A novel barge structure for transporting fresh water from one marine environment location to another is described having critical parameters. The barge is constructed of flexible material and preferably is filled to less than 50 percent of its capacity, typically greater than about 25,000 tonnes, so as to float with flat upper and lower surfaces and to have a relatively shallow depth as compared with its length and width. The flexible nature of the structure enables waves to be accommodated without significant stresses which otherwise would require the use of high strength materials. A system of heavy straps acts to prevent propagating rips and to distribute the concentrated tow force over the bag.

[ What I claim is:] [1.] A flexible marine barge structure, comprising:a unilocular hollow flexible bag having a generally planar configuration and streamlined in shape in plan view and constructed to receive a cargo of an aqueous medium less dense than sea water, so that said barge floats in sea water when containing said cargo and to a proportion of the capacity of said bag structure such that, when said barge floats in sea water with said cargo, the bag has substantially planar and parallel upper and lower surfaces and a length-to-depth ratio of from about 2:1 to about 50:1, a width-to-depth ratio of from about 2:1 to about 20:1 and a length-to-depth ratio of from about 1:1 to about 20:1,said streamlined shape being defined, at the bow end, by a pair of opposed arcs of a circle intersecting at the bow and, at the stern end, by a pair of straight lines intersecting at the stern and formed tangent to the arcs of a circle, so that the angle between the straight lines at the stern is approximately one half the angle between the area of a circle at the bow.
