Floating drive-on dry dock assembly

摘要

A floating, drive-on dry dock assembly for a small craft is assembled from two kinds of hollow floatation units, tall units and short units. The units are interconnected so that their top surfaces are substantially coplanar. The units are arranged to form two arms which support the hull of the craft on each side of the longitudinal center line of the craft. The entire length of each arm is made up of tall units except the distal end portions of each arm which may be made up of short units. The short units are able to flex downward as a craft begins to ride up on the dock because of the location of the connection between adjacent units. The tall units, however, cannot flex relative to each other nearly to the same extent as the short units, and so they form a stable generally planar surface. The distal ends of the arms are connected to each other by an upside down short unit. The short units are proportioned so that the uppermost surface of each is out of the water both when the dock is empty and when a craft is "parked" on the dock.
