  • that said towing cable is coupled to the towing vessel through a control means for varying towing cable length from the towing vessel to said at least one deflector;

    that the control means are coupled to the calculation means for adjusting said towing cable length depending on said deviations in said second position, thus to counteract corresponding deviations in movement of said at least one deflector.
