Just got on the plane, got the boat level and a big gust coming through. Guess it's not the moment for the windward shroud to give way! Just as well it went on the lake as a week later we were sailing in Swanage with gusts up to 30+ knots in a biggish sea. Don't want to think what might have happened if it had gone then. Problem was tired dyneema, so that is lack of checks and owner to be blamed, Very unusual as I am generally very fussy about my boat.
