Scooby,

It is in the Rules that an event measurer is compelled to notify the RC of any equipment violations and the RC is to protest the offending boats. There is a section of the Rules called "Event Measurement" that contains the following:

F.3.4. EVENT MEASURER’S RESPONSIBILITY: The RRS 78.3 gives the initial authority to the event measurers to determine whether an item of material complies or not with the class rules. This authority is afforded only during the event measurement. If a measurer is convinced without any doubt that an item of material does not comply with the rules, he shall write a report to the race committee, who shall lodge a protest against the yacht.
