A floating, drive-on dock (27) for personal or commercial watercraft is assembled from a combination of hollow, air-tight floatation units (12). The dock includes a beam formed from a plurality of floatation units (29a-e) coupled together positioned underneath and attached to the dock (27) to provide transverse support and lift for the floatation units (12a) and thereby reduce bowing or flexion when substantial forces are exerted, such as by large size watercraft, on the dock surface. Additionally, at least one of the floatation units (29a-e) that form the beam, includes an aperture so that the buoyancy of that unit can be adjusted.
