Hey guys!
If you can tie a clove hitch, you can tie a quick release clove hitch. All you need to do to tie it is to not bring the bitter end all the way through. Just leave a loop or a bight in it.
When you want to untie the hitch, just pull on the bitter end and it will spill the hitch.
You guys must do the same thing when you reef your Mainsail. You gather the bunting of your mainsail and tie a series slipped reef knots to hold it in place, right? A slipped reef knot is nothing more than a square knot with a loop or bight left in it.
You can make a slipped knot out of a half hitch, clove hitch, or a square knot by leaving a bight in it.

This hitch is so easy that you can do it with the thumb and fingers of one hand. It only takes one hand to spill it. You can slide the hitch on the lifeline without having to untie it.
To tie this hitch, just throw the fender line over the lifeline and come up on the right side of the standing part and bring it back up and over the lifeline to the left of the first turn and finish it off by leaving a loop instead of bringing the bitter end all the way through.
The last picture shows my sail stop which is nothing but a short line wrapped around the mast and over my mast winch, with a slipped reef knot tied in it. The line is secured to my mast winch bracket with a thin twine. This is what keeps my sail slides from falling out of the mast track.
