The problem
The underwater hull was heavily fouled, with barnacles and marine growth across the bottom, the propellers and the thruster tunnels. Growth like this slows a yacht down and raises its fuel use.
What we did
We hauled the yacht out, pressure-washed the hull and running gear, and cleaned the barnacles off the propellers and thrusters. We then applied two coats of primer and two coats of antifouling, each by hand, with the full cure time between coats.
The result
The yacht went back in the water with a clean, smooth hull and fresh black antifouling from the waterline down. In Gulf water, four hand-applied coats give roughly another season before the next haul-out.
