Specifications & Features Hull • NPG Isothalic gelcoat for superior gloss retention • Infused epoxy hull laminate producing a strength to weight ratio not attainable in any production polyester laminates • Epoxy’s superior adhesive strength reduces overall hull weight while increasing strength producing a faster and safer performance cruising yacht • Strict resin control through infusion produces glass to resin ratio of 65% glass, 35% resin. (production polyester boats are typically 25% glass, 75% resin=heavy and brittle) • Superior fatigue and cyclic loading characteristics of epoxy ensure a hull that retains its shape and strength longer resulting in higher resale value • Extensive internal structure designed to carry rig and keel loads, glass taped into hull using modified epoxy resin • Hull is vacuum-bagged and structure is infused in “one shot” thus does not rely on secondary bonding of structural materials • Epoxy hull laminate is far stronger than any polyester laminate of similar weight, i.e. greater safety margins while delivering superior performance over normal production polyester hulls • 90 degree throw, Marelon, flush thru hull fittings. Marelon fittings are UL and ABS approved and are corrosion free • Complete interior paintout for enhanced cosmetics and to seal interior laminate surfaces • Built to meet ABS Plan Certification • Industry leading, non-prorated 15 year hull structural and blister guarantee • Warranty is transferable • Synthetic foam hull coring, provides lightweight structure, stiffness, sound and thermal insulation and superior impact resistance Deck • Deck is a balanced composite laminate Phenol B epoxy resin, uni-directional “E”-glass reinforcement, and high strength/stiffness sealed end grain balsa coring • Our custom resin infusion process creates the best resin-toglass reinforcement ratio possible resulting in the stiffest, lightest, strongest deck in production boatbuilding • Weight saved high increases righting moment improving safety and performance • Infusion process with epoxy resin provides a stronger more fatigue resistant deck laminate than typical production polyester deck laminates • The deck is locally reinforced at high load areas with additional plies of bi-directional “E”-glass reinforcement • NPG Isothalic gelcoat for improved color and gloss retention • Gelcoat is formulated for greater flexibility reducing occurrence of common gel coat crazing • White or off-white gelcoat with patterned, molded non-skid surface on horizontal deck areas. • Balsa coring also offers acoustic as well as thermal insulation increasing interior comfort • Core “windows” at all deck hardware installations. Window is reinforced with solid laminate and isolates hardware installations from cored laminate, reducing stress crazes around hardware often seen in laminates reinforced with plywood and eliminates rot problems associated with decks reinforced with plywood • Structurally loaded hardware backed with either FRP or 6061 T6 aluminum backing plates • Time-tested hull to deck joint. Deck is fastened to inward facing hull flange with integrally molded hardened 6061 T6 aluminum bar forming a full sheer length backing plate • Stainless steel fasteners sized to meet or exceed ABS standard for offshore use, are drilled and tapped into aluminum bar, offering full serviceability from the outside of the boat • Deck to hull joint bonded with 3M 5200 adhesive sealant Keel & Ballast • 6,000 lb. (2722 kg) fin, 6,200 lb. (2812 kg) beavertail or 6,400 lb. (2903 kg.) keel centerboard, 4% antimonial hardened lead casting • Template ground for fit and maximum performance • Faired and epoxy coated • Deep fin, beavertail bulb design, or keel/centerboard significantly lowers center of gravity improving righting moment. Result is increased sail carrying ability, performance and safety • Ballast is thru-bolted to hull with cast in place stainless steel bolts. Quantity and size exceed ABS standard for offshore use Rudder & Steering System • Pedestal style rack and pinion steering pedestal • 44” stainless steel Commodore wheel with leather cover • Stainless steel pedestal guard • Single-lever, pedestal-mounted engine control with stainless steel handle • 5” binnacle compass • High density, closed cell urethane foam rudder blade with modified epoxy reinforced skins • 3 1/2” type 304 stainless steel rudder post • High density low friction rudder bearings • Bronze rudder stuffing box • Emergency tiller
