loose leech?

[shorebird]

The sail is all the way up, the luff is well tensioned, as is the outhaul, and, without the cockpit enclosure, the leech would be fine. I'm confident its just that the enclosure was added without proper consideration for proper sail trim. If I wish, I can easily remove the offending bit of enclosure and tighten up the sail for a bit better performance to windward. Thanks again for all the replies.
