The present invention provides, with reference to Figure 1, an amphibian operable on land and in/on water. The amphibian comprises a planing hull, at least one retractable wheel, the at least one retractable wheel being retractable from a protracted land engaging position when the amphibian is operated on land to a retracted position when the amphibian is operated in/on water, at least one prime mover for providing power to drive, directly or indirectly, the amphibian on land and/or in/on water, and at least one steerable wheel which is, at least when the amphibian is operated on land, connected directly or indirectly to a steering control device operable by a driver to steer the amphibian. In addition the present invention provides that either i) the steering control device is moveable between at least two distinct laterally spaced positions across the width or beam of the amphibian; ii) the amphibian comprises side-by-side seating; iii) the amphibian comprises a roll over protection system; iv) the amphibian comprises an open cargo area cargo or truck-like bed; v) the amphibian comprises two seat belts and three seat belt buckles or buckle positions, or two seat belt buckles or buckle positions, and three seat belts; vi) the amphibian comprises a footwell area having no transmission tunnel; vii) the amphibian comprises a footwell and seating area configured so as not to impede or restrict driver and/or passenger entry via one side of the amphibian, egress from the other side of the amphibian, and through movement therebetween; viii) the amphibian comprises a positive buoyancy system and/or deployable righting system; or ix) the amphibian comprises an interlock or safety system which prevents operation/activation of at least one driver or automatically controlled parameter of the amphibian unless sensing/determining a first condition has been satisfied.
