The rules for dinghies participating in the Friendship Series originate in the Notice of Race of the Copenhagen Vintage Yachting Games 2018. They are:
The International 12 will race with wooden clinker built according to the original design, and shaped, rigged and fitted accordingly. Vintage dinghies will generally be accepted, round wood should be solid, sails should be fixed to boom and lug such that no profitable in-race adjustment is possible. There should be no gear for profitable in-race adjustability of the mast foot. On individual cases the acting International 12 class authority shall decide with or without request.
