TECHNOLOGY Model tests of the SeaCoaster indicate the vessel is capable of high speeds and high efficiency. Fint Full-size SeaCoaster Built Air Ride Craft and Able Boat Inc. announced the construction of the first full-size commercial SeaCoaster. The new vessel is a catamaran-hulled Surface Effect Ship (SES), but reportedly differs extensively from the generic flex- ible seal SES. The SeaCoaster has a high length to beam blower pressurized air cush- ion under each sidehull. The two widely separated air cushions, thus formed, support 85 to 90 percent of displacement. The sidehulls have very fine entry wave slicing bows, designed to provide outstanding seakeeping. Seakeeping ability can reportedly be enhanced by a hydro- foil between the sidehulls forward. The SeaCoaster has flexible seals and no air cushion between its sidehulls. The SeaCoaster being built by Able is 45 x 18 ft. (13.7 x 5.5 m). The vessel is being built with advanced composites to provide high strength and low weight. The boat is being configured to be a 48-passenger, 45- knot ferry. The SeaCoaster hull shape is what reportedly makes for an inherently strong structure longitudinally, as there are four full-length keels, two on each sidehull. Transverse strength is ensured by four robust watertight bulkheads positioned fore and aft of the blower compartment, and of the engine compartment. The composite construction hull incor- porates E-glass skins and special- ized cores, and the specific mechani- cal properties of two uniquely dif- ferent state-of-the-art cores are be- ing integrated to provide an opti- mum design to meet ABS and U.S. Coast Guard certification. One is Core-Cell, a new generation of closed cell linear polymer foam core, by ATC Chemical Corp. of Buffalo, N.Y. The other is a high-strength, light- weight honeycomb structural core supplied by Nida-Core Corp. of 44 Hoboken, N.J. The two aluminum and stainless steel blowers are driven by a single Caterpillar 3054 diesel at 67 kW (90 hp) through a right angle T-gear. The two main propulsion engines are Caterpillar 3126 diesels at 260 kW (350 hp). The Caterpillar diesels were sup- jpl ap-plied and engineered for the appli- cation by Pantropic Power Products of Miami, and model tests show speeds with this power of more than 50 knots at moderate loads, and approximately 40 knots at full loads. wri«NiRnfr"iiRfr"i|ir",.«>n,i ••ar.ss •, h^UII ^ 1 i s. r— General arrangement of the Gentry Transatlantic vessel.
