THE COURSE STABILITY OF TOWED BOATS--WHEN THE MASS OF TOW ROPES IS CONSIDERED

Previous papers investigated the problems of the course stability of towed boats in Vols. No. 42 and 43 of this journal, but the mass of the tow ropes was neglected. In this paper, the property of tow ropes has been taken into consideration in the following cases: 1) elastic rope, 2) transverse vibration of the towline with linear density, 3) catenary rope which is free from the influence of the speed of flow, 4) catenary rope under the influence of the speed of flow, 5) transverse vibration of the catenary rope and 6) the effect of increasing the resistance of ships. In the above cases, the course stability generally increases compared with the taught tow line, but in the cases (3) and (4), it only effects the course stability in the direction which the tugboat moves. Consideration of the transverse vibration of the catenary rope is equivalent to the case (2) with nonlinear distribution of linear density.
