Amended Certificates

If you change anything on the boat, or buy new sails etc. that may affect your IRC Rating, you will need to apply for an amended certificate.  You can make any number of changes for the price of one amendment.

If you are not sure whether a change you are making will require an amended certificate, PLEASE CHECK .  In some cases we may just ask you to write us a note about a change which we can keep in the file for our information. 

Common changes which require an amended certificate are :

• new sails, either larger or smaller

• addition or removal of sails

• new or changed rig details

• added or removed internal ballast

• keel change

• hull change, eg. fairing of IOR crease

• weighing/measurement

If your certificate is Endorsed and you wish to keep the Endorsed status, we will usually require official verification of the new measurements. For instance, if you are having new sails it will save time if you ask the sailmaker to let you (or us) have the new measurements in writing.  In other cases we may require a measurer to check new measurements.

We reserve the right to refuse to amend a certificate if we believe that the amendment is intended to take advantage of specific race conditions (eg. rating with a No.3 only, two days before a weekend when it is forecast to be windy!)
