Has anyone ever experienced dangling from a tether/harness OUT of the water for any length of time? I did...I''d go for my chances in the water on a tether rather than out if I was hanging from the tether on the windward side. Here''s why...
While at an offshore sailing school program, we were covering rescue & COB techniques. One thing that came out was how to recover the COB, particular if it''s a large COB (like me, around 275#) and a small crew on board (like my wife, @ about 110#). So, since my wife was along for the course too we decided to give it a try with us as a real world example to see how it would work and how it could be done.
The basic technique was to use the mainsheet tackle & the boom as a crane to hoist the COB (me) out of the water. So we disconnected the main sheet attached it to my
harness, and my wife started cranking away at the mainsheet.
The good news - she got me pretty high out of the water, and it''s clear should could have even gotten me up to deck out of the water under the lifelines.
The bad news - it was one of the more painful things I have had done to me. My back hurt for days. While it was happening it was painful, I could definitely feel every stress and strain applied by the
harness. Wouldn''t bother me if I was unconscious I suppose, and it beats the alternative. I was only lifted about 2/3 out of the water, and hung suspended for a total of less than five minutes. Of course this effect on me could be related to my size and physical condition to.
But we were at
anchor in a little lagoon in flat water. If the boat were pitching in eight foot swells, I don''t doubt for a second that if I were hanging overboard by my
harness without the water supporting me I would very quickly be shaken senseless. Also very quickly someone would experience pulled muscles and some very potentially dangerous and debilitating back injuries. Never mind getting beaten against the hull.
From my reading it''s been said that you should avoid allowing jackline/tether combinations to go far enough to take you behind the boat. I''m not sure if that applies to boats with swim platforms that are reachable or not. I''m still a little fuzzy on how to set them up optimally. Since I do only coastal cruising right now I see the optimal jackline setup as nicely rolled in the bag while I''m not out sailing in situations that require jacklines.
There was a report on jacklines &
harnesses release a couple of years back - can''t remember the body that did it. One thing that stood out was some discussion of the forces applied to a tether/harness/jackline combination by a falling body when it hit the end of the
line. I don''t remember the numbers, but the force applied was surprising. It was a very good case for shorter
lines, clipping to the windward jackline, and ensuring from that
line you can''t fall past the lifelines on the leeward side.
