Spinnaker / White Sail ratings in IRC, YTC and LAH

IRC and YTC ratings offer both "spinnaker" and "white sail" options. Competitors must choose one for each series in advance, as changes are not allowed mid-series.By default, the Race Management team applies the "spinnaker" handicap. To use the "white sail" rating, competitors must formally request it at least 7 days before the series begins.Competitors can select different ratings for the TEK Early or Late Series and the Spring Series. However, opting for the "white sail" rating may result in a lower IRC or YTC class.

LAH Handicap

‍
The LAH handicap system operates on performance, analyzing each boat and the entire fleet in LAH1 or LAH3 classes after each Thursday race. It adjusts each boat's handicap based on its performance relative to the fleet.The club uses "Sailwave" software, a long-standing tool also recognized by the RYA and widely used in sailing clubs. Sailwave offers adjustable settings to tailor results, which the club uses to account for strong tides and other local factors. To demystify this performance-based system, a document has been prepared explaining these settings in simple terms.
