Hi Aeronut, Sorry, my error, it was circ. not diameter. I understand that ‘circumferences’ are still how ropes are measured today. We were checking the current ratings for nylon ropes of the sizes stated and it is in the 30,000lb range, whereas the I calculated that the 200cwt would have been around 22,000lbs, I guess they have developed the nylon strands to a higher level. We are now searching through the Naval arm of the service for a suitable length of 4 1/4″ circ. piece of rope and hopefully someone to splice a terminal loop into it for us.(The original info we received from a vet. was the rope was 4 1/2″ diameter! The number was close except it was circ., not dia.)
Thanks for your help.
