A boat hull washing apparatus includes a left structure and a right structure, one or more brushes arranged to wash a hull of a boat positioned between the structures. The apparatus is provided with a boat positioning assembly that includes a left and a right boat pushing device. The left and right boat pushing devices are attached to left/right structures respectively. The left boat pushing device is arranged to bias a boat, located between the left and right structures, away from the left structure, and the right device functions similar away from the right structure. In this way, the pushing devices are arranged to hold the boat in a lateral position. Using this arrangement of the left and right pushing devices to bias the boat away from the left and right structures, respectively, a single force generating unit is connected to both pushing devices.

A personal water craft (PWC) dock has a molded platform, the platform having a main section with its upper surface contoured to provide an elongate recess extending the length of the platform. The recess is shaped and dimensioned to receive and support the hull of a PWC, the recess being asymmetrically located towards one side of the platform. A raised walkway deck section extends the length of the platform and is located towards the other side of the platform, the walkway deck section being located over a buoyancy chamber. The molded platform is configured at each end of the recess for selective installation of a centering roller or a bow stop as desired for convenience when siting the PWC dock and its walkway deck section in relation to a main dock.
