make certain bottom and rudder
are perfectly clean and sails are in good order
observe local weather
patterns and weather
wait until wind and tide are going where you want to go
pull up anchor
use combination of pressure of wind on sails and water on rudder to turn boat and move it in desired direction (have this part figured out before you raise anchor)
sail out of anchorage without hitting other boats, running aground, or fouling anchor lines.
(or do it at night when no one's around;-)
upon arrival at new location, chose desired anchor point
turn boat into wind and release sheets
when boat stops moving forward (preferably over desired anchor point) lower anchor
as boat drifts backwards set anchor and adjust as desired
Complete in stages if necessary depending on wind and tide
you may need one wind or tide to get out of where you are, and a different wind or tide to get into where you want to be
or go rent a runabout for a day and tow it. Then go tubing.
