Anti-Fouling Paint; Hull Support - Four winns V Series Owner's Manual

The repair procedure for gel coat blisters is similar to
the procedures outlined in the previous section on
cracks and gouges. There is an exception however, in
that the hull must dry out for several days or possibly
weeks before repairs can pro ceed.
To determine if the hull has dried sufficiently, tape one
square foot of household plastic wrap secure ly to the
hull bottom. Make sure all edges are sealed and let it
stand for twenty-four hours. If condensa tion has
accumulated under the plastic, the hull is still "wet"
and must be allowed to dry longer before repairing.
When the repair is completed, an application of an
epoxy barrier coat should be considered. This will help
prevent the possibility of reoccurrence of blisters. Your
Four Winns dealer or local ship store will have informa-
tion on barrier coat prod ucts.

ANTI-FOULING PAINT

Four Winns recommends anti-fouling or bottom paint
for boats which will be kept in the water for extended
periods of time. Anti-fouling paint reacts with water to
retard the growth of algae, barnacles and other marine
growth on the hull. In addition to marine growth, it
offers protection against excessive water pollution.
NOTICE
Most countries have introduced legislation
controlling the use of anti-fouling agents. Always
abide by these regulations.
Anti-fouling paint begins reaction upon contact with
water. After a season's use or sooner under certain
conditions, the anti-fouling paint may appear to be
dissolving. This is due to the paint's chemical emis-
sion that in turn retards marine growth. When this
occurs, refinishing is in order. Consult your engine
operator's manual for their recommendations regard-
ing drive-unit and anti-fouling paint.
Four Winns recommends reapplication of the anti-
fouling paint seasonally. The effectiveness of the paint
will be drastically reduced if used longer. Though
Four Winns has found the use of anti-fouling paints
provide good marine growth protec tion in most water,
other paints may be more effective in certain water
conditions. See a Four Winns dealer for recommenda-
tions on anti-fouling paint use in your area.

NOTICE
During surface preparation, the hull should be
sanded only enough to remove any for eign

Prior to application of the anti-fouling paint, the boat
owner may consider coat ing the hull bottom with an
epoxy coating. Four Winns recommends this proce-
dure as a preventive and effective means of control-
ling osmotic blistering. Most major anti-fouling paint
manufacturers also supply a line of epoxy undercoat-
ings. Consult your Four Winns dealer for recom-
mendations on epoxy undercoatings.

HULL SUPPORT

Proper support of the hull while it is out of the water is
imperative. Due to the design complexi ties, Four Winns
does not recommend storage cradles be homemade.
The boat is a valuable piece of equipment. DO NOT risk
per ma nent damage to the hull structure in an at tempt to
save the cost of an adequate support. Improp er support
can lead to serious and perma nent hull deformation.
While lifting the boat, ensure slings are in the
proper locations as indicated by the sling
location labels. Failure to do so may result in
permanent hull structure damage and will
invalidate the hull structure warranty.
NOTICE
When at tem pting to raise the hull, nev er allow
one end of the boat to rise first, while let ting the
op po site rest mo men tarily on the drive(s) or
un der wa ter gear. Seri ous dam age to these
com po n ents could result. DO NOT place lifting
straps on drive(s) or underwa ter gear. Be sure
the strap is against the hull surface only and
are in proper location as indicated by the sling
label location.
