A vessel as claimed in claim 1, wherein the or each at least one gyroscopic stabilizer includes a flywheel connected to a spin shaft such that the flywheel is able to spin about a spin axis, the spin shaft being connected to a gimbal frame, the gimbal frame being rotatably connected to the body of the vessel such that the gimbal frame is able to rotate about a precession axis, the spin axis being substantially perpendicular to the precession axis; and wherein the rotation of the gimbal frame about the precession axis is damped by a precession control device. 3. A vessel as claimed in claim 2 wherein the precession control device is controllable to reduce or maintain a distance between a point on the body of the vessel and a reference point. 4. A vessel as claimed in claim 1, wherein the or each at least one gyroscopic stabilizer includes a flywheel connected to a spin shaft such that the flywheel is able to spin about a spin axis, the spin shaft being connected to a gimbal frame, the gimbal frame being rotatably connected to the body of the vessel such that the gimbal frame is able to rotate about a precession axis, the spin axis being substantially perpendicular to the precession axis; and wherein the rotation of the gimbal frame about the precession axis is driven by a precession control device. 5. A vessel as claimed in claim 4 wherein the precession control device is controllable to reduce or maintain a distance between a point on the body of the vessel and a reference point. 6. A vessel as claimed in claim 1, wherein the suspension system is controllable so as to selectively increase or reduce the pitch, roll and/or warp stiffness. 7. A vessel as claimed in claim 1, wherein the at least two hulls includes at least one left hull and at least one right hull. 8. A vessel as claimed in claim 7, wherein the at least one support includes at least a left fluid-filled support between the or each left hull and the body and at least a right fluid-filled support between the or each right hull and the body, the left and right fluid-filled supports interconnected by interconnection means. 9. A vessel as claimed in claim 8, wherein the interconnection means is controllable to provide fluid communication or permit effective fluid transfer between the left and right fluid-filled supports such that the left and right fluid-filled supports provide substantially zero stiffness in response to roll and/or pitch motions of the body relative to the at least one hull. 10. A vessel as claimed in claim 8, wherein the interconnection means include control means for selectively limiting or selectively preventing said fluid communication or effective transfer of fluid. 11. A vessel as claimed in claim 10, wherein the control means limits or selectively prevents said fluid communication when said at least one gyroscopic stabilizer is not in operation. 12. A vessel as claimed in claim 7, wherein the at least one support between each hull and the body includes: at least a front left support and a back left support connected between the at least one left hull and the body;at least a front right support and a back right support connected between the at least one right hull and the body. 13. A vessel as claimed in claim 12, wherein the suspension system includes at least one interconnection means for providing an interconnection between at least two of said supports. 14. A vessel as claimed in claim 13, wherein the front left, back left, front right and back right supports each include at least a respective fluid filled compression chamber, the at least one interconnection means controllable to provide fluid communication or permit effective transfer of fluid between at least two of said fluid filled compression chambers to thereby provide substantially zero stiffness in a roll, pitch and/or warp mode of the front left, back left, front right and back right supports. 15. A vessel as claimed in claim 13, wherein the interconnection means include control means for selectively limiting or selectively preventing said fluid communication or effective transfer of fluid. 16.
