From the above result, the Kite Towing System has the function of suppressing the "whirling motion" and reduces the snap tension that occurs at the towing rope. We also come to know that the tension on the respective ropes decreases because the two ropes are used.

　

The future research remains are closer to the actuality. Our rope restoring force model is the linear spring model. Because of this, calculation time is reduced and length of the towing rope, the balancing position could have been maintained easily to the neutral position. In practice, the calculation with the use of non-linear spring model is more natural and necessary. We will continue our research by further developing calculations in such aspects and at the same time the quantitative model tests or actual sea trials should be performed and compared with the result of this study.
