The current NHC and IRC numbers are shown below. If you need help applying for an IRC number then please speak to someone on the Race Committee, see the Sailing Handbook elsewhere on these pages.
Whilst boats can apply for a revised IRC number a yacht will not have her rating within the club changed midway through a series. It is therefore possible that a yacht may have two different ratings when different series are run concurrently.
NHC numbers are the Base numbers and may change after each race according to the particular rules. IRC numbers shown below are currently valid for the Spring 2020 series onwards.
