Abstract
A two wheeled planing amphibian (10) has a hull (20), bow (24), front wheel (30) and rear wheel (40). Front suspension (32) and rear suspension (42) are retractable, separately or simultaneously. Front wheel (30) may retract vertically or rotationally. Steering is by handlebars (50), link (54), and forks (36). Front wheel (20) may be located outside the hull in both protracted and retracted positions. The underside of hull (20) may be continuous in both land mode and marine mode along and across its centreline from the bow to the rearmost underside point on the hull along the centreline; or from the forwardmost underside point on the hull when it is planing at its lowest speed to the rear. There may be no wheel closures attached to the hull. A wheel bay (22), which is open at its top side, may be provided to allow rear wheel retraction.
