How many hand spans to the center of the rope?
Memorize how many hand spans it takes you to flake a rope.
For a person about 5’10” tall, it’s about 30 full hand spans for a 50 meter rope, and 36 spans for a 60 meter rope.
It’s a useful number to know. Why?
Half of this number (15 spans for a 50 meter, 18 spans for a 60 meter) gets you to the middle of the rope when setting up a rappel, and you don’t need a middle mark on the rope.
If you are prone to forget arcane numbers like this, write it in pen on the inside of your helmet.
