Default Pettit Trinidad or Interlux CSC

I am looking at getting my boat bottom painted, got a good quote from a guy in charleton, he will do the job for $25/ft. including barrier coat, and my choice either Tinidad or CSC. The boat will be in fresh water, only real enemy is slime & algae, and will be trailered ocationally for trips to the coast or to the fuel station if gas prices dictate that this would be benifitial. What would be the advantage of either one, and which is the most durable over time?

Choose the paint that is most appropriate for a powerboat. I used Petit Trinidad for my sailboat years ago because it had the highest cuprous oxide content(to fight algea, slime, and barnacles). However, it was a soft ablative paint that is ideal for sailboats. It worked very well given the fact that I was living on the West Coast of FL at the time.



Specifically, I would check around to find out what is best for powerboats: harder paint and the fact that you will be trailering it. It is quite possible that Pettit has come out with a paint for your needs, I just do not know. Also, I highly recommend Interlux barrier coat protection products. This was used on my sailboat as well with very good results.

Definately go with the Petit. Much better product than Interlux.

I had used both in the pass and the interlux didn't hold up as good after one season.My boat stayed in fresh water till it was ran out to saltwater,Petit held up.$25 a foot,stripping old paint and bottom barrier,then paint?You better ask how many coats of each.

The two paints will perform differently.

Micron CSC is a self polishing copolymer antifouling. It will wear away with use, eliminating build up of old spent coatings. This also means that the longevity of Micron Extra with Biolux is related to the number of coats applied. Basically, you powerwash and check the paint wear once a year, and touch up any areas that have worn through. CSC is not suitable for trailered boats or out of water storage, but it is probably OK for trailering out of water for a short time.

Trinidad is a multi-season hard bottom paint. The antifoulant is cuprous oxide and it is embedded in epoxy paint. Over time, the cuprous oxide leaches out, providing the antifouling. After two or three years, all of the cuprous oxde is used up, and what's left on the hull is just the epoxy carrier. Then you can add more coats of new paint. Eventually, you will have enough build-up on there that you have to sand it all off and start the process over. Hard bottom paint is very effective, and is considered the "classic" antifoulant. Hard bottom paint will lose its effectiveness if it is stored out of water for prolonged periods like winter storage. Its main disadvantage is when you get to the point where it all has to come off.


Becasuse your main problem is slime and algae, I would choose a slightly different paint than the choices you have. Trinidad SR is Trinidad, but with a biocide added to attack the slime problem. Micron Extra is the same as CSC, but with a biocide added.

If you plan to trailer frequently and want the flexibility to dry store the boat , I would choose Trinidad Vivid. It has most of the advantages of Trinidad, but does not build up as much. It has both antifoulant and biocide in it. It is available in a wider choice of colors than the others.

VC Offshore's held up fine on my boat - 40kts, flat-bottom in brackish and murky fresh water.

No experience with CSC - my apologies. Just wanted to hold a hand up for interlux as their product's worked very well for us. We're into our 2nd year with it now. We're wet-slipped 365 days / yr save maintenance hauls.

the paint job will be new paint, on a previously unpainted hull.

It sounds like itwonder has it all figured out! Thanks for enlightening me, it has been a while since I had to deal with bottom paints!

I use Micron CSC and although I do paint each year, it is a multi season paint, the same as practically all ablative paints. I was told my a rep. at the Miami Boat Show, that CSC would be better for my needs than the Extra, in that Extra would wash off faster than CSC on a fast hull. Evidently the Extra may be a little softer?? A neighbor used the Extra on a fast hull, and both the CSC and Extra held up equally well. Both can be left out of the water for extended periods of time. I would suggest pressure washing prior to launching after extended dry storage.
