14.5 BOTTOM MAINTENANCE
14.5.1 Bottom Antifouling Coating
Your yacht’s hull bottom was coated with two coats of a high-quality
antifouling paint that must be maintained to prevent the formation of
marine growth. Uncontrolled marine growth (barnacles, slime, grasses)
on the bottom of the yacht and on the propellers and other running gear
causes a remarkable reduction in operating efficiency and with time can
damage the gel-coat.
Selecting the proper antifouling paint for your yacht is important to
maintaining a clean bottom in the waters in which you operate the yacht.
There are many antifouling products available, each designed for specific
uses. Knowing the performance characteristics of each paint is key to
making the right choice of the coating that will best protect your yacht’s
bottom in your area of operation. If you need assistance to select the right
coating for Your yacht, contact the BERTRAM Customer Support.
14.5.2 Bottom inspection
Periodic bottom cleaning and inspections should be performed on a
regular schedule when the yacht is in a dry shore. The effectiveness of
the antifouling paint primarily depends on local conditions in the waters
where the yacht operates.
Marine growth building up on the hull can be removed with the help of a
qualified and experienced diver.
A diver can remove marine growth from the hull bottom, rudders,
propellers, shafts and trim tabs with a scraper, sponges and/or
brushes.
At the same time, the diver can check the paint, the equipment and
fittings. He can determine if the antifouling paint is still effective. If a fresh
application is needed to retard marine growth, it will be necessary to
arrange for the yacht to be dry-shored.
