To be able to advance, it is necessary to refer within the meaning of the wind (white arrows on the level of your b?teau) and clicker on the various degrees at your disposal in order to put the veils in a precise direction, to advance with your own way. Attention not to let to you distract, however, because a burst of speed too quickly acquired makes miss precision. Good luck?
