Bearing away means steering through the wind, this is, leeward, holding the board away from the wind. It is done by tilting the centre of the sail forwards –tilting the rig towards the nose with the front hand while tightening the sail with the back hand– to reach the desired course, for example, changing from close hauled to beam reach, or from beam reach to broad reach.
Rising the clew will make the board bear away, getting further away from the wind.
