After dumping my SuperCat 17 which had no dolphin striker and a big rise to the front beam I needed a way to drag my old fat body aboard when exhausted. I threw the righting line over the bridle where it meets the hull, then tied it off to the mast. The lines hung down as a "hammock" which I could step on while holding on between the the hull and beam. Very successful since my weight was centered over the line.

Now I keep a loop tied in the line by the mast and a carabiner at the right place out the line so I can clip this rig together quickly while swimming. Works great if exhausted.
