Handicaps for the 2019 Season
The Table below shows the Portsmouth Yardstick Numbers (PYNs) your Sailing Team has decided to use at the start of the 2019 racing season.
Setting handicaps for racing between different designs is not easy and we have followed the best practice recommended to clubs by RYA. This means we start by looking at the RYA's published list of PYNs noting they are based on results submitted from clubs across the country, including many whose conditions are dissimilar to those in Chichester Harbour and do not cover all our classes. As recommended by the RYA, we have therefore adjusted these published national PYNs to take account of local conditions and looked elsewhere for classes not included. We do this using the RYA's own tool to evaluate the data returned from 7 Chichester Harbour Clubs over the past 9 seasons and also checking to see if there have been significant shifts when looking at just the last 3 seasons. In addition we have taken into account the "WWSC data only" results where these appear to show a class of boat is performing differently in our racing to those reported at other clubs.
In the Table below we first show the PYN used for each class in the 3 previous seasons' racing at WWSC. Then there are 2 columns which show PYNs computed from the Chichester Harbour and WWSC-only results from between 2016 and 2018. The next 2 columns show the RYA national PYN both for 2018 and 2019. Finally we give the Committee's agreed WWSC PYNs for use in 2019 (in Green) with a brief comment on its basis. Where the computed PYN from local data is based on only very few results (and often just 1 boat), we have placed more weight on the national data.
The Committee intends to review the racing results for the first half of the season and make changes to PY numbers, if warranted, prior to the start of Regatta Week, which will then be valid for the rest of the season.
This year we will again experiment with applying "personal handicaps" if only to add an additional element of interest to our Racing Series. (Personal handicaps are based on the results achieved by a particular helm + boat combination in previous WWSC races.) They will not replace the normal Class-based PYNs but will be used in parallel with them and reveal how a boat's performance changes from race to race.
