Nacra Class Rules

Does anyone know where to find a copy of the current Nacra Class Rules? I'm in the process of putting together a Nacra 5.0. I will daysail and race it, primarily in events governed by the PHRF rules which require that boats conform to their respective class rules. I want to make certain everything on the boat is class legal, but I'm particularly concerned about the sails.

Are there specific lofts approved to make class legal Nacra sails and if so who are they? Do the sails come with the approved pedigree patch like the Hoble class legal sails?

Thanks in advance.
