Look fellas, making **** up as you go along is not clever. It appears that the GC is attempting to make the class ISAF. if that's what you guys want then you have to follow thier rules not to mention the rules of the class.
If you rock up to a measurement protest, you WILL need a measurement certificate. If the boat doesn't have a measurement certificate then it DOES NOT MEASURE. Even if the boat is within the rules. Full stop no more arguments. Your personal opinions are of little to no value.
