> I rarely go to Harrison's now but when I do I still use a waist belay to toprope people, and tie on with a bowline round the waist when I climb. This is all absolutely safe if done correctly with a locking twist round the hand with the inactive rope. I learnt as an alternative to school sports with Kent County Council in the late 60's. We used polypropylene hawser laid ropes which could also be hired out by anyone from the shop in Groombridge.
> For years I only used waist belays (with nylon rope) and, like others of my generation, held many leader falls and countless seconds. It is almost essential to wear grippy gloves when belaying a leader to avoid rope burns and/or letting go of the rope. It is still a very fast way to take in or pay out the rope and allows for a very dynamic belay if needed. Times have moved on and of course I now use a belay device when not toproping.
> Incidentally the guy in the image is not using a waist belay, you can see the inactive rope coming down below his hands. He might just hold a falling toproped climber, but he wouldn't be belaying me.
I have had exactly the same experiences as you, as will most climbers of our age.
And you echo my thoughts about the photograph precisely, that guy is not using a body belay, or a waist belay, he is holding the rope with one hand.
