FIBERGLASS AND HULL INFORMATION
Fiberglass cockpit liners and seat base are constructed
similar to the hull. Balsa core or coremat laminations
are utilized when necessary.

HULL DESIGN INFORMATION
Four Winns® boats are designed using the sound engi-
neering and mathematical principles of hydrostatics,
hydrodynamics,structure,andstrengthofmaterials. The
materials utilized provide optimum strength at the light-
estpossibleweight. Theexactfiberglasslaminatesched-
ule and construction techniques of each part is deter-
mined in accordance with the strength and rigidity re-
quired.
In addition to a thorough visual inspection of each fiber-
glass component, samples are measured using special
equipment, for fiberglass reinforcement to resin ratio,
laminate configuration, weight and thickness. By these
procedures Four Winns ensures proper composition.

EQUIPMENT INSTALLATION
All Four Winns Sundowner™ models include our pat-
ented Stable-Vee® hull design. Pods on either side of
the outdrive extend the running surface beyond the tran-
som. These pods, plus the unique distribution of dead-
rise from transom to bow, allows Four Winns to place
more hull in the water than deep-vee designs of similar
length and beam. This results in better boat handling
whether on plane, during turns, or at rest.
Many boats are used for specific purposes or under con-
ditions which require the addition of special equipment
to the hull or deck. Special care must be taken during
the installation of any equipment 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 compound should be
used elsewhere.

FIBERGLASS CONSTRUCTION
NOTICE
DO NOT install any item onto or through the
hull without adequately sealing the hull area
penetrated by the installed item or related fas-
teners. Improper installations could cause leak-
age or allow water absorption and thus cause
serious hull damage.
The fiberglass components of Four Winns® boats are
of the finest quality materials, workmanship and con-
struction techniques available. This ensures the struc-
tural integrity to provide years of boating enjoyment with
minimal maintenance.
The construction of a Four Winns® hull begins with the
application of gel coat to the mold. The gel coat is ap-
proximately 25 mils thick. A coat of resin and chopped
fiberglass is then sprayed into the hull and carefully hand
rolled until it is securely affixed to the gel coat.

bit. Predrilling will help prevent the fiberglass
fromsplinteringandthuscausingunsightlydam-
age. Also, countersink holes to prevent the gel
coat from chipping.
A number of fiberglass layers and woven roving are ap-
plied 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 addi-
tional 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.
Any equipment which will be subjected to cyclic loading
or significant force should be through-bolted to a fiber-
glass component. A butt block or backing plate should
be used to strengthen any area onto which an item will
be mounted.
The hull support stringers are located using special tools,
and are fiberglassed into place. This ensures a strong,
rigid hull, permanently formed into a solid assembly, free
of distortions.
