快速航⾏ To go faster off the wind you can set a big sail called a spinnaker. Conventional spinnakers are quite complicated to handle, but an asymmetric spinnaker is easier as it is simply a big reaching jib designed to catch bucket loads of wind! It’s used between a beam reach and a broad reach and decreases in power the further away from the wind you steer. The zone diagram shows you where to hoist, power up, depower and drop the sail in relation to the wind.
