the invention relates to a personal watercraft carrier for transporting personal watercraft such as jet skis , wave runners and the like , into and out of the water . the personal watercraft carrier has a conventional carrier frame , which includes rail supports for the watercraft , and a tongue having a handle for pushing or pulling the carrier , and is supported by one or more axles , which rotatably mount large - surface wheels . the wheels support the weight of the watercraft and carrier while traveling over soft terrain e . g . sand . the wheels are constructed so that the carrier as a whole has neutral or negative - buoyancy . as a result of the neutral or negative - buoyancy of the carrier , the carrier can drop away as the depth of the water increases , thus enabling the watercraft to be easily removed from the carrier . similarly , the carrier can be positioned below the surface of the water for retrieval of the watercraft . the watercraft can then be easily floated into position over the carrier for retrieval . in one embodiment , the wheels are open so that water freely flows into the wheels . the large - surface wheels are typically constructed of a heavy - duty , dense plastic or metal and have a cylindrical rim and a disk or a number of spokes extending perpendicularly inward from the rim with gussets to the cylindrical surface . the carrier also includes rails that can be extended with a tongue - and - groove construction to accommodate longer watercraft , or multiple watercraft , on one carrier .
