COATING THE BOAT BOTTOM
A clean hull improves boat performance.
The boat bottom should be kept as clean
of marine growths as possible. If neces-
sary, the boat bottom can be coated with
an anti-fouling paint approved for your
area to inhibit marine growth.
Do not use anti-fouling paint which
includes copper or graphite. These paints
can cause more rapid engine corrosion.
