Abstract
An oil-spill-combatting water craft for recovering oil which is present on the surface of water. The water craft has at the water level at least one water inlet and, secured just behind this inlet, a collecting boom (2) which extends forwards and outwards, directing water to inside the craft, where there is a separating device (5) for the recovery of the oil from the water. In the water craft of this type the difficulty so far has been that, when the craft travels at a somewhat higher speed, water pressure in front of the boom tends to rise so high that some of the oil-contaminated water (3) "escapes" under the boom (2). According to the invention, this is prevented by arranging, for at least part of the water from which the oil has been separated and which discharges from the craft, an outlet just behind the collecting boom (2). For the rest of the discharging water there is preferably arranged an outlet which is located further towards the bow than is the inlet.
