I want to respond.
The strength and length of a rescue rope(s) one should carry is a personal choice.
When choosing rescue ropes a wise boater will consider the total of weight of the boat it is likly to be used on, the with of the river, how other boats in your group are set up with rescue gear.
I run small r2 rafts and 13-14 foot paddleboats on narrow steeper rivers......as such my 2,000+lbs 50 foot nrs pro waist rope does offer adquate stregth, and length for use in rescue and mechanical advantage systems... due to short length it is unlikly to be usefull in a 3:1 z drag....but it would work for a 4:1 pig rig,, however, given a choice I would I use my use my 5,000lb 75 foot NRS probag for a mechanical advantage setup.
If I was running full loaded oar rigs, on big rivers...I would likly carry a 150-200 foot higher strength rope...a 7- 10,000 lb rope I think would work....I would also carry larger pulleys to work with the larger diameter rope.
But this thread was about rescue ropes and gear that was carried ON YOUR BODY....there is no way that I know of to safely carry 150 feet of large diameter rope on your body while running class IV -IV rapids.....These ropes need to be secured in both yours and others in your groups boats.....so hopefully there is a rope that is NOT in the raft that is in trouble.
