Many coming to our sport are unsure of the how the winners of Sailing Races are determined.
A. The First Boat to cross the Finish Line in any Sailing race is described at the the Line Honours Winner .
If all the boats in the race are identical, this is a fair result, but many races comprise boats of different sizes and capabilities.
Various methods have been developed to provide all boats in the fleet with the opportunity of winning a race, if they have been sailed well enough -- known as Handicapping, Yardsticking. or Rating.
All these methods use Timing and Calculation to determine the Race winner - if you sail well enough, you will win the race even if you crossed the line in last place!
B. Race Timing
The Timing of the Race commences when the Class Warning Flag is first raised. This is usually 5 minutes before the first start, but if multiple starts are being used, it may be 5, or 10, 15 .... or up to 30 minutes before a particular start. Race Officers make a note of this "waiting" period for each start, often labeled the "offset". Once the Timing has commenced, it runs until the the last boat has finished .Timing can be by a watch, or more often a Stop Watch.
The Time each boat finishes is carefully noted by the Finishing Team. This Time is known as the FINISH TIME and is used as the base to calculate the race results.
1. Firstly, the "Waiting period" or "Offset" is subtracted from the Finish Time to work out the ELAPSED TIME - the actual time that each boat took from their Starting Signal to crossing the Finishing Line.
2. Once each boat has has an Elapsed Time for the race, that time is adjusted by a Handicap known as a Yardstick or Rating that modifies the Time according to the different performance of that boat. In Australia, Dinghies and Catamarans use a Yardstick first developed by the Victorian Yachting Association and now adopted nationally by Australian Sailing and known as the Australian Sailing Yardstick (ASY).
To work out this Yardstick, hundreds of race results were analysed to determine the relative performance of most common boats raced in Australia, and the Yardsticks are checked and adjusted annually against new figures supplied by Clubs and Class Associations. Comparisons are also made with other Rating systems, notably the British RYA Portsmouth Numbers.
3. This adjusted Time is known as the "CORRECTED TIME" - a time corrected for the different performance of different boats and allows boats of different design and performance to compete fairly against each other.
For example a Tasar with a Yardstick of 108 (108%) can compete against a Laser Radial with a Yardstick of 118.5, Sabre with 127, a Sabot with 160.5 and an Optimist with 170. In this way, a Optimist could win a race against a much faster Tasar, if sailed well enough.
(Elapsed Time / Yardstick) * 100 = CORRECTED TIME
Line Honour TASAR --- ( 45.65min / 108 ) * 100 = 42.27min ----- Corrected Time (SECOND)
OPTIMIST--- ( 71.32min / 170 ) * 100 = 41.95min ----- Corrected Time (FIRST)
4. The days of calculating post race with pen and paper, even with a calculator, are long past, and now specific Race Scoring software based on computer spreadsheets is used to calculate Results.
5. Maroochy Sailing Club uses the Sailwave Scoring program and from an input of the Finishing Time, and the Race Offset, the program calculates the Corrected Time of each boat and ranks them in that Finish Order. Errors occasional occur, but are most likely from mis-recorded Finish Times or fnput errors from rushed or jaded Scorers. Once identified, errors are easily corrected and the scores re-alculated. The Scoring Programs also track performance over a Series of Races at a Regatta, discard the worst performaces and calculate the Series Results.
