Abstract: An apparatus for spreading the mouth of a bottom trawl comprising an array of flexible foil shaped kites that is capable of being mounted proximate to a wing of the bottom trawl, and wherein each of the kites in the array of flexible foil shaped kites has the same chord length and comprises: a middle kite foil section having an outer profile shape (preferably substantially a NACA 5319 shape) that is capable of assisting in spreading the mouth of the bottom trawl when in use, and having pockets extending longitudinally therethrough that house rope or wire of varying diameter, and a first and second endplate attached at each of a first and second distal end of the middle kite foil section respectively for maintaining a desired rigidity of the kite foil section, said first and second endplates having openings there through in communication with the pockets of the middle kite foil section, such that the rope or wire of varying diameter securely extends through said openings in the first and second endplate.
