Yeah, I wonder about bending it back, maybe building a fulcrum shaped to the extrusion profile. But I'm concerned the even with a pristine tube, this spreader/diamond arrangement is just barely sufficient, Although it is the current arrangement on ARC alum masts.

This main has the 1" alum tube as bottom batten/boom, no rotation inducer, and rotation is limited by moving the mainsheet forward on the clew plate in higher breeze. As the wind was light, the sheet was attached to the furthest aft hole, allowing full rotation. Main was in tight, and when we rehoisted we were well downwind, so the chute powered up slowly. We were sailing on stbd, and the mast bent off to port as one would expect. The spot it bent was just above the upper tang of the inner diamond, so if everything was working properly it should have been well supported. That's why we're so baffled.

Thanks Lost!
