ORC Rules for 2012 available online

by Offshore Racing Congress on 29 Dec 2011
. .
ORC Rules 2012.

The Offshore Racing Congress (ORC) have today, 28th December, announced its rules for 2012 are now available for download online.


These rules include the International Measurement System (IMS), the ORC Rating Rules (ORC International and ORC Club), the 'Green Book' of ORC Championship Rules, GP Class Rules, the ORC Speed Guide, and ORC Stability and Hydrostatic Datasheet.

The ORC VPP Documentation will be updated in early 2012 once the final version of the 2012 VPP is beta-tested fully and ready for release by the International Technical Committee (ITC), and the Offshore Special Regulations for safety are also revised and available from the International Sailing Federation here.

Except for some areas of the Southern Hemisphere such as Australia, Argentina and Brazil, these rules go into effect after 1st January 2012.

'We’re very pleased that the ORC staff have once again finished their revisions taken from the Annual General Meeting of the Congress last month to make these rules available by the first of the year,' said Bruno Finzi, Chairman of ORC. 'These rules not only represent the 40 years of accumulated experience at ORC, but they also show through the submission process how we can help the system evolve to be most accurate and relevant for the modern offshore sailor.'

Changes to the VPP in the 2012 Rules include the following:
• New hydrodynamic treatments to address longitudinal crew weight positions, better calculations of L for manual single rudders, an output available for ‘light ship’ trim, and a better routine to treat declared displacements for ORC Club certificates;
• Better treatment of the shape function to evaluate spinnaker heights, and a new twist function for depowering jibs;
• A revised Dynamic Allowance reducing its effect on non-cruising boats;
• A new formulation for the offshore single-number scoring coefficients;
• Removal of anchor and chain weight gyradius credit;
• Windward/Leeward courses are calculated now without wind averaging.

Changes to the IMS include:
• Boats over 24 m in length may be measured with onboard equipment required for IMS but impractical for removal for measurement, with adjustments to freeboards and inclinations of about 1 degree allowed, subject to approval and verification by the Chief Measurer;
• Updated definitions have been made of rigging features such as Inner Forestay, Fiber rigging, Mainsail furler, and Genoa furler;
• A clarification is made to prevent headsails and mainsails to be made with top girths greater than lower girths;
• Use of LCF is introduced for the position of the two poles in the inclining test.

Changes to ORC Rating Systems include:
• Spinnakers and Code 0’s may not be attached to the headstay;
• Use of spinnakers and jibs on poles is clarified;
• The definition of GPH is now used solely for reference purposes, not scoring.

Changes to the Green Book include:
• New standards needed to host ORC championship events, with a new Checklist to use for guidelines;
• New guidelines offered for Owner/Driver Trophies;
• New offshore race scoring options to include one long offshore race having a 1.5 points score weighting, which includes a short offshore race of 1.0 points weighting; or two separate offshore races scored as 1.0 points each;
• Measurement inspections will be conducted during events, with emphasis given to well-placed boats in the results.

The accumulated effect of these rule changes is minor – less than 0.5% on the ratings of most of the 2000 boats in the ORC test fleet – but they seek to further refine the accuracy of the rating system’s use worldwide. In 2011 nearly 8000 ORC International and ORC Club certificates were issued by rating authorities in 35 countries.

New and revised rules are indicated by margin bars in each rules documents, and a complete summary of the changes can be found here.
