I agree with Swimstar.
Share the love.....or info with fellow paddlers.
I can see how this might work.
If a trapped boater (pinned in a kayak, foot entrapped, etc.) jettisons their bag, the floating line and bag deploy downstream up to 65 feet. The Reach Device stays attached to the victim's strong swimmer's belt, (and those on shore or in another boat throw their Reach Device across the floating line. The Reach Device clips the line, captures it, and the rescuer has a secure line to the victim with which to quickly assist their escape.
