Abstract: A water craft (77) is disclosed which includes a chassis portion (78), at least four water engaging means (30, 34, 38, 42) and interconnecting means (94, 96, 98, 100, 102, 104, 106, 108, 110, 112, 114, 116, 118, 120, 122, 124, 126, 128, 130, 132). Each water engaging means is connected to the chassis portion (78) and is moveable in a substantially vertical direction relative to the chassis portion (78), and the interconnection means is arranged to functionally link the at least four water engaging means (30, 34, 38, 42) such that during use the chassis portion is encouraged to maintain an orientation which is substantially constant relative to the average plane of the water surface, even when the water surface is undulating and the water engaging means (30, 34, 38, 42) are not all disposed in the same plane.
