A safety system and method of use is provided for a tow cable handling system. In use, the cable is from a winch and onto a sheave where a cable tension surge is transmitted to a meter and onto a software element. The software of a controller determines torque needed from a motor to increase winch speed to unreel cable to relieve the surge but not too much that the cable will unreel off the winch. Once the surge concludes, the motor reverses and decreases speed of the winch. If the tension surge is transient, then the motor can increase the winch speed and then slow down the winch before the cable completely unreels. The sheave is suspended by a spring and a dashpot for an over-damped response to increase the time for the winch to speed up to an acceptable speed.
