PROBLEM TO BE SOLVED: To provide a vessel capable of being land transported by towing without using any dedicated trailer. SOLUTION: A coupling means 40 for coupling the hull 11 of a motorboat MB with a towing vehicle is installed in the front part of the hull 11, and a supporting means 20 and a driving means to displace the means 20 are installed in the rear part of the hull 11. At storage on land, the supporting means 20 is put in the land transport attitude in which wheels 32 protrude down from the hull 11, and a caster 50 connected with the coupling means 40 is fixed in the upright attitude so that the hull 11 is borne by three points. At the time of towing, the coupling part 40 is coupled with the towing vehicle and the caster 50 is set in the retracting attitude, and towing is conducted. When cruising on water, the coupling part 40 and caster 50 are removed from the hull 11, and a handle is turned from on board the vessel to retreat the wheels 32 backward, and thereby water resistance resulting from the wheels 32 can be avoided, and the vessel can work without impairing its function as motorboat.
