Okay before this goes off on a tanget that was not intended, my response to Rolf was created with the assumption that teams would be pulling off their spin kit during the regatta which was CLEARLY NOT what he was saying (my bad).
The events where this could be an issue it is handled by the NOR and SI's. It's all good.
If you enter an event as an "F16" or "F18" or "Tornado" or Hobie 16, if your boat starts the regatta conforming to the class rules under which you entered and then mid regatta you change something that takes the boat out-of-class, you should get protested and DSQ.
Class rules simply define what boats of common name "look" like.
