Abstract: A body towed by a cable behind a ship and commonly referred to as a towfish, the towfish includes a structure configured to move through the water in a horizontal main direction and at least one appendage configured to generate on the towfish a downwardly directed hydrodynamic lift (P) when the towfish is moving through the water under the effect of the towing, the appendage being orientable so as to modify its lift. The towfish comprises a bracket capable of rotational movement with respect the structure about a horizontal axis perpendicular to the horizontal main direction, the cable being attached to the bracket. An orientation (γ) of the appendage, allowing it to alter the lift (P), is dependent on an angle (β) formed between the bracket and the structure about the horizontal axis.

Abstract: In the field of bodies towed behind a ship, commonly called fish, a fish comprises a supporting structure configured to move in water in a horizontal main direction, at least one appendage configured to generate a hydrodynamic lift directed downwards when the fish moves in the water under the towing effect, and a lock for reducing the hydrodynamic lift of the appendage.

Abstract: A device for handling and towing a submersible object installed on a ship, comprises: a tilting structure supported by a support, and able to pivot with respect to the support about a first axis parallel to a plane to extend horizontally, the tilting structure equipped with a first guide device allowing the cable to be guided, a pivot connection about a second axis situated in a plane substantially perpendicular to the first axis of rotation, arranged to allow a rotary part of the tilting structure to rotate with respect to the support, the rotary part equipped with the first guide device, a stabilizing device arranged to keep the rotary part of the tilting structure in a deployed position with respect to the support as long as a torque of the relative pivoting between the rotary part and the support about the second axis is below or equal to a predetermined threshold, and to allow the rotary part, equipped with the first guide device, to rotate with respect to the support about the second axis once a torque of relative pivoting between the rotary part and the support about the second exceeds the threshold.
