Special Care For Moored Boats

• To help seal the hull bottom and reduce the possibility of gelcoat blistering on moored boats,
apply an epoxy barrier coating. The barrier coating should be covered with several coats of
anti-fouling paint.
• Many states regulate the chemical content of bottom paints in order to meet environmental
standards. Check with your local dealer about recommended bottom paints, and about the
laws in effect in your area.
• Whether moored in saltwater or freshwater, your boat will collect marine growth on its hull bottom.
• This will detract from the boat's beauty, greatly affect its performance and may damage the gelcoat.
• There are two methods of slowing marine growth:
1. Periodically haul the boat out of the water and scrub the hull bottom with a bristle brush and a solution of soap
and water.
2. Occasionally re-paint the hull below the waterline with a good grade of anti-fouling paint.

Sacrificial Anode (Zinc)

• Do NOT paint between the zinc and the metal surface it contacts and do NOT paint over
the zinc.
• If the zinc is NOT bonded correctly, it will NOT provide protection.
Your boat is equipped with a sacrificial anode (zinc) to pro-
tect underwater metal parts from excessive deterioration.
Check the zinc regularly and replace it if it has deteriorated
more than 70%.
Many factors affect the rate at which the zinc deteriorates,
including:
• Water temperature
• Salinity
• Water pollution
• Stray Electrical current
Stray electrical current from your boat, another boat, or the
dock may cause complete deterioration of the zinc in just a
few weeks. If there is rapid zinc deterioration, measure the
electrolytic corrosion around your boat with a corrosion
test meter.
