The stringer system in every Parker is constructed of "Select Boat Ply," a solid fir plywood specifically designed with extra laminates for boat building, and bedded in the hull using a polyester and fiberglass bedding compound so that there are no voids between the stringers and the hull. After the stringers are securely bonded in place, they are totally encapsulated in fiberglass and resin, preventing moisture intrusion and guaranteeing the long life and strength for which Parker boats are known.
The term "Parker Double-Hull Construction" comes from the construction technique used to make the cockpit-sole of every Parker an integrated structural part of the Parker hull. The same wood material used in the stringer system is hand-fitted to the hull and stringers, encapsulated in fiberglass and resin, mechanically fastened with stainless steel fasteners, and then chemically bonded to the hull with fiberglass. During this process, the sub-deck wiring and piping is installed. The fuel tanks, constructed of 5052 marine aluminum alloy zinc-chromated to discourage corrosion, are mechanically fastened to the stringers using stainless steel fasteners and foamed in place. Then fiberglass-encapsulated chambers in the hull are injected with two-pound density foam, which becomes a structural strengthening unit and sound dampener while providing flotation.
