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 construction of a Four Winns hull begins with the
application of gel coat to the mold. The gel coat is ap-
proximately 20 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, counter sink 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 Any equipment which will be subjected to cyclic loading
