An amphibious craft has a hull and wheels for supporting the hull on land. At least one pair of the wheels is driven from a motor on the craft. The driven wheels (13) on one side of the craft are driven independently from those on the other side of the craft. To this end respective drive transmission mechanisms (28, 29, 31; 33, 34) are provided for the wheels to transfer power from the main drive shaft (15) to the wheel stub axles (20). Each drive transmission mechanism is housed in a watertight casing which also acts as the main strut for the wheel when in use. The wheels are retractable into respective compartments in the hull preferably without breaking the strength of the keel. |
