Amphibious vehicle 1 has at least two, preferably three, longitudinal vee sections 40 to 42 in its hull 2 . Retractable wheels ( 21 , FIG. 3 ) are provided; these may retract into discontinuities 8 to 11 in the hull. The wheels are retracted above the lowest point of the hull for marine use; and are protracted at least partly below the lowest point of the hull for land use. Where three vee sections are provided, the central vee 40 may depend lower than the side vees 41, 42 ; or vice versa. The hull may be a cathedral hull. The hull may have a deadrise of between 10 and 25 degrees. The vehicle ground clearance may be adjustable, for example from 0.10 m to 0.50 m. A four wheel drive power train may be provided, as shown in FIG. 4 ; for example, with a longitudinal engine 50 , PTO 60 , transmission 70 , and transfer case 80. |
