1. An amphibious vehicle including:
a boat hull having a substantially transverse forward bulkhead spaced from a stem and also having a substantially transverse aft bulkhead forming a transom; a pair of undercarriage assemblies associated with each of said forward and aft bulkheads, each undercarriage assembly having a linearly extendable strut assembly and a carriage wheel assembly at a lower end of said extendable strut assembly, a forward pair of said undercarriage assemblies each being supported on a forward face of said forward bulkhead and spaced about a centerline of said hull with each extendable strut assembly being selectively operable to move a carriage wheel of said carriage wheel assembly between (i) a deployed position so as to be operable for supporting said hull on a surface and (ii) a retracted position, the spacing of said forward pair of undercarriage assemblies and the length of said extendable strut assemblies being selected to locate said carriage wheel above a planing waterline of said hull in said retracted position, an aft pair of said undercarriage assemblies being supported on an aft face of said transom; and a pair of recesses, each said recess spaced athwart said stem to leave the stem unbroken, each said recess formed in a respective side of said hull and having received therein a portion of a respective undercarriage assembly of said forward pair of undercarriage assemblies, each said recess also being watertight to the inside of said hull and having an end defining an opening in said hull which is located entirely above said planing waterline of said hull. |
