Re: Opinions on PDF, Harness, & Tethers?
I once read an article in British magazine about testing safety harnesses. The ran a boat at 4 knots, and had a guy in a safety harness jump overboard. With the tether attached at the centre of his chest , his motion thru the water built up such a huge bow wave, that he couldn't get his head above it, and it threatened to drown him. A few years ago, a guy was drowned that way, by his "Safety Harness" in the Farallones race. Before they could get the boat stopped, he was dead. I'm surprised no one filed a lawsuit against the company which made the "Safety Harness"
Then they tried attaching the tether to the back. Worked well, he was comfortable and could breath, but there was no way he could reach the tether to pull himself in.
Then they attached it to the top of the shoulder. Much better! He could breath, and he could pull himself in.
Another advantage of the top of the shoulder attachement point is it doesn't dig into you when you wear it in your bunk. I use a lashing in front, instead of metal parts , for the same reason.I build mine that way, and wouldn't consider doing it any other way.
