The repair procedure for gel coat blisters is similar to
theproceduresoutlinedintheprevioussectiononcracks
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 mat-
ter, and loose paint. DO NOT sand deeply into
the gel coat, fiberglass cosmetic problems could
later result. After sanding, the surface should
bewipedwitharagtreatedwithacleanerrecom-
mended 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 accu-
mulated under the plastic, the hull is still “wet” and must
be allowed to dry longer before repairing.
Priortoapplicationoftheanti-foulingpaint,theboatowner
may consider coating the hull bottom with an epoxy coat-
ing. Four Winns recommends this procedure as a pre-
ventive and effective means of controlling osmotic blis-
tering. Most major anti-fouling paint manufacturers also
supply a line of epoxy undercoatings. Consult your Four
Winns dealer or local ship store for their recom-
mendations.
When the repair is completed, an application of an ep-
oxy 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 products.
M - 6 ANTI-FOULING PAINT
M - 7 HULL SUPPORT
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.
Proper support of the hull while it is out of the water is
imperative. Due to the design complexities, Four Winns
does not recommend trailers or storage cradles be
home-made. 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 wa-
ter. After a season’s use or sooner under certain condi-
tions, the anti-fouling paint may appear to be dissolving.
This is due to the paint’s chemical emission that in turn
retards marine growth. When this occurs, refinishing is
in order.
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 outdrives or
underwatergear. Seriousdamagetothesecom-
ponentscouldresult. DONOTplaceliftingstraps
on underwater gear. Be sure the strap is against
the hull surface only.
Four Winns recommends re-application 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 con-
ditions. See a Four Winns dealer for recommendations
on antifouling paint use in your area.
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 perfor-
mance deficiencies.
Four Winns trailers are available for all Vista models.
