The RORC Rating Office acting as the GBR IRC Rule Authority will be introducing a new initiative in GBR in 2013. Owners who only enter one or two IRC races a year will be able to apply for an IRC Limited Validity (LV) TCC at a reduced price. The cost of an LV TCC in 2013 will be £1.50 per metre LH plus £5.00 per day of validity. An example cost comparison for a 10 metre boat entering a single 4-day event would be: Standard IRC certificate £101.50 (online fee), LV TCC £35.00. In addition, if an owner subsequently wishes to upgrade to a full IRC certificate a discount will be applied to the application fee.

The LV TCC is not available to boats that hold a current valid certificate, and is defined as "an IRC TCC issued by the IRC Rating Authority for use by a boat for a race or regatta (or part of) comprising races run over not more than nine consecutive days including any lay days". Boats will be limited to holding two separate LV TCCs per year.

The TCC will be compatible with standard IRC ratings so that Clubs can incorporate boats into their IRC classes with no changes other than some extra words in the Notice of Race. However, no certificate will be issued and the boat will not appear on the online IRC listings; clubs and events that have been approved to accept LV TCCs will receive a list of the ratings specific to their event. Clubs are encouraged to consider LVs for their main events and contact the Rating Office in good time if they want to participate.

More details and the full terms and conditions can be found on the RORC Rating Office website.
