Abstract: A diving fairing to be used with a front-end rigging in a seismic survey system, the diving fairing including a body extending along a longitudinal axis X; a first through passage formed along a transversal axis Y, which is perpendicular on the longitudinal axis X; and a second through passage formed along the transversal axis Y, offset from the first through passage.

Abstract: A diving fairing to be attached to a line of a seismic survey system, the diving fairing including a body extending along a longitudinal axis X and having a passage formed along a transversal axis Y, which is perpendicular on the longitudinal axis X; and a first weight located on the body. The body is symmetrical relative to the longitudinal axis X and the first weight is distributed along the body asymmetrically to exert a torque relative to the passage that creates a non-zero angle of attack of the body with a horizontal direction.
