Under what rules are sails certified for a 10R certified before 1st July 2016?

If a boat certified prior to 1st July 2016 has new sails, which rules apply for the certification of those sails?

Section C 8.1 (c) of the class rules tells us that for hulls and sails certified before 1st July 2016 the profile of each alternative sail shall fit within the profile of the sails recorded on the certificate. These class rules continue to apply to a hull and sails certified before 1st July 2016.

New sails fall under Section G 1.1 which tells us that sails shall comply with the class rules relating to the certificate, or with the 2016 class rules. For a hull certified before 1st July 2016 the previous class rules continue to apply.
