Shorten Course for Race 13 CW

At 1500hrs BST all yachts that have not finished must  record their GPS position at that time and supply it to the Race Committee.

This will be used to calculate the distance made good along the rhumb-line. Should a yacht not be exactly on the rhumb-line at 1500, the rhumb-line distance will be established by taking a line from the yacht’s position to the rhumb-line and at right angles to the rhumb-line.

The yacht’s distance made good along the rhumb-line will be divided by the elapsed time of the race to give the Actual Average Speed.

For a yacht not finishing by 15000 hrs, the rhumb-line distance from the start to the finish will be divided by the yacht's elapsed time for the entire course to give the Actual Average Speed.

The Actual Average Speed, however derived, will be divided by the yacht’s IRC number to give the Corrected Average Speed.
