In a RIT Class I was taught how to make a 3:1 mechanical advantage system using three extra large carabiners and my personal escape rope. You have a figure 8 with one carabiner to the victim, and a few feet behind the figure 8, away from the victime, a butterfly is made. The rope works its way up to an anchor with the second carabiner. The rope runs through this second carabiner, your anchor, and then the ropre runs through the third carabiner attached to the butterfly. I'll try and get a picture for better feedback and explanation. However, I now carry 50 feet of 8mm Kevlar rope for this RIT scenario. I have seen some great 3:1s out there but this might be my only option. For now, I think about wet gloves and the thin diameter of the rope and how this will easily slip out of my gloves. Do I go a tad thicker on the rope and if so, what kind? Shorten the length by 10 feet to fit in my coat pocket and add some knots to prevent slippage? This is what I have to work with. Looking for ideas with what I have. Fire Engineering has a nice articles and video. But this is what I have to work with. Thanks.
