No, Mousetrap wasn't doing anything unusual on Sunday at the NA's when it was extremely light. I didn't do the tune, but I believe the skipper loosened things up, probably to about 38 or so. We struggled, but I think it was picking the wrong side and missing a couple big shifts. Speed wise we were fine compared to boats around such as eventual winner Sea Biscuit. The were just smarter. As to the 'radical' rig tension, you'll have to talk to the North guys. As I understand it, in light air they are use very loose lowers to allow the middle of the sail to fall off to leeward.
