Winter Series Race #2 Results
Last Sunday it was Race #2 of the Winter Series. A total of 10 yachts participated. We welcomed a new entrant Poppyseed from RMYC, a 26 foot Paul Whiting Quarter Tonner cruising design, helmed by Klaus Keck.
Newcomer Poppyseed was given the scratch start and she made the most of the early wind. Goldfinger must have been jealous! In fact Poppyseed was so fast that the yacht race coordinator was unable to shorten the race earlier as Poppyseed had already gone around the ‘S’ mark. Despite being the ‘slowboat’ for handicapping, Poppyseed had the fastest elapsed time!! The handicapper won’t be so generous next race!
The race was handicapped for a 135 minute ‘slowboat’ for a target finish time of 1:45pm. The mid-fleet yacht came in at 2:29pm, so it was a bit longer than expected, but unavoidable given the circumstances. At least it was a close finish for the majority of the fleet with less than three minutes separating 2nd and 8th place.
We raced the 7.6Nmi course #19 – Rp, T, S, Tp, Rp, S, although the race was shortened during the race to Rp, T, S due to a lack of wind. Sydney Harbour observations (Wedding Cake West) was 5-7kt, with gusts 6-11kt, mainly from WSW. It was lighter on Pittwater, especially around Towlers.
The next Winter Series race + BYO BBQ is on 31 July.
The approach taken to handicapping at Avalon Sailing Club is to handicap yachts based on personal performance (using elapsed times), rather than class based boat handicaps (using rig based measurements). Personal performance based handicaps have the benefit of encouraging participation, as race results are based on how well you sailed in a race compared to your ‘normal’ performance. This seems to fit in well with ASC’s motto of “Fostering, encouragement, promotion, teaching, and above all, enjoyment of sailing on the waters of Pittwater”.
For calculating handicap race results, for scratch starts, ASC uses the method of elapsed time multiplied by an Allocated Handicap (AHC) to calculate a ‘corrected time’. The yacht with the lowest ‘corrected time’ is the winner on handicap. For handicapped starts, the ‘offset’ times are calculated based on the AHC of each yacht and the expected elapsed time of the slowest yacht.
I think the preferred method of handicapping is to calculate the ratio of the elapsed time of each yacht in a race against each of its competitors and then compare that to the expected ratio based on assessed handicaps. Using this method, the full set of data is available to the handicapper for assessing a ‘normal’ handicap. This data can then be collated for each series, with the aim of the handicapper for the median performance of each yacht if she sailed ‘normally’ to be 0.0%. In an individual race, if a yacht has a negative median performance then she sailed faster than ‘normal’, and if she has a positive median performance then she sailed slower relative to ‘normal’. For determining handicaps, the use of medians, rather than averages, is a better method as it removes outliers from the calculation.
