In this paper several hybrid surface ship concepts are described and their estimated speed-power and range performance compared under calm and rough water conditions. The concepts analysed are the Small Waterplane Area Single Hull (SWASH) Ship, Hydrofoil Small Waterplane Area Ship (HYSWAS), Large Hydrofoil Hybrid Ship (LAHHS), Hydrofoil Air Cushion Ship (HYACS) and Small Waterplane Area Air Cushion Ship (SWAACS). All concepts investigated are of 2,000-ton (2,032-tonne) displacement having various combinations of buoyancy, foil lift or powered static-lift from an air cushion. Analysis showed that HYSWAS and LAHHS with about 70% buoyant lift and 30% dynamic lift are expected to have generally favourable characteristics in both calm and rough water over a broad speed spectrum leading to relatively good speed and range performance. These concepts therefore, appear to be promising configurations for future consideration. However, for special purpose missions, where for instance only a segment of speed spectrum is dominant or rough water operations are not anticipated, other hybrid forms may show potential and might be pursued further.
