A Brit showed me the simplest topping lift.
I have a shackle on one end of the topping lift that always remains connected to the aft end of the boom. Once the main is raised, I take a boat
hook and hook the topping lift walking the standing part forward where I hook it on one of the reefing hooks. Once the standing part is hooked, I just tie off the bitter end on a cleat. No chafing of the sail, no leaning over the side to unhook the topping lift, no bungee cords involved.
Very neat and seaman-like.
