Patent attributes
An amphibian (1) for use on land and water, comprising: a hull having a planing surface (2), and at least one retractable suspension apparatus (4) movable from a vehicle supporting position to a retracted position, comprising for each wheel (5), upper and lower suspension arms (8, 9) that are pivotably connected at inboard ends to a support structure within the hull; and are pivotably connected at outboard ends to a suspension upright (7). Upright (7) extends from a first, upper connection past a second, lower connection to a location (10) for a wheel hub mounting. The suspension upright when deployed in land use extends externally of the hull across a side face (2A) of the planing surface; while lower suspension arm (9) remains above the top of planing surface (2) throughout use of the amphibian on land. This suspension arrangement allows the hull to have no cutouts in its planing surface.
