The Royal Ocean Racing Club (RORC) in London says a 'correction is needed' over information contained in an article following an ORC presentation at the ICRA Conference in Limerick, a week ago. Michael Boyd, the Commodore of RORC, says the offshore body 'read with interest', and 'some confusion', the press release by the ORC. Boyd says he feels 'very strongly' that information put forward by Dobbs Davis, Chairman of ORC’s Promotion and Development Committee, 'needs correcting'.

In a statement issued by RORC, who administer the rival IRC system, the club says: 

First, the numbers presented are wrong. Dobbs quotes the number of ORC certificates in total up until the end of the year, but only quotes the number of boats in IRC until the end of August of 2015. These are very different figures. Dobbs quotes 4958 for IRC in 2015 but the real number of certificates for the whole year is 7721. That makes the graph look very different and makes IRC the largest individual system in 2015 with ORC Club behind it at 7404 and ORCi trailing at 2492.

It should also be noted that both IRC and ORC are International Rating Systems recognised by World Sailing and IRC is currently in discussions with World Sailing about having its own World Championship. Rather than having two world championships for offshore boats, we are supporting the WS initiative to have one jointly scored IRC/ORC world championship which will allow the event to travel to other continents.

IRC is expanding with new territories in India and Taiwan, growth in Japan and China and very encouraging numbers for the start of the year from many Northern European countries.

IRC is also flexible and not limited to using time-on-time scoring - as has also been suggested. A simple time-on-distance calculation can be applied to create a time-on-distance value, should race organisers want to use it. Similarly, crew number or crew weight can be applied depending on the race organiser’s needs and wishes.

IRC is doing a great job for our sport – you only have to look at the style of boats that have developed since the demise of IMS (the basis of ORC) to understand that IRC is a progressive rule – with the latest generation of boats being fast, safe and fun to sail. Our goal is to ensure that we provide a first class service and develop a product that is constantly evolving to make sure that racing under IRC is as fair as is possible.

The Star keelboat is a 6.9 metres (23 ft) one-design racing keelboat for two people designed by Francis Sweisguth in 1910.

The Star was an Olympic keelboat class from 1932 through to 2012, the last year keelboats appeared at the Summer Olympics at which Ireland's representatives were Peter O'Leary and David Burrows.

Ireland has performed well in the class internationally thanks to some Olympic campaigns including a bronze medal at the Star World Championships in 2000, won by Mark Mansfield and David O'Brien.

The boat is sloop-rigged, with a mainsail larger in proportional size than any other boat of its length. Unlike most modern racing boats, it does not use a spinnaker when sailing downwind. Instead, when running downwind a whisker pole is used to hold the jib out to windward for correct wind flow.

Early Stars were built from wood, but modern boats are of fibreglass and carbon construction.

The boat must weigh at least 671 kg (1,479 lb) with a maximum total sail area of 26.5 m2 (285 sq ft).

The Star class pioneered an unusual circular boom vang track, which allows the vang to effectively hold the boom down even when the boom is turned far outboard on a downwind run.

Another notable aspect of Star sailing is the extreme hiking position adopted by the crew and at times the helmsman, who normally use a harness to help hang low off the windward side of the boat with only their lower legs inside.
