If conditions are boisterous ,then just drop main and secure all with a single
line around main near mast
to keep mess from blowing about .Make a quick retreat o cockpit
to attend to your next preparations.(see Zee and others as above).
I use the technique Roverhi suggests most often ,with or without crew and with a reliable engine
But in most conditions once boat is head to wind with just the main up,I harden the main sheet enough that boom will not swing about too much if and when I need it for support while furling
sail. It is important to leave some slack in main sheet however to buy some time if winds are shifty or boat falls off too quickly thereby allowing main to fill with resultant difficulty in dropping. Now nip forward to front of mast
with back to bow , left hand removes halyard and coil is dropped near left foot and halyard is in left hand ( or secured under left armpit(!) with both arms embracing mast ( very secure).
OK now lift
left foot and pull luff to alternating sides as sail comes down, use foot to control decent by stomping on coil if sail drops too quickly to flake evenly.
I have bungees permanently secured along boom so all I need do reach under and grab and secure them as I make my retreat to the cockpit while tugging the leach aft and throwing the rest of the flaked sail on the boom. Takes less time than for me to type this.
It helps to have some way on so that the boat stays in irons as long as possible and of course the jib is already stowed.
Regarding the use of the armpit, best to be wearing a shirt and to let off some tension off the halyard before securing under the arm. I once tried this technique with a spinnaker
halyard when alone and almost set my armpit on fire.
