Does anyone have photos of the anti-flutter lines on the leech of their Hyde gunter-rigged mainsail that they could post? Sailing into an F5 at Mylor, my mainsail started up an almighty thrumming and fluttering, which hasn’t happened in quite a while. I know that the leech can be tensioned by pulling down and cleating the lines that are sewn into it but it didn’t seem to work. Either I was doing it wrong or the business ends of the lines have defensively retracted into the interior, ninja-style, and need to be coaxed out again. All help gratefully received.
