ABSTRACT:
A safety release for water skiing tow lines comprising a U-shaped body having a rearwardly facing slot therein, a mounting bracket for securing the device to a ski pylon, a bolt arm pivotally secured to the body which extends across the slot when the arm is in a vertical position so as to engage the terminal loop of the ski rope. The loop retaining bolt arm is pivotally mounted on the body and is pivotable rearwardly from a first position substantially normal to the plane of the slot opening to a second position substantially free of the slot opening. A manually operable extension is affixed to the bolt arm to move the arm in a forward direction from the second position to the first position. A lever is pivotally mounted on the body to engage the bolt arm to form a bar-like assembly which extends transversely of said opening. The lever is pivotable from a first position wherein an end thereof abuts the end of the bolt arm to releasably hold the bolt arm in its first position, to a second position wherein the lever is moved out of engagement with the bolt arm upon actuation of a tripcord operable by the occupant in the boat.
