Sailing to the telltales means trimming your sails and steering the boat so that the telltales (small ribbons or yarn on the sail) fly smoothly, indicating efficient airflow. •On a close-hauled or upwind course, the telltales on both sides of the jib should stream straight back. •If the inside (windward) telltale lifts, you’re pointing too high—bear off slightly. •If the outside (leeward) telltale lifts, you’re sailing too low—head up a little. By watching the telltales and adjusting course or sail trim to keep them flowing smoothly, you ensure the sails are working efficiently and you’re sailing your best angle to the wind.
