Apparatus for skimming liquids, such as oil, having a specific gravity less than that of water from the surface of a body of water including a pair of laterally spaced hulls supporting a basin between them and a skimming edge immediately ahead of the basin, the hulls including fore and aft chambers and means for admitting or expelling water independently into or out of each chamber to select the level and the fore and aft tilt of the hulls relative to the surface of the body of water so as to enable skimmed liquid to pass over the skimming edge and into the basin.
