i got a 50 ft. anchor rope at walmart. has a snap hook on the end. make a loop 4 ft. from the hook. tie a boat fender through the loop, attach the hook to the loop. if needed, throw the bumper, loop goes unde3r the arms of the swimmer. fit in a bucket, and should be the first bucket you put on the ice. if you ever use it, (hopefully you won't), it's worth the cost and if you don't it's there if you ever need it.
