To gain IRSA designation some straightforward, but important, standards have to be achieved. 

• The class has to have a certain number of boats across a certain number of continents and countries. 
• The class rules have to be written to a common standard, the WS Standard Class Rules (SCR) format.

These requirements would apply to any class which is not already an IRSA designated class e.g. RC Laser, DragonForce, DragonFlite, RG65, Micro Magic. Whereas the numerical requirements may be met in all or most of these cases (please see the IRSA Regulations for these), the requirement for WS SCR format class rules is not.
