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.
A water craft including a chassis portion, at least four water engaging means and interconnection means,
A water craft including a chassis portion, a plurality of water engaging means, and at least one damping means, wherein each damping means is associated with a water engaging means and each damping means includes a first damping member and a second damping member arranged to move relative to the first damping member when the water engaging means moves relative to the chassis, the damping means being arranged such that relative movement between the first damping member and the second damping member causes absorption of energy from motions of at least one water engaging means relative to the chassis portion.
