<p><strong>Historical Portsmouth Number List </strong></p><p>The RYA Portsmouth Yardstick Scheme is provided to enable clubs to allow boats of different classes to race against each other fairly. The RYA actively encourages clubs to adjust handicaps where classes are either under or over performing compared to the number being used. The Portsmouth Yardstick list combines the Portsmouth numbers with class configuration and the total number of races returned to the RYA in the annual return. This additional data has been provided to help clubs achieve the stated aims of the Portsmouth Yardstick system and make adjustments to Portsmouth Numbers where necessary. Clubs using the PN list should be aware that the list is based on the average performance of each boat across a variety of clubs and locations. The numbers in the PN list may not reflect the peak performance of each boat. </p><p>Historical numbers are listed below and have been collated from the RYA's archive of PN lists. It should be remembered that the Portsmouth Yardstick number list has been through a number of changes and the numbers listed below have had conversion factors applied where needed. It should also be remembered that whilst all efforts are taken for PN's not to drift, relative performance of older boats may be quite different to modern classes. The numbers are given as a starting point to help clubs arrive at a fair number and if these numbers are used then they should be reviewed regularly. </p><p>Users of the PY scheme are reminded that all Portsmouth Numbers published by the RYA should be regarded as a guide only. The RYA list is not definitive and clubs should adjust where necessary.
