The shiny black engine compartment bottom is part of a single-piece liner that Outerlimits calls the E-glass monocoque X-frame structure. This runs bow to stern and comprises the stringers, transversals, and cabin and cockpit soles, plus the seat bases. It bonds to the hull and deck with adhesive, resulting in a boat built primarily from three pieces. All three pieces of the boat are laminated with epoxy resin, E-glass, Corecell foam and carbon and are post-cured in a large oven for optimum strength. In addition to producing a strong, light boat, the construction process is efficient. Outerlimits can finish an SV 29 in three weeks.
