I must be honest, Ive never tried a shorter rope and I dont have any "triangle"?
This ring just travels down the anchor line until its immediately above the anchor, then it lifts the anchor and I carry on running until we feel the chain travel through the ring. Once the chain has gone through the ring, its someone elses job to handball it back in 😉
I like the length of line because we can drop the anchor into the water with the buoy on the deck, then just chuck the buoy in once the anchor is on the seabed. I can reverse a bit to get it to the right side of the boat for retrieval.
Ill have to look at others set ups next time i see anyone.
