Hi, i have some spare 8mm floating rescue rope for caneoing (the standard 8mm yellow floating rope) and was wondering if it would be suitable for hanging a hammock, i have been unable to find the breaking strain of the 8mm and wether it is likely to stretch at all, it is polypropylene i believe, it's nice and light too if suitable, i was thinking of attaching by threading through crab on hammock and tying either a blake's hitch or adjustable cawley hitch for quick and easy adjustment of hammock's position without having to untie/re-tie knots (just slide it like a guyline), i will give it a go to see if knots hold without slipping (i'm only 10 stone) but was wondering if anyone knows the suitabilty of the canoe rope regarding strength/stretching. Thanks.
