Bear off the wind in control and with moderate speed in flat water or a smooth section of water like some rolling swell or Jibatorium.
Unhook and keep bearing off wind. Pull your backfoot out of the footstrap and place just in front of the backfootstrap.
Now pull the front foot out of the footstrap and step in front of the mast. This will be your pivot area to get around the mast.
This is where all the magic happens and the critical part of the maneuver. The feet will come together by quickly stepping the other foot to the mast and then shuffling around the mast so the feet are on the other side of the sail. This is kind of like dancing. The clew hand will reach to the mast so you can move the other hand to the leeward side of the sail and well. All this is performed almost simultaneously and quickly so you can get in the backwinded position.
Extend the front arm and backwind the sail with control. The sail is somewhat foward so the center of effort of the sail is exerting pressure on the nose of the board, keeping the integrity of your Jibe.
As the board approches ded down wind, start lifting the mast vertical and moving your center of gravity more toward the middle of the board.
Push the clew through the eye of the wind and step behind the mast to maintain your balance.
Reposition your feet and sail away.
