Can’t speak for the confined space rescuers, but the climbers switched from the bowline to the figure eight, mainly, because the bowline CAN untie by itself under certain situations.
Generally, the bowline is frowned upon in the life safety situations. However, when I was learning to climb (a very long time ago), I was told that the bowline requires a second knot ( a hitch) after it. It was there to prevent it from unraveling.

I'm not sure exactly what a double fish knot is compared to any of the other knots. Interestingly I was always taught that climers and confined space rescuer use a figue eight (reweave or on a bite) instead of a bowline because of its retained strength. It's a interesting read at least. http://caves.org/section/vertical/nh/50/knotrope-hold.html<https://eur01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fcaves.org%2Fsection%2Fvertical%2Fnh%2F50%2Fknotrope-hold.html&data=02%7C01%7C%7Ce36fa7d22f1542bbcc8908d569f1dcfa%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636531409872933113&sdata=CUchrX9XL9Kgs7Mi7kc3hEGJHAsZoSE4MVfcx7dCT30%3D&reserved=0> Josh On Thu, Feb 1, 2018, 10:49 PM Rick Brass via CnC-List <firstname.lastname@example.org> wrote: I couldn’t help but chuckle because I’ve been tying the Halyard Hitch, Jeanneau Variant since I was about 12.. Except what I’ve always used it for is to tie the monofilament leader onto a fly when fly casting. The knot (bend actually) that I learned takes two passes through the eye of the hook and then is tied like the Jeanneau bend. And when I learned it from my Grandfather it was called a fisherman’s bend. And, BTW, one of the reasons the bowline is the most basic knot taught in the US Power Squadron and CG Auxilliary basic seamanship classes is – according to the course material – that it retains around 90% of the strength of the line you are using and is the highest among the common knots and bends.

It's just the halyard hitch with a different finish. So perhaps it should be called halyard hitch, Jeanneau variant? _______________________________________________ Thanks everyone for supporting this list with your contributions.
