July 2007

A modification to the International A Class excel spreadsheet has been published on the Tech area of this site.
Following calculated values "as advice to measurer" : "Maximum foot length for other headsails" and "Maximum value of spinnaker foot and widths" are wrong in current official 2004 version published on RSD website.
Note that above mentioned values DO NOT affect the boats rating. They would only be relevant to other headsails and spinnakers which are very seldom used on radio "A" class boats. Ratings calculated according to 2004 version of the Excel file are correct. Certification Authorities of DMs are advised to use in the future the new 2007 version of the Excel file and to inform measurers and owners of the certificates issued with the Excel file -2004 version that ONLY those using other headsails and spinnakers may be affected.
