A MULTI-FOIL LIFT FORCE CREATOR FOR A FISHING TRAWL

摘要

A multi-foil lift force creator (1) for a fishing trawl is disclosed, said multi-foil lift force creator comprising a plurality of hydrofoil elements (2) aligned in a stacked manner and designed to be arranged between and attached rigidly at both ends to a spherical buoyancy element (9) for being mounted on a fishing trawl head rope (11), wherein the hydrofoil elements are shaped to deflect the water during towing of the trawl net (12) in such a way that the hydrodynamic force thereby created complements the buoyancy force from the buoyancy elements, and wherein, rather than having butt ends, the hydrofoil elements join smoothly to multi-foil end caps (5) fitting tightly around the two buoyancy elements at the ends of the multi-foil lift force creator, respectively. Furthermore, a multi-foil lift force creator assembly comprising such a multi-foil lift force creator and the use of such multi-foil lift force creator assemblies during trawling operation are disclosed.
