1. A swim training device comprising:

  • a cable having a proximal end and a distal end;

    a harness for coupling the distal end of the cable to a swimmer in a body of water;

    a motorized drum mounted on a frame and coupled to the proximal end of the cable for winding the cable;

    an electrical controller electrically coupled to the motorized drum;

    a cable jacket coupled to the cable at the distal end for increasing the thickness of the cable;

    a cable sheave mounted on a sheave shaft parallel and proximal to the drum and upon which the cable lays;

    a guide roller shaft parallel to the sheave shaft and passing througha guide slot mounted to the frame;

    a guide roller, mounted on the guide roller shaft, proximal to and engaging the sheave with the cable traveling between the guide roller and the sheave within a space approximately equal to the cable diameter;

    a tension spring with a first end coupled to an end of the guide roller shaft and a second end fixed to the frame; and

    a limit-switch mounted to the frame proximally to the guide slot, engaging the guide roller shaft and electrically coupled to the electrical controllerwhereby upon activation of the motorized drum by the electrical controller the cable travels between the guide roller and the sheave and winds onto the drum until the cable jacket reaches the guide roller and sheave forcing the guide roller to move away from the sheave in turn displacing the guide roller shaft which in turn actuates the limit-switch changing the electrical state of the limit-switch whereupon the electric controller responds to the limit-switch change of electrical state by deactivating the motorized drum.
