ORC Grand Prix Classes Part 1 - General 101. It is the intention that the rules and specifications for the ORC Grand Prix Classes provide close

racing without time allowance in grand prix competition and that the yachts designed to this rule be fast, sound and seaworthy, retaining thereby, with a minimum of modification, good value beyond their competitive life as grand prix racers.

102. The authority for the rules of the ORC Grand Prix Classes is the Offshore Racing Congress

(ORC) and the rules shall be maintained and administered at ORC discretion. 103. To be eligible for entering in any race or event in which scoring for ORC Grand Prix Class

yachts is provided, an ORC Grand Prix Class yacht shall hold and comply with a valid Class Certificate.

104. For racing within Class, advertising as provided under ISAF RRS Appendix G, Category C is

allowed. 105. Measurement & Class Certificates. Neither an IMS hull measurement nor an IMS Certificate

is required. However, except where otherwise stated, the measurement prescriptions of the International Measurement System shall apply as may be appropriate to the particular measurements specified under these Class rules, including IMS 105 and, in general, provisions for preparation for measurement, measurement trim condition (but as defined for Grand Prix Classes in 401 below), freeboard, sail and rig measurement.

All measurements specified by these Class rules shall be recorded by the Measurer and displayed on the Class Certificate. Except where a change in a measurement value is found to be within tolerances specified in the Class rule, changes in any of the yacht’s rule dimensions or weights shall require re-measurement accordingly and a new certificate shall be issued. At least one yacht shall be checked for compliance with certificate weights and freeboards at major national events and at all international events (see also Part 4, Displacement, Freeboards & Stability).

A yacht may hold only one valid Class certificate at any time. The number of valid certificates issued for a single yacht as a result of revisions to the yacht is limited. Within the 12-month period beginning 1/1/2007, the maximum shall be four such certificates. From 1/1/2008, the maximum shall be two such certificates within any 12-month period.

Part 2 - General Limits & Exclusions 201. Unless otherwise indicated, specifications below are metric. For the purpose of testing

compliance with specifications, no rounding of measured and calculated values is implied, e.g., where a limit is given as maximum 12.5, a measured value of 12.501 would not comply. All measurement for ORC Grand Prix Class Certificates shall be under the metric system and certificates in any case shall be issued in metric units. Measurement shall include a written record of the yacht's compliance with all provisions of the Class Rule not otherwise displayed on the Class Certificates.

202. Permitted materials -- Hull, Deck & Panels. In the construction of the hull and deck

structures and in interior panels, except for hardware, fastenings and keel support structures, only the following materials are permitted as listed by Class (see also 209.6, keel construction):

3. Carbon Fiber. Where carbon fiber is incorporated in the construction of any spars on the yacht, this shall be limited to High Strength carbon as defined in IMS Regulations 1B and the walls of the spar shall not be of cored construction.

4. Spreader sets. Jumper struts and stays are not permitted. For the GP 33 and GP 42 there shall be two spreader sets. For the GP 26 there shall be one spreader set. For all classes, the sweep-back angle of spreaders shall be not less than 15 degrees. Curved spreaders are forbidden.

5. Poles & Sprits. For the GP 42 and 33, spinnaker poles are permitted and sprits are not permitted. For the GP 26, sprits are permitted, spinnaker poles are not permitted and any headsail flown shall at all times be tacked at the centerline of the yacht. Halyards locks are not permitted.

502. Standing Rigging. Except for the permanent backstay, all standing rigging shall be of stainless

steel rod or twisted stainless steel wire and subject to the limitations set forth below. Titanium is not permitted in any purpose.

1. Backstay. Backstays are limited to a single, permanent backstay, which may be of stainless

steel or composite fiber construction. The backstay may be adjustable. From the upper attachment point of the backstay there shall be a single part only, of length not less than “P”, the intention being to prohibit any configuration which might simulate double backstays. Below the lower end of this single part, the backstay configuration is unrestricted except that the fixed anchor point of the backstay configuration shall be not higher than 200mm above the working deck.

A “fixed anchor point” is any point where a block or the end of any rope used to tune the backstay is attached. When in tension, the backstay shall form a straight line between the top (mast crane) and bottom fixed anchor attachment points. The centre of any bottom fixed anchor point shall be not be above a horizontal plane which is established 0.6 m (GP26), 0.72 m (GP33), 0.8 m (GP42) from the waterline in measurement trim.

Pre bent backstays and/or any system to artificially increase the distance between the straight backstay line and the mainsail roach is not allowed, except for soft battens “flippers”.

2. Forestay. Except for backstay adjustment, means for adjusting forestay tension while racing is not permitted. Any luff-groove device shall not exceed the maximum FSP (see Table of Measurement Limits) and shall not incorporate carbon fibers in construction.

503. Backstay Gantry. The shortest distance between the upper measurement point of “P” at the aft

face of the mast and the center of the attachment point of the upper end of the backstay shall be recorded as Gantry Overhang Aft (GOA). GOA shall not exceed the maximum given in the Table of Measurement Limits.

504. Chain Plate Width. The distance between the centers of the outboard chainplates (CPW) shall

be recorded and shall be not less than the minimum given in the Table of Measurement Limits. 505. Sail Measurements. Sails shall be measured in accordance with IMS Rules with exception that

maximum of five battens are permitted in the mainsail, four battens are permitted in a jib and no battens are permitted above MGT.

Measurements that are limited are defined in the Table of Measurement Limits and the largest measurements found among the sails shall not be greater than respective limits in the Table of Measurment limits

506. Sail Inventory. Exclusive of storm sails required by the ISAF/ORC Special Regulations, sails allowed on board while racing are limited by Class to the following:

GP 26: 1 Mainsail 2 Jibs

2 Asymmetric Spinnakers

GP 33: 1 Mainsail 3 Jibs 2 Spinnakers (either type or both)

GP 42: 1 Mainsail 4 Jibs 1 Staysail 3 Spinnakers (either type or both)

507. Sail number limitation per year. In addition to standard ORC stamp, all sails shall be

stamped by official GP class measurement stamp where sail number, date of measurement, name of measurer and type of sail with appropriate identification per year will be recorded. First set of sails shall be measured in the same year when boat is launched. Maximum number of sails measured in one calendar year (January 1st – December 31st) for boat when participating to the official GP 42 Circuit is defined as follows:

GP 26: 2 Mainsails 4 Jibs

4 Asymmetric Spinnakers

GP 33: 2 Mainsails 5 Jibs 5 Spinnakers (either type or both)

GP 42: 2 Mainsail 6 Jibs 1 Staysails 6 Spinnakers (either type or both)

Damaged sails can be repaired, but than shall be re-measured and re-stamped with both ORC and GP measurement stamp where same sail identification will be used.
