The invention refers to a method which consists in that a specific number of elements, hereinafter referred to as the arms (2), are put into motion in the plane perpendicular to the fluid flow direction, and project from the hull of the watercraft at a specific part of their length. Each of the arms (2) is propelled with an individually designated motion generator (3) of a variable amplitude (A) and frequency (f) of displacements, controlled by the electronic central control unit (4). |
