The SJ48 combines lobster boat styling with state-of-the-art design, engineering and composite construction. Her hull provides comfort and sea keeping in difficult sea conditions yet allows for higher speed cruising in calm to moderate sea conditions. The SJ48 provides a safe, comfortable, dry ride in the no-nonsense environment of any ocean or waterway.
At 51’-10” L.O.A. x 15’-6” Beam, the SJ48 offers a premium level of interior space in a highly functional interior/exterior layout. The SJ48 offers unmatched care and craftsmanship in her interiors, fit, finish, joinery and systems.
The SJ48 hull has a traditional flared bow with fine entry and tumble home aft, complemented by her hydro-dynamically efficient underbody. The SJ48 hull is formed using a Kevlar/E-glass and Corecell foam core composite vacuum 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. Her resin 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. 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 PVC and Corecell foam core composite.

The deck is a one-piece vacuum 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 stainless steel mechanical fasteners.
