Just to confirm Alistair's post on how to rip a Halcyon OPH in two. The failure was at the the lower left hand diagonal slot in the backplate where the backplate cut a neat diagonal slice across the webbing. The situation was that the diver (me) was balanced on the gunwale of the dive boat Elena-C and about to make a backward entry when my KT reel caught on the gunwale lip as I launched myself into the ogin. The KT was attached to the left hand hip D ring and remained on the deck with the D ring as the harness parted at the backplate. I estimate that the total weight of diver and equipment was around 135-140 Kg and the distance from the gunwale to he water around 1.5 to 2 metres so a considerable shock load on the webbing. Needless to say despite the damage to my gear I was glad that I didn't end up strung up like a chicken on the side of the boat. And the KT, well it just shrugged its shoulders and stared back at me completely undamaged
