Topping lift
I use the whisker pole ring also, which avoid adding more hardware, but have a pennant made up to size with a stainless carbiner on the bottom. So when the sail is raised and lifts the boom, it is easy to unsnap and simply hook the bottom onto the ring where it stays out of the way. It is essentially the saame as Richard's, from his picture, except for the carbiner and it is made of rigging wire.
