FIBERGLASS AND HULL INFORMATION

P - 1 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-
est possible weight. The exact fiberglass laminate sched-
ule and construction techniques of each part is deter-
mined in accordance with the strength and rigidity re-
quired.
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. See Figure P1.

P - 2 FIBERGLASS CONSTRUCTION
The fiberglass components of Four Winns® boats are of
the finest quality materials, workmanship and construc-
tion techniques available. This ensures the structural in-
tegrity to provide years of boating enjoyment with mini-
mal 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.
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. Most Vista™ models utilize encapsu-
lated end-grain balsa core or coremat laminates to achieve
additional rigidity. Others utilize additional laminations of
woven roving to maintain strength and rigidity.
