Ratings & Measurement

Ratings & Measurement

Rating systems, handicaps and yardsticks, and class certification are what define a boat's equipment and how it is scored in a race. 

Classes are defined by measurement rules. Handicapping allows boats to compete across classes and allows boats and crews to compete based on performance and equipment on an equal basis.

Systems such as IRC, ORC International and ORC Club are independent data based ratings of a boat's performance potential and provide events scoring options that are scientific and unbiased. Superior to performance handicapping, clubs with keelboat fleets are encouraged to take advantage of these services.

To enquire about ratings, please email ratings@sailing.org.au (prefered) or phone 02 9170 6917. Please note business hours for the Rating Office are 9:00 to 16:30 Monday to Friday except Wednesday where the times are 9:00 to 12:00.

What is ‘Aft Rigging’?

Aft rigging on a racing yacht, the stays at the back of the bus, controls mast bend and forestay tension to optimise sail shape for speed. So, it matters how it is rated.
