"Crew shall nominate which mainsail size they will use before the regatta starts – small or standard. Crew may change their mainsail size for any one or more days during the regatta. They shall prior notify the Race Committee or Shore Team before changing not later than one hour before the first warning signal for the race affected by the change of rig. For races that a sailor uses a different size sail to that originally nominated, their point score will be increased by 10% of the fleet size, to a maximum of the fleet size+1. Grand Master and Legend sailors are exempt from the penalty and are not required to provide notification for a change of sail size. Failure of other sailors to notify the Race Committee or Shore Team may result in a DSQ from one or more races."
