Claim:
A floating platform having a flat cover element and a sealing element which is connected to the cover element, makes a sealing contact with a liquid surface during operation and encloses a closed cavity together with the cover element and the liquid surface or a bottom surface, in which cavity an overpressure which supports the cover element is producible by a compressed-air production apparatus, wherein the sealing element is flat and comprises at least one wall arranged circumferentially to the cavity and a sealing section arranged substantially perpendicular to the liquid surface during operation, the sealing section having a cross-sectional extension and having a perpendicular extension, the perpendicular extension extending in a direction perpendicular to the liquid surface, the cross-sectional extension being smaller than the perpendicular extension, and wherein a flexible membrane is provided as the circumferential wall; wherein the sealing section of the sealing element is weighted down by at least one ballast element; and wherein the sealing section of the sealing element comprises a plurality of regions that are each weighted down with a ballast element and that are each separated by a region of the sealing section of the sealing element which is free from the ballast element.
