I never hooked it up but i have a system built into my astral lift jacket that was intended for towing kayaks. It's a strap around e vest with a ring and a quick release buckle. E ring has a piece of small line tied to it which is then coiled into a small pouch on the side of the jacket that is held closed with a zipper. I kept a carbiner on the end of that line for clipping unti the boat or tossing the line. Ideally, if clipped in and separated, the line would uncoil from the pouch until taught and i could still get free by pulling a quick release ball in the jacket.
