The carrying portion includes at least two vertical shafts protruding from the transportation portion. The protruding end of each shaft is connected to, or received within, a watercraft engaging portion that tapers off in size as it extends further away from the transportation portion such that at least a section of each watercraft engaging portion deforms and compresses when received within one of the at least two apertures to create frictional engagement between the aperture and the section of the watercraft engaging portion. ## Claims ### Claim 1 A cart for a watercraft including at least two apertures provided therein, the cart comprising: a transportation portion; and a carrying portion comprising at least two vertical shafts protruding from the transportation portion, wherein the protruding end of each shaft is connected to, or received within, a watercraft engaging portion that tapers off in size as it extends further away from the transportation portion such that at least a section of each watercraft engaging portions deforms and compresses when received within one of the at least two apertures to create frictional engagement between the aperture and the section of the watercraft engaging portion. ### Claim 2 (depends on 1) A cart according to claim 1, wherein the watercraft engaging portion is conical in shape. ### Claim 3 (depends on 1) A cart according to claim 1, wherein the tapering end of the watercraft engaging portion is elongated. ### Claim 4 (depends on 1) A cart according to claim 1, wherein the watercraft engaging portion comprises a plurality of circular ribs. ### Claim 5 (depends on 1) A cart according to claim 1, wherein the watercraft engaging portion comprises a rubber wedge. ### Claim 6 (depends on 1) A cart according to claim 1, wherein the watercraft engaging portion is textured to further facilitate frictional engagement between the aperture and the section of the watercraft engaging portion. ### Claim 7 (depends on 1) A cart according to claim 1, wherein the transportation portion comprises at least one wheel connected to opposing ends of a strut of fixed width, where each vertical shaft is releasably connected to the strut such that it may be positioned anywhere along its width. ### Claim 8 (depends on 1) A cart according to claim 1, wherein the transportation portion comprises at least one wheel connected to opposing ends of an axle of adjustable width. ### Claim 9 (depends on 8) A cart according to claim 8, wherein the axle comprises at least two connectors, a portion of one of the at least two connectors sized so as to be received within a portion of another of the at least two connectors. ### Claim 10 (depends on 9) A cart according to claim 9, wherein the portion of the at least two connectors sized so as to be received within a portion of another of the at least two connectors has a measurement scale provided thereon. ### Claim 11 (depends on 9) A cart according to claim 9, wherein the axle comprises three connectors, two of the connectors being of equal size and shape, while a third connector is of such size and shape as allows the third connector to be received within the other two connectors. ### Claim 12 (depends on 11) A cart according to claim 11, wherein the third connector has a measurement scale provided thereon. ### Claim 13 (depends on 9) A cart according to claim 9, wherein a compression lock means secures the portion of one of the at least two connectors sized so as to be received within a portion of another of the at least two connectors and that portion. ### Claim 14 (depends on 13) A cart according to claim 13, wherein the portion of the connector not adapted to be received within the portion of another connector has a slit provided therein to facilitate the compression of that portion and its compressive engagement with the portion of the connector received therein when the compression lock means is in a locked state, ### Claim 15 (depends on 13) A cart according to claim 13, wherein the compression lock means includes a lever, where movement of the lever to a closed position causes the compression lock means to move to a locked state where compressive force is applied against the connector to which it is attached, and movement of the lever to an open position causes the compression lock means to move to an open state where the connector to which it is attached is able to move relative to the portion of another of the at least two connectors received therein. ### Claim 16 (depends on 15) A cart according to claim 15, wherein the lever has a contoured edge of matching profile to an external contour of at least a part of the remainder of the compression lock means such that, when the lever is in a fully closed position, the contoured edge of the lever mates with the external contour. ### Claim 17 (depends on 1) A cart according to claim 1, wherein each watercraft engaging portion includes a strap retainer and opposite ends of at least one strap are retained at respective strap retainers. ### Claim 18 (depends on 17) A cart according to claim 17, wherein the at least one strap is releasably connected together on an end-to-end basis by way of at least one connecting means, each connecting means having a protective cover. ### Claim 19 (depends on 17) A cart according to claim 17, wherein the at least one strap comprises webbing tape.
