Oh, I hadn’t thought about the cleat sometimes being on the wrong side. I sail single handed as well, my thinking is that sometimes I like to let out a little extra halyard and prefer it being pulled up instead of letting the spin hang down on the spin pole. This I use in light air and flattening it as much as possible so I can ‘reach’ a little higher. The other idea is that in strong wind the boat wants to nose dive and I think if I could have the sail pulled up high on the mast and let the bottom part (tack I think) run out significantly I think the sail might lift the bows up and let me push it harder.
