TL;DR: In this paper, the results of dynamic and steady-state cable simulations are used to show that a towed system can behave in either one or both ways on entering a turn, in a turn of small radius the system effectively collapses resulting in a large increase of fish depth and cable tension.

TL;DR: In this paper, the response of a neutrally stable fish to disturbances in the ship motion was investigated using simulation in two dimensions of a fish towed on a faired cable, and it was shown that the overall amplitude of motion of the fish is proportional to the sine of the angle made by the top of the cable with the horizontal.

TL;DR: In this article, the mathematical model used as a basis for predicting body and cable dynamic behaviour under seagoing conditions was validated using measurements of towed body motion in a laboratory towing tank.

TL;DR: In this paper, the authors described the hydrodynamic forces and moments that act on a towed fish and related them to fundamental static and dynamic towing characteristics, and showed that decreasing the fin height almost to the point giving neutral stability in pitch, the fish maintains almost constant pitch attitude while being forced to heave or surge by ship motion transmitted down the cable.

TL;DR: In this paper, the lateral motions of roll, yaw and sway of a heavy towed fish are investigated, and it is shown that very careful adjustment of fin size can reduce the amplitude of yawing motion by a factor of about 3.
