I teach sailing to kids at a local club. You wanna see a cluster, try it with ten, overanxious 12 year olds, all at the same time. Obviously the wind direction can mess things up, but generally, if you point the bow into the wind (or in that direction) with dock
lines loosely wrapped fore and aft, then raise both sails (while still tied up) allowing them to luff. Then push the boom over it to catch the wind, when it fills, release the bow
line. Then ease the boom as the bow comes away from the dock. Sheet in the
jib on the leeward side. Let go the stern
line and sail away. Easy right? Practice makes perfect.
