I wouldn't of thought so, wouldn't it just be part of the class registration fee. Admittedly I haven't much experience with the measurement process, was very young when doing previous boats, but it would seem a bit rich for a class measurer to charge for their services, it is a volunteer position afterall...isn't it? Maybe I've got it all wrong.

There was no charge to measure and stamp new sails at the last nationals I participated in.
