We keep our boat in the Chesapeake; some salt water, some brackish water, & even some freshwater areas. In 2013, I applied Pettit's Hydrocoat, a water based AF paint. No paint was applied at the beginning of the 2014 season. Boat was hauled last week; some slime & mud, but no hard growth. Pettit advertises it as a multi-season paint; my conversation w/tech folks led me to think at least 2 seasons, perhaps more, might be possible. So far, I like it.

I was ready to go with the Pettit Trinidad SR after fstbttms recommendation and my further research it appeared to be the better of the 2 paints for the performance I wanted. Then I talked with both companies tech support, after explaining where the boat is and what improvement I was looking for over what has been used neither one claimed their paint was better than the other. They both said that their paints were very similar in performance, the Interlux tech pointed out that because it was getting the interprotect 2000 barrier coat that if any problems arose during the warranty period there would be no question that it would be covered. If it had the Trinidad then there's the possibility that Interlux and Pettit would point fingers back and forth at who's product is at fault. He also told me that Ultra has less cooper it is more efficient in how it is released and having less copper is why it's cheaper than Trinidad. This is the point that I started to re-think my decision to go with Trinidad, the warranty info was the deciding factor. Talked with the marina yesterday and decided to go with Ultra, a red base coat and then a black 2nd coat and a 3rd coat in high wear areas, now just waiting for warm weather.

FYI- I find that there is marked and very noticeable difference in performance between Ultra and Trinidad. YMMV.

River Cruiser...You are wise to keep the barrier and top coats of the same mfg. I stripped my bottom and replaced the barrier and top coats last spring. Not a cheap project. Both supplied by the same company. Well guess what we found in the fall when we hauled the boat. Major top coat failure. Needless to say there was no fingers being pointed. Just a simple statement. We'll stand behind our product. It's being taken care of, no further questions.

While you are the professional and I am just a consumer....I get a SOLID 5 years out of Ultra Bio!!! If there is a "marked and very noticeable difference in performance" in the Trinidad, I'd be curious to see what I would get!!!!....10 years????? Sorry brutha, I am absolutely sold on Ultra!!!! 5 years is hard to beat. I am almost two years into the current paint. I don't expect to paint it for at least another two years.....

We use Trinidad Petit SR 60 last 3-4 years and that is in warm salt water of South Georgia and Florida. Lasted 6 years on our sailboat but we were very gentle with the monthly bottom cleaning. See @ TheOffice: @ TheOffice: Bottom's Up or at least painted All done!

I have never seen any paint provide good anti fouling performance for anything approaching 5 years. But that's here and you're there. Again, I guess YMMV.

I agree that the first time over an epoxy barrier coat that you stay in manufacturer...just for "bonding" till the product is fully cured.

After the first year...you can always top off with whatever is quoted as compatable.

My personal experience has shown bottom paint results to wildly vary depending on water conditions, boat use and paint application.

Hard to beat soft paint full of copper for slow boats that don't move much....beyond that it can vary a lot.

While I prefer ablatives and Interlude after a bad experience with Petit... Trinidad seems to have the best rep of any paint I know....but only for the boats that can really use it.

Sea Hawk paint was the last bottom job that impressed me on a boat that sat a lot. Forget which particular mix though.

I think the fouling problem where I'am at on the mississippi can be blamed on agricultural runoff, plenty of nutrients in the warm water and very calm conditions in the harbor.

I'm through w high performance bottom paints. Put on Interlux Micron Extra and it lasted for 3 years. Great but ... they claimed it as an "ablative" coating and it definitely wasn't. Had to scrape it all off and I'm NOT inclined to do that again. I use a very inexpensive bottom coat now called "Sea Mate" by Petitt. Less than $100 a gallon. Ninety five percent of the boats near the place where we lived in SE Alaska used this coating .... and just put more on every year or so.

Had just the opposite experience...Petitt that didn't ablate....thus my pist about almost anything applied good may work..or not......roll the dice...

Have always had good experience with fiberglass bottomkote, hard paint. red actually works best in some areas, but black has always performed well. We used red on the bottom and black on visible portions one year. Now has an additive for soft growth which is the biggest problem in the lakes. Some folks add red pepper to deter zebra mussels, but may be a urban legend.
