A planing amphibian 10 comprises a hull 12 and a pair of wheels 20 mounted on a retractable suspension assembly 22. At least one land drive and at least one separate marine drive 40 may be provided. A wheel retraction mechanism is provided for moving the wheels between a deployed wheel position for use of the amphibian on land (figs. 2 and 4) and a retracted wheel position above a waterline of the amphibian for planing on water. The suspension assembly comprises suspension arms 24 outside the pair of wheels 20 so that the wheels 20 lie between the arms 24. Marine drives 40 may be inboard of the wheels (fig. 2) or outboard thereof (fig. 4). An axle 28 with a differential (29, Fig 3) may be provided. Suspension and retraction may be provided by means of torsion bars (30, Fig 3) with a cranked central section (54, 55, Fig 3). |
