So what's the trick with the main halyard lock? If I tie the halyard to the ring I can get the sail up but not down. If I tie the halyard to the shackle I can get the halyard down but not up. There must be a trick.
If you tie the knot to the top of the ring, I believe it's more efficient. Once it's tied, move the not to the side (depending on which side of the hook the halyard is on up top) so it will hook in without the knot getting in the way. Face the knot away from the hook too.
