IRM at the Boat Show

RORC presentation and owners association formed

The RORC Rating Office gave a presentation of its new(ish) IRM rule at the London Boat Show. James Dadd and Mike Urwin went through the sales pitch - type-forming rule to generate light, stable, fast boats with plenty of sail area - for an audience of around 50 people on Thursday 11th January.

James Dadd also explained the basics of the measurement process, the various stages of weighing, shore measurement in a cradle, an inclining while afloat, and mast and sail measurement. All of which was reckoned to take, for the organised and well-prepared boat, two to three days.

There are short-cuts available, if the boat has a measurement certificate from another rule figures could be taken from it - inclination numbers from an IMS certificate or weight from an endorsed IRC certificate were examples quoted. There are also several one design classes for which standard measurement files are held, and so the whole process is a lot quicker and cheaper; 1D35, Farr 40, IC 45, Mumm 30, Mumm 36, Prima 38 and Sydney 40. The cost of measurement is also being held down, with a £200 discount in place it's reckoned that a 9 Metre boat would cost less than £300 to get racing. And you get an IRC certificate into the bargain.

For next season the charge onto the water will almost certainly be led by the Ker/Race 1 11.3 M boats, of which eight are now confirmed as sold. There is also a Christian Stimson designed 12.5M which should be ready for the Warsash Spring Series. This will kick off a season's racing, some of which will constitute an IRM championship circuit - events include the RORC Myth of Malham, Morgan Cup, IR2000 Championships, the Berthon Source Regatta and Skandia Life Cowes Week. There will be two divisions, split at the TCM of 0.990. The meeting was followed by the formation of an owner's association for the class.
