A SMALL-WATERPLANE-AREA-SINGLE-HULL SHIP WITH STABILIZING HYDROFOILS (SWASH):SEAKEEPING CHARACTERISTICS AND CALM WATER PERFORMANCE

摘要

Stability, seakeeping and resistance characterization experiments have been conducted on a novel ship (SWASH) which incorporates a single, small waterplane area hull and outrigger surface piercing hydrofoils for stability. Comparisons are provided between pitch and heave transfer functions for SWASH and those of a small waterplane area twin hull (SWATH) and a conventional monohull. Root-mean-square motions in head Sea States 5 and 6 are also compared for these vessels, as well as effective horsepower (EHP) in calm water.
