Abstract: A floating flexible structure which can be filled with liquid is defined by pieces fixed by side seams. The seams are rendered buoyant by trapped balls. A vent in the upper part of the container has under it a net bag filled with balls to maintain gas passage. A transverse tube of netting rendered buoyant by balls maintains liquid flow for discharge through a hose.
