British boat owners who hold a current Spinlock IRC certificate, and who have their boat weighed by a RORC measurer in the UK, will have the certificate amendment fee deducted from their invoice. 

Although official weighing and measurement is not required for Spinlock IRC unless you need an Endorsed certificate (where the data has been officially verified; weighing is usually optional for production designs), many owners like to take advantage of the service to ensure that the data on their IRC certificate is as accurate as possible.

Terms & Conditions

a)        Only GBR boats holding a full IRC curren tcertificate (not SER) are eligible.

b)        Boats weighed overseas by a RORC measurer are not eligible.

c)         If a boat is weighed more than once in the season, this offer only applies to the first weighing

d)        Where the amendment fee is paid in advance, the amount will be deducted from the weighing invoice. 

e)         If the amended certificate is needed within 5 working days of the application, necessitating an Expedited amendment fee, the amount refunded will be the standard fee.
