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 proceed.
NOTICE
During surface preparation, the hull should be
sanded only enough to remove any foreign
matter, and loose paint. DO NOT sand deeply
into the gel coat, fiberglass cosmetic problems
could later result. After sanding, the surface
should be wiped with a rag treated with a clean-
er recommended by the anti-fouling paint
manufacturer. The surface must be clean and
slightly rough to ensure paint adhesion.
To determine if the hull has dried sufficiently, tape one
square foot of household plastic wrap securely to the
hull bottom. Make sure all edges are sealed and let it
stand for twenty-four hours. If condensation has
accumulated under the plastic, the hull is still “wet”
and must be allowed to dry longer before repairing.
Prior to application of the anti-fouling paint, the boat
owner may consider coating the hull bottom with an
epoxy coating. Four Winns recommends this proce-

Four Winns recommends anti-fouling or bottom paint

periods of time. Anti-fouling paint reacts with water to

cradles be homemade. The boat is a valuable piece
of equipment. DO NOT risk permanent damage to
the hull structure in an attempt to save the cost of an
adequate support. Improper support can lead to
serious and permanent hull deformation.
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. For bottom paint line
location, refer to the Figure P2 at the end of this
section.
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.
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 anti-fouling paints used to
provide good marine growth protection 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
When attempting to raise the hull, never allow
one end of the boat to rise first, while letting
the opposite rest momentarily on the underwa-
ter gear. Serious damage to these components
could result. DO NOT place lifting straps on
underwater gear. Be sure the strap is against
the hull surface only and are in proper location
as indicated by the sling label location.
A trailer, or storage cradle designed for a larger or
smaller boat will not provide proper support for the
hull. This could lead to hull deformation and thus
serious performance deficien cies.
