There 's a very interesting new design of life jacket from Team O in GB that keeps a victim who has fallen overboard with head above water and dragging backward. It also facilitates retrieval to the boat. Looks really good. The PBO test video is worth watching.

Good point, David! First rule of sailing: STAY ON THE BOAT!

But I do believe that having the tether out of the way behind you makes sense.

By the way, I finally discovered what Tystie means while visiting Rum in the Small Isles of Scotland! Thought of you!
