Single Line Reefing System

Fall weather often brings stronger breezes.  Reefing the mainsail keeps the balance between main and jib and is easy if you have a single line reefing system.
Here's my setup for single line reefing.  I've got this rigged on Snickerdoodle for both my first and second reef points; and, can easily tuck in a reef in less than a minute.
I have used a swivel block - secured near the base of the mast - for my cleat.  It is easy to use from any angle in the cockpit.  You could also rig this setup with a traditional cleat near the aft edge of the cabin top.
Reefing is easy - 1 Tighten the Topping Lift (not shown) and sheet out the main; 2 Release the Boom Vang (also not shown); 3 Lower the main halyard while pulling in on the reefing line.  As the main is lowered, the reef is automatically tucked in; 4 Ease the Topping Lift; 5 Sheet in and set the Boom Vang.  You are now reefed.  I don't tie up the middle reef points unless I plan on being reefed for the rest of the day as around here the strong winds often blow themselves out in an hour or so. 
Shaking out the reef is just as easy... simply reverse the procedure above.
Practice this on a light wind day so that you get used to each step.
