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 (&#x3b3;) of the appendage, allowing it to alter the lift (P), is dependent on an angle (&#x3b2;) formed between the bracket and the structure about the horizontal axis.

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.

A device for handling and towing a submersible object includes a tilting structure with a support, to pivot about a first axis parallel to a horizontal plane, and equipped with a guide device, a pivot connection about a second axis in a plane substantially perpendicular to the first axis, to allow a rotary part of the tilting structure to rotate relative to the support, the rotary part having the guide device, a stabilizing device to keep the rotary part in a deployed position relative to the support provided a torque of the relative pivoting between the rotary part and support about the second axis does not exceed a predetermined threshold, to allow the rotary part, equipped with the guide device, to rotate relative to the support about the second axis once a torque of relative pivoting between the rotary part and support about the second exceeds the threshold.
