With speed, unhook, get out of the straps, and rake the sail back toward the tail (oversheeting) so the board heads into the eye of the wind. Remember, safety first -- in all moves all the time! So verify your have room and will not collide with another sailor (pay close attention to an upwind sailor coming downwind in a ballistic jibe.). You will head upwind farther than you think and you will be blind to upwind traffic in the middle of this maneuver.
Move the forward foot to the front of the mast and shift the back foot slightly forward while your keep the sail racked back. Also, keep sheeting in the sail with your back hand to maintain power in the sail and board speed. Most people grab the mast below the boom with the front hand at this point -- I don't. Speed is your friend!
As the nose of the board (NoB) approaches the eye of the wind (EoW) then slide your front foot over the centerline and transfer your weight onto the front foot. This should be done while the board is planing. Give one last tug with the back hand and then release it and grab the boom head or the mast right below the boom. Release the front hand during the grab. Quickly!
Shift both feet to the front of the board, but as close to the mast as possible with your body balanced over the centerline of the board.
Pull the mast toward the nose of the board while simultaneously grabbing the boom on the other side of the sail and placing your new back foot between the foot straps. This feels like you are just stepping aside and letting the rig pass by you; instead of you stepping around and passing by the rig. This is where most people topple.
Sheet in and pull the boom up with the back hand while pushing the front hand forward (this is called the bow and arrow position) to present the other side of the sail to the wind and power up the sail for the new board direction.
Push on the front foot until the board is sufficiently pointing in the new direction. Trim, adjust feet and sail away you tack meister.
