IRC

IRC is a measurement system designed to cover a wide range of racing and cruising monohulls by attributing a rating based on corrected time, enabling them to race against each other on an equal footing. The rules are co-managed by the RORC in Great Britain and UNCL in France. Each yacht has a handicap (TCC) calculated on the basis of various measurements on the boat, it’s size, bow, keel, displacement, sail area… The calculation method is secret in order to prevent designers from exploiting potential loopholes in the rules.
From a competitor’s point of view, the aim is of course to have the lowest possible handicap and the fastest boat. 

All Purpose works constantly on the optimisation of IRC sails. Every change is submitted to the IRC Rating Office which calculates the new TCC.

The entire team at every All Purpose loft races in IRC. Sailmakers are available to skippers to help optimise sail trim and configurations for IRC.
