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, hy-
drodynamics, structure, and strength of materials. 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 Vista™  models include  our patented
Stable-Vee™ hull design.    Pods on either side of the
outdrive extend the running surface beyond the transom.
These pods, plus the unique distribution of deadrise 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.
Always pre-drill fastening  holes with a  proper
size bit.  Pre-drilling will help prevent the fiber-
glassfromsplinteringandthuscausingunsightly
damage. 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, of which the 378 Vista™
is  one, 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.
