Wayne, I have used Hydrocoat on my Ocean Alexander trawler in Lake Michigan for the last 4 years. Love the stuff. Easy to apply, easy clean up and no noxious smell. Power wash the bottom at the end of the season all good. The only bottom is at trawler speeds the paint doesn't seem to wear away like an ablative paint should so some paint build up occurs.
