Down force through the boom (into mast base) all the way through jibe, and especially in the set up for the jibe.
Look backwards when going into the carve,helps to get your hips,knees and shoulders into the same direction as the board
I found when learning(still learning) is to find a nice small wave or chop and jibe on the face of it this will help get your board turning with ease and then it's all a matter of flipping the sail, doing it this way it doesn't matter if your not properly setup with your feet hips etc once you get the feel jibing will become easier.
