The batten pockets in all sails made prior to 1/1/2012 shall lie at 90
degrees plus or minus 8 degrees to the leech.

Did you mean all sails made AFTER 1-1-2012?

[Geoff Sobering]

The batten pockets in all sails made prior to 1/1/2012 shall lie at 90
degrees plus or minus 8 degrees to the leech.

Did you mean all sails made AFTER 1-1-2012?

No. It's a "grandfather clause".
