Speciï¬�cations & Features Hull • Hull construction is a vacuum-bagged, wet-preg epoxy, unidirectional “E” glass, and CoreCell core laminate locally reinforced with carbon ï¬�ber. The hull is postcured to 145 degrees • The incredible adhesion properties of epoxy eliminates all chopped strand mat from the structural hull laminate schedule. Chopped strand mat is the cheapest, heaviest, and weakest component that dominates conventional polyester hull construction • The vacuum-bagging process and strict resin control through use of resin impregnators produces a hull laminate with 65% glass reinforcement content. The industry norm for polyester resin hull laminates is 25% glass content, this produces a stronger yet lighter hull • CoreCell closed cell linear polymer foam coring is used for maximum impact resistance, stiffness, strength, and light weight. The cored hull also offers superior hull insulating properties, both thermal and acoustical • Pound-for-pound a post-cured epoxy resin laminate is far stronger than any polyester resin laminate • The laminate in the keel area is reinforced with multiple plies of high-tensile carbon-ï¬�ber unidirectional reinforcements • The oven post-curing process maximizes the physical properties of the laminate and minimizes future post-cure cosmetic blemishes characteristically seen in conventional polyester laminates • Premium grade gelcoat provides superior gloss, fade resistance, and resistance to surface crazing • Hull cosmetics are also enhanced by the extremely low shrinkage of epoxy resin vs. polyester resin (1% vs 7%) and the reduction in overall resin content thus eliminating or reducing post-cure hull distortions found in conventional polyester laminates • Interior is completely painted out for enhanced cosmetics and to seal interior laminate surfaces • Hull is backed by industry-leading, non-prorated, transferable 15-year no blister, hull structure warranty Deck • Deck is a balanced composite laminate utilizing vinylester resin, uni-directional “E”-glass reinforcement, and high strength/stiffness Baltek premium AL 600 balsa coring • Our custom resin infusion process creates the best resin to glass reinforcement ratio possible resulting in the stiffest, lightest, strongest deck in production boatbuilding • Deck is locally reinforced at high load areas with additional plies of bi-directional “E”-glass reinforcement • White, light gray, or white/sandstone and white/gray two-tone decks with patterned non-skid are available • Premium grade gelcoat provides superior gloss, resistance to fading, and resistance to crazing • Deck coring windows are located at all hardware installations to maintain the watertight integrity of the deck coring • Molded in aluminum backing plates on all highly loaded deck hardware • Hull to deck joint is secured with 1/4-20 stainless machine screws installed on 4” centers through the full-length 6061 T6 aluminum backing plate imbedded in the hull flange. This method exceeds the recommended installation requirements of the ABS scantling for offshore sailing yachts. • Hull to deck joint is sealed with 3M 5200 adhesive sealant • Composite light RTM match-molded deck locker hatches assure strict thickness controls allowing accurate gasket seal of cockpit openings. Conventional construction uses single-sided moldings with painted raw ï¬�berglass underside. • Double lifeline gate at transom • Instrument pod integrated onto coach roof with convenient wire chase for instrument installations or additions Keel • 5,500 lb. State-of-the-art, high-lift ï¬�n design safety, and sail-carrying ability • 39% ballast/displacement ratio • Keel attached to hull with stainless steel bolts • Keel design features extremely low center-of-gravity (CG) bulb-design that produces overall VCG below designed waterline for extraordinary stability, • Epoxy-coated antimonial lead provides maximum stability Rudder & Steering System • Elliptical, foam-cored rudder blade with uni-directional E–glass skins • Oversize 304 stainless steel rudder post • NASA high lift, low drag rudder section for maximum control and performance • Emergency tiller supplied • Rack & Pinion steering system with 48-inch Commodore wheel offering excellent visibility both under sail and under power Interior • Structural ï¬�berglass longitudinal and athwartship grid bonded to hull and deck, utilizing high-strength epoxy adhesives and Plexus methylmethacrylate adhesives providing superior structural bonding of key components vs. conventional production construction techniques. • Ventilated panel varnished cherry passage doors with high quality locking latch hardware. Doors are mounted in laminated cherry doorframes • Aerospace adhesive technology used in the attachment of internal furnishings to further stiffen the overall structure • Curved laminated cherry locker and cabinet trim • Bulkheads and risers are pressure laminate or cherry-faced plywood • Ventilated, solid-stock varnished cherry panel locker doors with push button latch sets provide ï¬�xed latching for security in a seaway • Varnished cherry drop-leaf main cabin table to take up minimum interior space when not in use • Light weight composite construction utilized in lockers and cabinets • Cabinets and trim are varnished cherry • Cherry hull trim in forward cabin • Lockers and cabinets are ï¬�nished throughout and do not show raw ï¬�berglass, plumbing, electrical runs or raw plywood edges
