    Abstract: A rope has a braided sheath that includes a spiraling strand having a greater pitch in comparison with a pitch exhibited by other strands of a coverbraid that encloses that rope's strength member core. The rope is useful for forming pelagic trawl mesh, and stronger for a given amount of material, as less drag, and exhibits the same or bettered lift when towed through water at trawl mesh angles of attack. The rope also is less costly to manufacture in comparison to known helix rope constructions.

    Abstract: Netting (15) includes mesh bars (26) made from twines (11, 13) which possess physical properties that vary, change or alternate along a series of collinear mesh bars (26). The non-homogeneous media obtained by arranging in this way mesh bars (26) having varying physical properties may be configured to dampen or attenuate vibrations in the netting (15) such as harmonic oscillations (resonance). Furthermore, twines (11, 13) that attenuate vibrations may be chosen that also reduce the amount of material required to make netting (15) which has strength similar to or greater than conventional machine-made netting (15). Due to reduced vibration, the improved netting (15) lasts longer than conventional machine-made netting (15), and reduces the possibility of injury to fish which escape through a trawl's mesh cell openings.

    Abstract: An improved trawl door (10) is adapted for being towed through water both at shallower and at larger angles of attack. The trawl door (10) includes at least one main deflector (24, 25) having a profile (46) formed by an inner surface (48) and an outer surface (47). The profile (46) spans a chord length “C” that extends along a Chord Direction Line (83) between leading and trailing edges (12, 14) of the main deflector (24, 25). The trawl door also includes at least one leading edge slat (20, 22) at least a portion of which is located in front of the outer surface (47) of the main deflector. The trawl door (10) in one aspect is characterized by an acute angle of inclination (91, 92) between a chord line (81, 82) of the leading edge slat (20, 22) and the Chord Direction Line (83) that is at least thirty-five degrees) (35°). The trawl door (10) in another aspect is characterized by having an aspect ratio of at least two to one (2.0:1.0).
