Abstract

The invention relates to a displacement body, especially a boat or a ship, comprising at least one blow device (12) for the structured placement of a gas between a displacement body and water. Said displacement body also comprises at least one catchment device (14) for at least partially reabsorbing the gas introduced by the blow device (12). The displacement body is characterised in that the catchment device (14) is arranged at a certain distance relative to the blow device (12) such that the structure of the gas introduced by the blow device (12) between the displacement body and water remains essentially the same until the reabsorbtion thereof by the catchment device (14). The invention also relates to a method for reducing friction on displacement bodies, especially on boats or ships.
