Abstract: In the present paper, the target of our research is the study of operating capability, associated directly with the motion stability of an underwater towed vehicle, by taking into account the influence of constructive characteristics: hydrodynamic characteristics, gravity centre position, buoyancy centre position, position of connection point between the cable and the vehicle, vehicle buoyancy, and cable length. There were used the linearized differential equations for motion stability analysis, in first approximation. The stability domains of the above constructive characteristics for assuring an asymptotic stability of equilibrium motion are determined.

Keywords: motion stability, singularities, bifurcations, towed vehicle.
