when one of my uphaul ropes gave out, i purchased an EZ-uphaul
i use it with my 10-oh race sail that has a wide luff
if the luff fills with water it is almost impossible to pull out of the water
i hook the loop on my harness and slowly raise the sail so the water runs out
once semi out of the water, i can pull on the sail with my hands and the loop removes itself from my buckle
i still need to do some minor adjustments, butt it saved me today in zero degree weather

too cold and too tired to uphaul
it cost me just a little more than the regular uphaul and it has saved my back at least twice
that for me means it was a worthwhile investment !!!
