"Deflector device for use with a tow line between a ship and towing a trailer in the water behind the vessel, and method of performing a survey su00ecsmico Marino".A deflector device for use with the tow line between a seismic survey vessel and a trailer, in particular a line of drag or a system of drag lines.In the water behind the vessel comprises a vertically oriented body in the shape of a wing to produce a force to the side when it is towed through the water.And a tie of trailer adapted to connect the body in the shape of a wing to the line of the trailer.The tie includes first and second switching elements connected between the tow line and respective points spaced lengthwise along the high pressure side of the body in the form of aThe wing.The body in the shape of a wing includes one or more elements of the fluctuation to make it floating way slightly positive and the length of at least one of the switching elements is adjustable throughThe remote control for tilting the body in the shape of a wing.This provides the force to the side, a vertical component, and so allows remote control of depth of the deflector device, as well as the lateral displacement from the vessel.
