BOTTOM PAINT
Factory installed antifouling paint is a top-of-the-line
product but does need periodic touching up. No paint can
be effective under all conditions of exposure. Man made
pollution and natural occurrences can adversely affect
antifouling paint performance. Extreme hot and cold
water temperatures, silt, dirt, oil, brackish water and even
electroylis can deminish the effects of antifouling paint.
Therefore, the vessel bottom needs to be checked
periodically to make sure it is clean and no growth is
occurring. Lightly scrub the bottom with a soft brush to
remove anything from the antifouling surface. Scrubbing
is particularly important with vessels that are idle for
extended periods of time.
The bottom coating is most effective when the boat is
being used on a continuous basis.
On select yachts maintain a 1 1/2" clearance from all
anodes, drive units and other underwater gear. Never paint
over anodes as they will cease to work properly.
Bottom paint needs to be periodically refurbished. Contact
your Regal yacht dealer or a marine professional for
additional information.
