That was my first summer sailing a new boat, Lian. Converted her to Chinese junk rig and used a second-hand prototype sail made of regular white tarp for testing it out. The plan is to sew a new sail for the next summer. So far so good!
On that video, we are out at Tallinn bay testing the self-steering wind vane that was installed on the very same morning. It happened to be a rather windy day with gusts over 15m/s, but we both were excited to see the result. From the very first moment, she worked superfine on every course we took!
That particular wind vane is one of the early prototypes and it has been continuously improved over time. Go check it out: windyselfsteering.com
