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.
