Self-steering without a windvane - Jester Challenge

Scallywag II self steering on different points of sail during the Jester Atlantic Challenge 2014. More details about how to set up for reliability in differing wind speeds are given my self-steering Emu videos from the 2018 Challenge. John Letcher's excellent "Self-Steering for sailing craft can be downloaded for free at https://jesterchallenge.wordpress.com/articles/self-steering/ These and many other methods are described in detail.
