In this position your back is to the wind and you are holding onto the mast with both hands with the sail flagging downwind.
 

Your front foot instep is against the mast foot and your back foot is behind the mast on the centerline.  Your feet are roughly a shoulder's length apart.
 

Arms  are extended and holding onto the mast about 6 to 8 inches below the boom.  Your knees are slightly bent.
 

The rig (sailing, boom and lines) is flagging downwind and a "V" is formed between the mast and your body.

Lower the rig and sail to get off the board or assume the rescue position.
 

Turn the board.
