The SJ40 hull has been designed and computer modeled to be both handsomely styled and capable in a broad range of sea conditions. The traditional flared bow with fine entry and tumble home aft is complemented by the hydro-dynamically efficient underbody. Tooling for the entire boat was modeled and cut by a computer controlled 5-axis router creating the most fair and precise parts available in the industry today. The SJ40 IPS hull is formed using a Kevlar® / E-glass and Corecell® foam core composite infused with vinyl ester resin. Dupont Kevlar® / E-glass hybrid is used to greatly increase the strength of the hull against damage caused by impact. The infusion process yields strong lightweight parts with high glass to resin ratios. The core is removed and replaced with solid glass and extra laminations in areas of major penetrations and high stress. Three composites watertight structural bulkheads separate the hull into damage control zones with dedicated bilge pumps. Structural bulkheads are built using Corecell® foam core with E-glass skins infused with vinyl ester resin. Longitudinal and transverse stringers are an E-glass Corecell® foam core composite. The entire structure of the boat is built using wood free composites. The hull is painted in the owner’s choice of Imron LPU colors.
The deck is a one piece infused composite molding using E-glass and Corecell® with vinyl ester resin. The hull is joined to the deck using an engineered flanged box joint and is bonded using a high strength adhesive with mechanical fasteners. This provides a permanent, watertight hull/deck joint.
