Max I've seen is 5-6 months. It has to be cleaned bi-weekly in the winter and weekly in the summer here in Southwest Florida. This product is useless. It's worse than not having bottom paint.
It could last multiple years depending on the maintenance. You you clean it once or twice a month or run the boat often you should be good. As for dry time we’ve tested the boat the next day after applying. Visit nascoworldwide.com for pricing. It’s based off of hull length.
This product is absolute junk if you keep your boat in the water. No antifouling, turns yellow in a week and looks horrible, you need to hire a diver every week to scrub it and it still looks like crap. Triple the price of bottom paint.
Put it on my 37 ft Axopar and after 6 months the bottom is a disaster. Clearly Center Console Only can not be trusted. Hullmaxx takes 3x the labor and 2-3x the cost and is absolutely NOT worth it. This is a real life review not this fake video.
