what sis a blind landing and how to do one?

Land back facing the boat.I do hs blind 180's by letting go of my rear hand rotating blind, and pulling the handle to my hip.

Yeah to learn how to land blind go to a ollie 180 just when ollie let go of ur front hand and turn at ur hips and get the rope behind ur back

A blind 180 is a backside 180, opposite rotation from frontside. Landing blind refers to not passing the handle until you have landed.
