How do Rules 85 and 86 apply to the question posted by Ding?

Looking at the Regulations, they don't use the term International Class anymore, but the intent is covered under World Sailing Classes.

I read Reg 10.5 (f) slightly differently than Matt. I would say that the class is still responsible for approving the SI change per RRS 87; however, the class must first get approval of World Sailing, and that is only required for a class event (defined as initiated and controlled by the class association).

Anyone still awake?
