ABSTRACT:
A tent structure of light-weight reinforced plastic sheet covers the hatch of a barge for weather protection of contents. The cover is stored in compact form aboard the barge for quick erection by a winch system when use is required. The array is secured over the coaming by fastening the cover to the deck at a series of positions with claw hook and chain assemblies. By erecting stored ridge poles to extend above the coaming, the cover thereover provides a pup-tent form which sheds water as a roof, permits loading above the coaming level, and permits loading or unloading in foul weather from the side. Very light-weight reinforced plastic permits a low cost throw-away type assembly with little manpower necessary for erection and produces maximum cargo capacity pay-load and lower maintenance cost by replacement of heavier steel hatch covers.
