Headsail Twist in 3d

NauticEd’s FREE Sail Trim Course—including animations like this that make the concepts instantly visual - https://www.nauticed.org/sailing-courses/view/basic-sail-trim?utm_source=youtube&utm_medium=video&utm_campaign=T3dsLBa15XE In this animation, Grant Headifen (Global Director of Education for NauticEd) shows how a headsail twists out relative to the fairlead moving forward and back. You’ll see the fairlead aft with air spilling out at the top, then watch what happens as the fairlead moves forward: the jib sheet angle pulls down more on the leech, the leech tightens, twist comes out, and the airflow direction at the top of the sail changes. The foot loosens a little while the leech tightens—resulting in more wind power at the top. Conversely, moving the fairlead aft reduces power aloft and reduces the heeling of the boat. #sailing #sailboat #sailingschool #sailinglife
