A floating, drive-on dock formed from a plurality of floatation units each with a generally flat top surface, the floatation units being connected together so that their top surfaces are generally coplanar and horizontal, and each floatation unit having at least one side wall which faces an opposing side wall on an adjacent floatation unit, each floatation unit having a pivotable connection to the adjacent floatation unit, the connections being above the water line when the dock is floating freely and a fixed distance below the top surface of the floatation unit and enabling adjacent floatation units to rotate with respect to each other until the respective facing side walls come into contact with each other, a first group of the floatation units having bottom surfaces located substantially as far below the pivotable connection as their top surfaces are above the pivotable connection whereby they can rotate downward to the same extent they can rotate upward before the respective facing side walls come into contact with each other, a second group of floatation units having bottom surfaces located substantially closer to the pivotable connection whereby they can rotate downward substantially without limitation, said floating dock having a pair of parallel arms formed at least in part of floatation units from said second group of floatation units, and a bridging unit between said parallel arms, said bridging unit having a top surface which is above the water surface when the dock is floating freely; and a beam coupled to and positioned under the plurality of floatation units and positioned transverse to a longitudinal length of the dock, wherein the beam provides support to the plurality of floatation units, thereby reducing bowing and flexion when substantial forces are exerted, such as by large size watercraft, on the dock. view more

A floating dock assembly for a watercraft, said assembly comprising a plurality of floatation units connected to each other to form a base and a pair of arms extending from the base; the units of the base being joined to each other for limited relative movement so as to form a substantially rigid structure, and flexible connections between at least some of the units of each arm, the flexible connections between the units permitting each unit to pivot upward with respect to its immediately adjoining unit to a first limited extent and downward with respect to the same adjoining unit to a substantially greater extent. view more

A floating dock assembly for a watercraft, said assembly comprising a plurality of floatation units connected to each other to form a bow end portion, and a pair of arms extending from the bow end portion, the units of the bow end portion and the arms having top surfaces that are substantially coplanar to define a deck lying approximately in a plane, and floatation units connected between the arms having top surfaces below the plane of the deck to receive and guide a water craft being driven onto the dock and wherein the floatation units are generally square in plan view and have fasteners at their corners for connecting them to between one and three adjacent floatation units, some of the floatation units being tall units and having a first height, and some of the units being short units and having a second, shorter height, the floatation units connected between the arms being short units. view more
