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 Anodes (Zincs)

Do not paint between the zinc and the metal surface it contacts and do not paint over the zincs.
Your boat is equipped with sacrificial anodes to protect underwater metal parts from excessive deterioration. Check
sacrificial anodes regularly and replace if they have deteriorated more than 70%.
There are many factors that determine the rate at which sacrificial anodes deteriorate, including:
• Water temperature
• Salinity
• Water pollution
Stray current from the boat or dock may cause complete deterioration in just a few weeks. If there is rapid anode
deterioration, measure electrolytic corrosion around your boat with a Corrosion Test Meter. If sacrificial anodes are
not bonded correctly, they will not provide protection.
