    摘要： The present invention relates to trawl doors used in trawl fishing, including shallow water trawl fishing applications, deep water trawl fishing applications, bottom trawl fishing applications as well as at pelagic trawl fishing applications, and to seismic surveillance line spreading and spreading of other items towed in water. The present invention provides a hollow trawl door, said hollow trawl door having one or more chambers and an airfoil cross-section, comprising - a first side panel (1) having a curvature forming the back surface, - a second side panel (2) having a curvature forming the front surface, and - an upper panel (3) forming the top of the trawl door and a bottom panel (4) forming the bottom of the trawl door, wherein the first side panel (1) and second side panel (2) are connected at a leading edge and at a trailing edge of the airfoil, and wherein the trawl door comprises one or more openings (5) to allow water to flow in and out of the trawl door.

    摘要： A trawl door, deflector, vane or paravane (40) constructed with adjustable panels (22, 23, 24) and driving units (25) for control the water flow through the spreading device during towing through the water with remote control where driving units (25) are used to adjust the position of the panels control the water flow through the spreading device and maneuver the spreading device in optimum position in the towing direction, horizontally or vertically, the panels are adjustable independently to give enhanced performance of the operating systems, fishing trawl or seismic survey system, without having to pull the system to the towing vessel to adjust manually.
