We are having bottom of our boat (hunter 41DS ) stiipped and recoated with epoxy barrier coatings. We are considering going to water based antifouling paint. The boat is in NW washington and Canadian waters. I am wondering how the water based paint has worked for other boaters. Does it work as well micron 66 ? will it last a year or two?. or should I stick with the micron type bottom paint Thanks in advcance.

Hi sailor5017,
I've used Aquagraud in freshwater and have been very pleased with the product so far, easy to use and clean up is simple. This will be my third year and I'm only going to touch up a few areas before we splash the boat. Another benefit is a plastic can and you can store and reuse the product at a future time. Your results might vary in salt water. Good luck with the bottom job.

I have used micron 66 with no problems and has lasted 2+ years

I've used Pettit Hydrocoat (original formula with copper) and get satisfactory results in Western Long Island Sound (a very high fouling area). I have also used Micron 66 and it is much more effective, in salt water, but you cannot ever bring Micron 66 into fresh or brackish water or it will fail (deactivate and lose adhesion). I occasionally go up rivers, so Micron 66 is out of the question for me. The Hydrocoat is also much less expensive and is low VOC during application.

I can second what Knotallthere wrote. Aquaguard in fresh water performed well for me for three seasons. Going to recoat for this summer. Goes on like any other ablative and easy cleanup.

I've used HydroCoat on one boat and SeaHawk Monterey on my bigger boat. Both applied quickly and easily: cleaned up the same way. In the water both performed very well. After 4 months of immersion in the Atlantic, I had a bit of slime on the hull but that was it. Well, a bit of a patchy, green hula skirt at the waterline but that was adhered to gelcoat. Both are multi-year ablatives.
