National Handicap for Cruisers – NHC is a progressive handicap system with the specification provided by the RYA. A list of base handicaps is available for download from the RYA site. After each race Sailwave adjusts the handicaps based on the rules of the NHC specification. Sailwave supports dual scoring with only the inputting a single set of results, so that results could be scored as a fix handicap such as IRC and progressive handicap NHC. The intention is to encourage sailors by making the competition closer.
To use the NHC rating system select it from Scoring system – Rating system and typically select the internal calculation mode.
If you have Excel installed then you can select the External mode and Sailwave will use Excel to perform the calculations allowing you to see how the calculations are performed and verify – If you want to get a bit more advanced and are familiar with Excel you can even modify the template so that you can perform virtually any custom handicap system.
The NHC calculations for 2014 have been revised and use simplified. The Sailwave version with support for the new 2014 algorithms is now available in Beta via the Sailwave User Group and will be released here very shortly. Version 2.9.7 installer here has the NHC 2013 algorithms although it can support NHC 2014 with a new SWHelper file and Template available at the Sailwave User Group.
