhat misleading that the Trinidad "75" doesn't actually contain 75% cuprous oxide as the front of the can suggests.
In fact, it's very difficult to get a factual amount of Cu2O in that paint current on Pettit page. On the Trini 75 the product data sheet it states, "Cuprous Oxide...up to 60.9%" .
The different color paints have different amounts listed in their specific safety data sheets for Cu2O: blue (1071 & 1074), 50-60%; red, 50-60%; black/special black, 60-70%; and light blue, 50-60%. Bottom line you need to read all the labeling info (includes online data sheets) to know what you are getting.
Even though we've been using Pettit Trinidad for a very long time, we have discussed switching to the Sea Hawk for our next bottom job. Hopefully, that did better.

So it could be that the paint you got was very old. I had a negative experience with SeaHawk Biocop. Fouled in a very short time. They did provide 2 gal of
new paint. But of course, I had to do the labor. From now on I am going to
check the lot codes and if they aren't the current year the paint will be returned

Re: Trinidad 75 Antifouling Review

We've had excellent results with Trinidad 75 SR - we are docked in the fertile soup of Apalachee Bay in North Florida. Usually get 3-4 years out of a bottom job. We have a monthly boat diver that mostly wipes the scum and scrapes the running gear. That said, we are always looking for something better.

Our powerboat has an ablative that we refresh annually.

We used Trinidada SR as our last bottom paint. No hard growth but slimed
in less than 6 weeks (Mid-Atlantic). Company reps said they were too busy
to come as it was a long drive. Never showed. You can make your own
conclusions about Pettit as a company. One of our largest chandleries dropped
Pettit and has added SeaHawk.

So they stopped carrying one of the best lines of anti fouling paint in order to do business with a pack of ex-convicts? Umm... OK

Re: Trinidad 75 Antifouling Review

A long time fan of Micron, I am not happy with its current composition. When they turned their dark red Micron to hot pink, I left the brand.

I am now looking forward to trying Pettit Odyssey Triton. The results displayed in their current advertising impress me.

I wonder why they have released Odyssey Triton in black and blue colors, but are taking much longer to release my color, red. Their marketing tells me that they are awaiting EPA approval for the red, green and white colors. I would like to know what the color difference has to do with EPA approval.

Re: Trinidad 75 Antifouling Review

Put on ABC 3 last October and just had to haul again after some #$%^% hit me in the marina whilst I was not on the boat.


Pretty happy with it so far as I have not cleaned the bottom in between and only been out on several short trips - Only slime to report.
