Welcome to the South West YTC System

The South West Yacht Time Correction System (abbreviated to YTC) has been developed over recent years to assist the wide variety of yacht-types within a club or port, and these are mainly cruiser-racers, to race competitively and fairly. It is based on the statistical models developed by Professor Linda Wolstenholme, of the Cass Business School and Emsworth Slipper SC.

The ethos throughout the process is to develop a boat's number in a fair, open and transparent manner, if necessary bringing the yacht's skipper into the discussion where appropriate. The system also aims to provide a mechanism whereby skippers of any skill level may feel encouraged to race their boats at all levels of racing and in all fleet racing formats. Overall, it is intended that the YTC process will assist the achievement of fair racing as required by the Racing Rules of Sailing.

The system has always been examined at the end of each racing season with a view to making improvements, and feedback from skippers and yacht-owners is a fundamental part of this process. During the winter of 2017/18 a number of improvements to the system have been introduced as a direct result of feedback received, including:

  • Web-based entry and sail measurement forms
  • In-house sail measurement
  • Each competitor will receive a YTC certificate, showing the YTC number for the season and the yacht and sail measurement data on which the number is based
  • Spinnaker sail areas and hull overhangs are included in the derivation of the YTC number

The YTC team hopes that all users of the system have an enjoyable and rewarding racing season.
