Spreading device trawl door with at least four foils with edges that align on a common center point

A spreading device for trawl fishing, seismic survey operations and other water activities where it is desirable to keep distance between two sides of a towed device,

• the spreading device having at least one section,
• where each section has at least four foils,
• in use an inner set of the at least four foils comprising at least a first forward foil and a first rearward foil and an outer set of the at least four foils comprising at least a second forward foil and a second rearward foil,
• where all the at least four foils have a front surface and a rear surface,
• the surfaces each being defined by a front edge and a rear edge and two side limitations,
• where the front edge of the first forward foil and the front edge of the second forward foil are arranged on a first radial extending from a center point where the rear edge of the first forward foil and the rear edge of the second forward foil are arranged on a second radial extending from the center point and
• where the front edge of the first rearward foil and the front edge of the second rearward foil are arranged on a third radial extending from the center point and where the rear edge of the first rearward foil and the rear edge of the second rearward foil are arranged on a fourth radial extending from the center point.
