The fleet of Corby 25s rated under the IRC handicap rule have just received a reduction of between 6 and 9 points, worth 22 to 32 seconds an hour, just in time for the ICRA Cruiser Nationals and WIORA Championships.
This significant reduction is due to an error discovered by the RORC Rating Office. Over the past few years owners had suspected that Corby 25s had too high a rating under IRC. Following requests for investigations involving RORC and the designer John Corby, it transpired that the keel bulb weight which has been sourced back to an IRC application submitted which was presumed to be designer data for the bulb weight was incorrect. John Corby has confirmed that the original weight of 1200kg was incorrect and has now supplied the correct bulb weight.
The changes have already been updated on the ISA online listing of ECHO and IRC handicaps and owners have received their new certificates.
As part of the ISA’s service to the ICRA and WIORA Championships the ISA Racing Department has advised the Organising Authority that the change to the rating of these boats was due to an error. As a result these new ratings will be used for the regatta which starts from Fenit in Tralee Bay on Wednesday the 13th June.
