Amphibian

Abstract

The present invention provides, with reference to FIG. 1 , an amphibian for use in land and marine modes comprising: a planing hull; three wheel stations, two of the three wheel stations being front wheel stations provided one on each side of and in the front half of the amphibian, and the third wheel station being a rear wheel station provided in a central region in the rear half of the amphibian; at least one wheel provided at each wheel station, each wheel being movable between a protracted land mode position and a retracted marine mode position; land propulsion means to propel the amphibian on land in the land mode, the land propulsion means comprising at least one of the wheels; and marine propulsion means to propel the amphibian on water in the marine mode, the marine propulsion means comprising at least two impellers or propellers provided one on each side of the rear wheel station.

209 . An amphibian having two front wheels, a single rear wheel, and a body; wherein seating is provided for at least one rider to sit astride the body, wherein a water jet unit is provided for propulsion in water and wherein the water jet unit is positioned ahead of the rear wheel. 
     
     
         210 . An amphibian according to  claim 209 , wherein the rear wheel is driven to power the vehicle on land. 
     
     
         211 . An amphibian according to  claim 209 , wherein the front wheels are driven to power the vehicle on land. 
     
     
         212 . An amphibian according to  claim 209 , wherein the water jet unit is longitudinally aligned with at least part of the rear wheel. 
     
     
         213 . An amphibian according to  claim 209 , wherein at least one deflector is provided in order to divert the output from the water jet away from said rear wheel. 
     
     
         214 . An amphibian according to  claim 213 , wherein the deflector is formed as a chevron shape to deflect water either side of the rear wheel. 
     
     
         215 . An amphibian having two front wheels, a single rear wheel, and a body; wherein seating is provided for a rider to sit astride the body, wherein a suspension connects the front wheels and the rear wheel to the body and the suspension is arranged such that the body can lean about a longitudinal axis. 
     
     
         216 . An amphibian according to  claim 215 , wherein a water jet unit is provided for propulsion in water and said water jet unit is offset from a central longitudinal axis of the body. 
     
     
         217 . An amphibian according to  claim 215 , wherein pontoons are provided either side of the rear wheel. 
     
     
         218 . An amphibian according to  claim 215  wherein an output nozzle of the water jet unit is located in a pontoon.
