Research in Advanced Surface Effect Ships
Abstract
Research is conducted toward development of high payload-fraction surface craft capable of efficient high-speed (50+ knots) coastal/short sea transport of passengers and cargo; other desired characteristics included shallow draft, steadiness, ease of reconfiguration, shock resistance and survivability in high threat areas. An experimental 42 ft lwl (50 ft oa) air-cushioned, composites constructed, catamaran is designed, built and tested to serve as a demonstrator and test bed for proprietary technology that could deliver the desired capabilities. The research vessel exhibits 25% to 50% lower hull resistance than comparable conventional fast craft, and moderate scaleups of the research vessel are estimated to be capable of full load speeds in excess of 50 kts. The craft handles and maneuvers well and exhibits very limited vertical accelerations in tested conditions up to sea state 4. Impressive fuel economy and payload capacity are projected for various scaleups (up to 125 ft length oa) of the test vessel, including very long range patrol/rescue/fireboat and 250 and 500 nm freighters, lighters and transports. Scaleups are favorably compared to Stiletto and LCAC.
