Hull Preparation
The hull on planing boats starts with a V to cut through the waves. Then it flares out in the stern to a flatter concept. This allows the boat to get up on top of the water to go faster depending on the horsepower aboard. The hull design and horsepower contribute to the builder’s designed speed—at perfect conditions right from the factory. Now consider the condition of the hull itself.
Dirt and slime create more resistance to that slippery water your boat is running through. The most pristine waters can foster marine growth. Barnacles are obvious, but what about algae or seaweed? Choose an anti-fouling paint that works well for the waters you call home port and lasts longer than the lower price alternative.
Barrier Coat and Anti-fouling Paint
When hauling the boat for seasonal bottom job cleaning, check the existing paint for wear and adhesion. Is it smooth or has the bottom of the boat been painted too many times without taking the old paint off entirely? If the paint shows too many moon craters or high and low spots, then the bottom may have to be blasted to remove everything down to the original gel coat.
Now that your hull has been properly prepped, it’s time to apply a barrier coating and, finally, good anti-fouling paint. The decision of what type of paint to use is dependent on the local waters in which you plan to boat and the kind of sea creatures that grow in your area. Ask other boaters what anti-fouling paint they favor. Check with your local yard experts too.
