PORTABLE, PUMPLESS LIQUID WATER WEIGHT BALLAST SYSTEM

摘要

A portable, pumpless water ballast system can be constructed of a flexible water-proof membrane molded or formed of welded panels to make a desired shape, such as cube-shaped when filled with water. Along the top side is an opening for filling the container. A water-proof closure is provided in the opening to prevent water leaking out. An air release valve can be installed near the top area of the container's top or side panels. A handle or strap can also be provided on one or more of the adjacent sides of the container. A plastic threaded drain and closure can be provided on one or more sides to allow for emptying of the container or to attach other features like a hose or other accessory.
