The object of the invention is to provide a small waterplane area ship capable of efficient operation at moderate to high speeds as defined by Froude numbers greater than 0.8. The ship (20) comprises an above-water hull structure (22) supported by water piercing struts (28, 30, 34, 36) which may terminate in buoyancy pods (29, 31, 38, 40). The struts may be subtended by streamlined transverse foils (32, 42) extending between the struts. These foils (32, 42) and/or pods (29, 31, 38, 40) have short stream wise lengths and provide major buoyancy for the ship (20), reducing wave resistance at moderate to high speeds. |
