What Labatt says is quite correct and does work well, but if the wind is light and flukey you will still have an uncomfortable night. Theis is because some times the yacht will lie to the wind and other times to the swell or current. You need a steady wind 5 kts or more from same direction.
I actually use my boom preventer line to act as this long snubber. It has a snap shackle like a spinnaker sheet and is quick and easy to rig to the hook on the snubber.
By leading this line to a cockpit winch (via a turning block or mid ships cleat) I have full control of the angle from the cockpit. Each boat will sit differently.
If you are really straining to pull the gear in as it is too short, extend the snubber using a double sheet bend and a length of mooring warp. It is taking only a low amount of strain. If I am ever worried about knot this slipping, I use a tiewrap (zip tie) to seize the tail to the standing part.
