ABSTRACT:
A deflector (2) for installation in the tow-line (4, 5) between a towing vessel and a tow which is located in the water, e.g. a cable with seismic sources or a seismic source array, is suspended by a float (1) and has a fitting (9) therefrom having a tow-point (7) near the front part of the deflector connected to the tow-line (4), and an attachment point (8) to the rear of the deflector for further connection thereto of the rear part of the tow-line connected to the two. In order to be able to locate the deflector in a desired position in relation to the towing vessel and compensate for alternations in the effects of forces from the tow or vessel in addition to movements in the water, the tow-line (5) which leads on to the actual tow from the deflector body (2) is attached (8) to the deflector via a pivotable lever (10) which is situated at the same height as the lifting force center of the deflector body. The tow-point (7) for the tow-line (4 ) is provided at one lateral surface of the deflector body (2) in front of the vertical center line thereof. An additional deflector wing (18) may be incorporated in the rear part (5) of the tow-line.
