Hi Linda, my idea may not be the best, but I made jack lines for our boat several years ago anticipating some off shore cruising; have yet to use them. Purchased bulk flat one inch nylon cargo strapping from our local industrial supply house (good for several thousand pounds working load) and made a bow cleat loop on one end of each. Straps, port and starboard, are long enough to reach and secure to a stern cleat. Also have the tether and harness. Maybe some day.
