Claim 1

In an apparatus for the transportation of loads, particularly boats, comprising: a. a pair of inflatable load bearing wheels; b. said wheels mounted on a common axle; c. said wheels extending through substantially the entire width of the load; d. said wheels having an assymmetrical profile such that in the proximity of one of their extremities, there is a circumference which is smaller than the circumference adjacent the other extremity; e. said wheels mounted on said common axle having their smaller circumferences adjacent while the larger circumferences are mounted in the proximity of the extremity of said axle which carries them; f. a pair of auxiliary wheels of non-deformable compositions, said wheels of approximately the same diameter as said inflatable wheels; g. said auxiliary wheels having a thin profile; h. said auxiliary wheels mounted on said common axle at either extremity of said axle while said inflatable wheels are mounted on said axle interior of the auxiliary wheels; i. a load supporting structure above said wheels and rigidly supported by said axle at either extremity of said axle and at the center of said axle between said inflatable wheels.

Claim 3

An apparatus for the transportation of loads, particularly boats, comprising: a. a pair of inflatable wheels mounted on a commOn axle, b. each of said wheels having a broad tread and having an elliptical profile, c. a pair of auxiliary wheels of non-deformable composition, said wheels of approximately the same diameter as said inflatable wheels, d. said auxiliary wheels mounted on said common axle at the extremity of said axle, while said inflatable wheels are mounted on said axle interior of the auxiliary wheels, e. a boat supporting structure above said wheels rigidly supported by said axle, f. said support structure comprising two arches, each having their ends terminating at and journaled on the extremity of the axle, g. said arches rotatable on said axle, h. each of said arches held in load-bearing position by a transverse support beam.

Claim 4
