The hull is as close to overbuilt as you can get. The manufacturer calls its -building process “monolithic construction,” and it uses AME 5000 vinylester resin throughout the process, with U.S.-manufactured nonwoven glass and double layers of Divinycell coring vacuum bagged for strength without excess weight. All areas where through-hulls, struts or rudder posts extend through the hull receive additional reinforcement before the full-length stringer system and a comprehensive thwartship stringer grid get glassed in place, followed by four main composite bulkheads, a crash bulkhead and hull side beams. The hull is then baked so the laminate is completely cured. Composite floors and soles are bonded to the stringer system and glassed to the hull using West System epoxy before the house, bridge and skybridge are glassed in place to create a single, extremely strong monolithic structure. When finished, the boat isn’t the lightest or the heaviest in its class, but it is arguably the strongest. It’s also remarkably quiet, due to the composite construction and the comprehensive sound program that’s a part of every boat Sea Force IX builds.
