Calling puffs downwind is important because you have more flexibility to sail high or low to meet approaching puffs. When calling puffs downwind, ask yourself the same questions as you would sailing upwind: (Lift or header? How much wind? How long will it last? When will it hit?). In this case, the crew just off the trimmer's hip might say:"Here comes a leftie. It's a fanning puff with lots more breeze. Head up five [degrees] to get to the header. Puff on in 3¿2¿1."
