Notes on certification of yachts. General definitions – closed rules/open rules. Certification control, Official measurers, personnel definitions. Boat definitions, Hull definitions and measurement, Hull appendage definitions and measurement, Rig and sail definitions and measurement.

 

World Sailing – Measurers Manual 2017

Don’t read it all but certainly use it as a reference, some good background reading on accuracy and repeatability and also a lot about weighing. Did you know an IOM calibrated weight in Southampton will weigh 8 grams more at the North Pole with the same scales!
