Many boats are used for specific purposes or under
conditions which require the addition of special equip-
ment to the hull or deck. Special care must be taken
during the installation of any equi pment to a fiberglass
com ponent. A polysulfide or butyl based sealant
should be used to seal installations below the water
line. Silicone “marine” seal or similar bedding com-
pound should be used elsewhere.
gineering and mathematical principles of hydrostatics,
hydrodynamics, structure, and strength of materials.
The materials utilized provide optimum strength at the
lightest possible weight. The exact fiberglass laminate
schedule and construction techniques of each part
is determined in accordance with the strength and
rigidity required.
NOTICE
P - 2 FIBERGLASS CONSTRUCTION
DO NOT install any item onto or through the
hull without adequately sealing the hull area
penetrated by the installed item or related
fasteners. Improper installations could cause
leakage or allow water absorption and thus
cause serious hull damage.
The fiberglass components of Four Winns boats
®
are of the finest quality materials, work manship and
construction techniques available. This ensures the
structural integrity to provide years of boating enjoy-
ment with minimal maintenance.
Always predrill fastening holes with a proper
size bit. Predrilling will help prevent the
fiberglass from splintering and thus causing
unsightly damage. Also, countersink holes to
prevent the gel coat from chipping.
The construction of a Four Winns hull begins with
®
the application of gel coat to the mold. The gel coat
is approximately 25 mils thick. A coat of resin and
chopped fiberglass is then sprayed into the hull and
carefully hand rolled until it is se curely affixed to the
gel coat.
Any equipment which will be subjected to cyclic load-
ing or significant force should be through-bolted to a
fiberglass compo nent. A butt block or backing plate
should be used to strengthen any area onto which an
item will be mounted.
A number of fiberglass layers and woven roving are
applied to the above laminate. Each layer is hand-laid
and hand-rolled. The keel and chine areas have
fiberglass woven roving overlapped in these areas
to provide additional strength. Some models utilize
encapsulated end-grain balsa core or coremat
laminates to achieve additional rigidity. Others utilize
additional laminations of woven roving to maintain
strength and rigidity.
P - 4 FIBERGLASS CARE & MAINTENANCE
Fiberglass is affected by weathering processes and
requires maintenance on a periodic basis to help
maintain the beauty and shine. The effects upon the
gel coat will be dependent upon boating conditions,
storage, type of use, and the care given to the boat
during the boating season.
The hull support stringers are located using special
tools, and are fiberglassed/bonded into place. This
ensures a strong, rigid hull, permanently formed into
a solid assembly, free of distortions.
Four Winns utilizes fade-fighting gel coat in the exte-

rior finish. It is specially formulat ed to resist fading and
yellowing, and retain more of its original gloss than
lesser grade gel coats. However, it is still important to
maintain the gel coat to protect the finish.
In addition to a thorough visual inspection of each
fiberglass component, samples are mea sured us-
ing special equipment, for fiberglass reinforce ment
to resin ratio, laminate configura tion, weight and
thickness. By these procedures Four Winns ensures
proper composition.
A. General Maintenance
For freshwater use, the boat should be washed
once or twice a month. When using in a salt water
environment, considerably more care will be neces-
sary. Be careful when selecting a cleaning agent.
Hand dishwashing detergents are usually gentle
and are recommended for cleaning gel coat. Cleaning
