PART A – RULE POLICY 1


INTRODUCTION 1.1


The Rule is in two parts, Part C, IRC, advertising permitted, and Part D, IRC, advertising not permitted. IRC is a rating rule based upon owner-supplied information and will remain unpublished. The emphasis is on simplicity and concise rules.


2 2.1 FUNDAMENTAL POLICY


IRC is a system of measurement which classifies a broad range of cruising and racing ballasted monohull keel boats for competition by providing ratings comprising single figure allowances based on time. Except for designs first rated before 1 January 2016, boats shall have a minimum hull length of 5.00m.

2.6 2.7 The IRC concept protects the existing IRC fleet.


IRC encourages design innovation consistent with stability, rounded performance, seaworthiness and safety.


IRC discourages unnecessary expense at all levels.


The spirit of IRC requires that owners and designers shall not seek means of artificially reducing the rating of a boat, e.g. increasing performance without a corresponding increase in rating.


Calculation of IRC ratings is unpublished and based on measurement and data input only.


IRC ratings may rely on owner submitted data (see Rules 8.5 and 9) but a Rule Authority (as defined in Rule 4.1) may require that boats be weighed and measured by an appointed measurer for certificates issued under their jurisdiction. Some or all of the dimensions of class production boats may be standardised.


Any exploitation of the inherent simplicity of the IRC Rule will be discouraged. The RORC Rating Office and UNCL therefore reserve the right to make adjustments or amendments to any part of IRC at any time in order to prevent undesirable or unforeseen lines of development.


IMPORTANT NOTICE


The safety of a boat rated under IRC and its entire management including insurance shall be the sole responsibility of the owner/ competitor who must ensure that the boat is fully found, thoroughly seaworthy, and operated by a crew sufficient in number and experience who are physically fit to face bad weather. The owner/ competitor must be satisfied that: 3.1.1 The hull, hull appendages, spars, rigging, sails and all gear are sound.


3.1.2 All safety equipment is properly maintained, stowed and in date.


3.1.3 The crew know where such equipment is kept and how it is to be used.
