mary, et. al.,
Sorry I didn't explian myself. There were earlier posts on this, and others felt this way as well.
The situation is much like Keith has described in his post.
With my sit harness, I can easily get out of it, if I can't get the trap hook undone(the reason of a whole thread about an attachment system), and I'm being pulled under from rigging, or a turtling boat, kinda like the Tornado sailors death last year, he was wearing a full harness.
And another thing, I kinda of enjoy allowing my Abs to do some of the work. People are too portly these days.-flame suit on!
