J/30 Class Association Forums J/30 Forum One Design Class Rules Proposed change in class rules for mainsail cloth materials

Russ,

The weight is based on a sampling of class legal mainsails that were weighed from multiple sailimakers, with the lightest recorded at 30.5 pounds and heaviest at 36 pounds. This provides some margin of error.

The phase in date is intended to allow those who have recently purchased mains to make sure they do not feel obligated to go out and buy a new mainsail.
