Part 1 - GENERAL 100

Rule Philosophy The ORC Superyacht Rule uses the IMS (International Measurement System) and ORC VPP (Velocity Prediction Program) modified to cover all the features and special characteristics of superyachts in calculating the yacht’s predicted speed in different wind and sea conditions. With this information ratings are calculated and used for corrected time calculations in scoring of races of yachts of different sizes and characteristics.

Beside its scientific background, the main principle of the rule is transparency. Copies of certificates are available at the ORCsy website and each owner or representative has the ability to check the effects on their rating when changing any measurement value using the ORCsy ‘Sailor Services’.

101

Superyacht Definition A superyacht is defined as a yacht with length overall (LOA) greater than 30.48 m (100 ft). However, smaller yachts can also be measured and rated under this rule when a regatta organizer’s eligibility criteria enables smaller yachts to compete in their superyacht fleet.

102

Authorities The sole authority for the ORC Superyacht Rule is the Offshore Racing Congress and it shall be maintained and administered at the ORC's discretion.

103

Administrative

103.1

The official language of the ORC Superyacht Rule is English and in case of dispute over translations the English text shall prevail.

103.2

The word "shall" is mandatory and the words "may" and “can” are permissive.

103.3 Except where used in headings, when a term is printed in “bold” the definition in the Equipment Rules of Sailing (ERS) applies and when a term is printed in “italics” the definition in the Racing Rules of Sailing (RRS) applies.

103.4 When printed in "bold italics" the term is used as measurement taken or recorded by the measurer.

104

Rules Interpretations The ORC Superyacht Class Technical Committee may at any time issue interpretations or corrections of the ORC Superyacht Class Rule. Any such interpretation or correction shall be published and then deemed final unless and until overruled by the ORC Management Committee and Congress.

202

Stability measurement The boat’s stability shall be derived: a) If there is measured hull offset file from the inclining test perfomed using the boom as an extension arm as defined in the IMS Rule E2.2 with minimum of 1 degree heel to be reached b) If there is no measured hull offset file, then from the data available in the stability booklet

203

Rig measurements

203.2 If there is a mainsail furler in the boom, this shall be recorded as “YES”, and if not a “NO”.

204

Sails measurements

204.1

Sails measurements shall be taken according to the IMS Part G with additional measurements as follows:

204.2

If a headsails is set on the furler, this shall be recorded as “YES”, and if not a “NO”.

204.3

For each headsail, if it is furled more than 50% while tacking this this shall be recorded as “YES”, and if not a “NO”.

204.4

Number of furled headsails (not deployed) when sailing upwind shall be recorded.

204.5

For any unconventional sail not measured as a main, mizzen, mizzen staysail, headsail or spinnaker, the area shall be recorded as calculated from the sail dimensions as definded by the ERS. The use of such a sail shall be recorded as: upwind, downwind or both.

204.9

Use of a mizzen staysail shall be declared as one of three options: with headsail, with spinnaker or with both headsail and spinnaker.

Part 3 - RATING 300

Racing Trim

300.1

The ORCsy VPP (Velocity Prediction Program) is used to calculate ratings from a boat’s predicted performance in various wind and sea state conditions. VPP calculations are made with the yacht in racing trim, describing as close as possible to the actual condition in which yacht is sailing. The racing trim is derived from the measurement trim and the detailed inventory list as defined in Rule 201.1.

300.2

If the hull offset file, freeboards and stability are completely measured this is marked with “M” on the ORCsy certificate and displacement in the racing trim is calculated from the hull geometry and measured freeboards and a) deducting the weights that are declared not to be on board while racing and; b) adding the weights that are declared to be on board while racing but were not on the boat during the measurement.

300.3

If any of hull offset file, freeboards or stability are not measured measured this is marked with “D” on the ORCsy certificate and displacement is calculated starting from the light ship trim from the stability booklet and: a) adding default weights for racing gear, crew, sails and declared values for liquids, anchors & chain.

The default evaluation of the weights to be added to the light ship displacement are underestimated not to unduly favour boats not completely measured and b) righting moment taken from the stability booklet is increased by 5%

300.4 If any of hull offset file, freeboards or stability are not measured and stability booklet is not available, displacement and stability data can be taken from any other source and racing trim and righting moment will be evaluated by the rating office where rating penalty may be applied to the uncertainty of data provided. If new data becomes available certificate may be updated.

300.5 Tankage values shall be declared by the deadline established by the ORCsy Technical Committee and/or Event Organizer. If not declared all tankage shall be taken as 10% full.

301

Use of Headsails

301.1 Headsails may be set on the forestay or set flying.

301.2 Headsails set flying may be tacked: a) in front of the forestay, when i) ii)

it shall be tacked approximately on the boat’s centerline it shall not be used when any spinnaker is set

b) between the forestay (included) and the forward mast, when i) it shall have HLP <= 1.1*J ii) it shall be tacked inside any spinnaker sheet iii) it may be tacked out of the boat’s centerline 301.3 When more than one headsail are used at the same time, if they are trimmed flat along the centerline of the boat, and the clew of the foremost-tacked headsail is forward of the clew of any other headsail trimmed in the same way, the measurements of the largest headsails set on the forestay shall be taken as follows: a) HLP shall be the distance between the aftmost clew and the foremost headstay b) HLU shall be the luff of the foremost headsail The resulting area of the largest headsail set on the forestay will be reduced by 5% if there are 3 or more headsails used at the same time.

302

Observed Performance Factor (OPF)

302.1

The yacht’s rating may be adjusted by the Observed Performance Factor (OPF), which can be applied by the ORC when: a) there is evidence from the race tracking data and/or from observed performances and timings that the yacht’s elapsed time is grossly different from that predicted based on the rating allowances published on the certificate. b) the data and measurement information from the handicap application form is insufficient to provide a detailed assessment of the yacht’s speed potential or is submitted late.

OPF will not be applied in those cases where a yacht’s performance is clearly affected by tactical mistakes or poor boat handling, as determined by GPS tracking and/or visual observations.

302.2 When the OPF is applied to a yacht that has a valid certificate, that certificate shall be withdrawn and replaced with a new one that will adjust all time allowances based on the assigned OPF. If the OPF is applied during a regatta, the races scored with the withdrawn certificate shall not be re-scored and the new certificate, modified with the OPF, shall apply only to the races thereafter.

302.3 The decision to apply an OPF, or not, is at the sole discretion of the ORC and can not be grounds for seeking redress. This changes RRS 62.1.

Part 4 - CERTIFICATES 400

Certificate Request

400.1

A request for an ORC Superyacht certificate shall be made by completing the on-line application form at the ORCsy website. The application shall be submitted no later than 4 weeks prior to the first day of registration of the event, unless otherwise stated in the regatta’s Notice of Race. The ORC may extend this deadline at its sole discretion.

401

Certificate Issuing

401.1

Certificates shall be issued by the ORC Central Rating Office. A levy, as determined by the ORC, shall be paid for all valid certificates issued.

401.2

The Rating Office shall have the authority to issue the certificate upon receipt of the measurement data, but if anything that can be considered unusual or against the general interest of the ORC Superyacht Rule is found, the Rating Office may withhold the certificate pending an examination of the case and issue a certificate only after approval is obtained from the ORC.

401.3

The certificate shall be valid until the date printed on the certificate, which shall normally be the 31st of December of the current year.

401.4

A yacht shall have only one valid certificate at any one time. The valid certificate shall be only the last one issued.

401.5

The certificates, once issued, are considered public, and copies are available to all superyacht owners or their representatives registered through the ORCsy Sailor Services website.

402

Owner’s Responsibility

402.1

The owner or his representative shall be responsible for: a) Preparing the yacht for measurement in accordance with the ORCsy rule b) Declaring any required data to the measurer and/or on the handicap application c) Ensuring compliance of any measurement data to those printed on the certificate. Compliance with the certificate shall be defined as follows: i) All measured, declared or recorded values shall be as close as possible to those on the certificate.

Differences are allowed only if the values on the certificate give a less favorable rating. ii) The sail area shall be smaller or equal to the respective one printed on the certificate.

d) Using the yacht and equipment as prescribed by the RRS and ORC Superyacht Rule.

402.2 A certificate shall be automatically invalidated by a change of ownership. The new owner may request a new certificate with a simple declaration that no changes have been made so a new certificate may be issued without the need to submit a new handicap application or conduct any new measurement.

Conversely, the new owner has every right to have the boat re-measured.

402.3

Any change of the measurement data requires declaring all changes and/or a new measurement at which time the ORC will issue a new certificate. Examples of changes include: a) Changes of ballast in amount, location or configuration. b) Change of tankage, fixed or portable, in size or location. c) Any changes in the engine and/or propeller installation. d) Any change to the size, cut or shape of the maximum area sails. e) Changes to the shape of the yacht's hull and/or appendages f) Changes to spars or standing rigging configuration g) Any other change of the data listed in the handicap application and certificate that affects the yachtâ&#x20AC;&#x2122;s rating.

403

Certificate Compliance

403.1

When, as a result of inspection, measurement check or a discovered error, it is determined that a yacht does not comply with her certificate: a) Prior to or between regattas, if the non-compliance is determined not to be the fault of the owner or his/her representative, the certificate shall be withdrawn and replaced with a new certificate that reflects any new measurement data. b) If the non-compliance is discovered during a regatta, a new certificate will be issued, and all races in the series going forward shall be scored using the new certificate rating values. Whether any or all completed races scored using the old certificate are to be re-scored with the new certificate will be at the sole discretion of the Race Committee. c) If the the non-compliance is determined to be the fault of the owner or his/her representative, the certificate shall be withdrawn and replaced with new certificate that reflects any new measurement data, and the matter shall be refered to the Protest Committee. Nothing in this paragraph shall bar action under the RRS concerning a yacht deliberately altered to not comply with her certificate and shall not limit in any way acts of the Race Committee and Protest Committee against any individual person involved.

Part 5 - SCORING 500

Ratings

500.1 The ORC Superyacht Rule provides rating time allowances expressed in s/NM for light, lightmoderate, moderate-strong and strong wind speeds in both flat water and rough water conditions. Time allowances in s/NM are used for Time on Distance (ToD) scoring method while for Time on Time (ToT) scoring, coefficients are calculated as ToT = 500 / ToD for each time allowance respectively.

500.2 Corrected times using Time on Distance scoring method are calculated as follows: Corrected time = Elapsed time â&#x20AC;&#x201C; (ToD * Distance) 500.3 Corrected times using Time on Time scoring method are calculated as follows: Corrected time = ToT * Elapsed time

500.4 Corrected time shall be displayed in days:hours:minutes:seconds. When calculating corrected time, the boat's elapsed time shall be translated to seconds, calculations shall be made and results shall be then rounded to the nearest second (for example: 12345.5 = 12346 seconds). This time in seconds shall be then put back in days:hours:minutes:seconds format.

500.5 Wind ranges for the different rating coefficients are as follows: Light 9 kts or less Light - Moderate more than 9 kts and up to 13 kts Moderate – Strong more than 13 kts and up to 17 kts Strong more than 17 kts A reference height for the wind speed is 10 meters above the sea level.

500.6 The sea state for the upwind portion(s) of the designated race course shall be decided by the Race Committee as ‘flat’ or ‘rough’. Rough sea state would be waves approximately 1 – 1.5 meters or higher (trough to crest).

500.7 Decisions regarding the scoring method, course length, wind range and sea state shall be made by the Race Committee and shall not be ground for seeking redress. This changes RRS 62.1. The way of communicating scoring method and selected wind range and sea state will be defined in the Sailing Instructions. The Race Committee will use all resources at its disposal (forecasts, pre-race readings from RC boats, trends etc.) before designating the wind range and sea state for scoring each race.

501

Starting Formats and Scoring Options

501.1 For safety reasons, most superyacht regattas have the yachts start individually with a minimum gap between starts of 30 seconds. The starting sequence shall be published before the start of each race and will depend on the ratings (based on the wind range and sea state), fleet size, course configuration and other safety and fair racing considerations. There are two common starting formats: a) Staggered Start: Yachts can start slowest rated to fastest or fastest rated to slowest. The Race Committee determines the stagger between yachts (usually 1, 2, or 3 minute gaps). Elapsed time for each yacht is calculated from the time of her starting signal to her finishing time. Results are then determined based on corrected times calculated either by the Time on Distance or Time on Time scoring method, as decided by the Race Committee and published in the Sailing Instructions. b) Pursuit Start: The slowest rated yacht starts first. The starting time for each yacht is calculated from the appropriate Time on Distance (ToD) rating and course length. Starting times may be adjusted to be rounded to the nearest 5-second increment (05, 10, 15 etc.) and in some instances further adjusted to maintain the mandated 30 seconds safety gap between starters. Additionally, the starting sequence may be adjusted to accommodate the gapping of class finish times for safety reasons (usually 10 minutes between class finishes). Class results are then determined by the yacht’s actual finishing time with the first boat in class to cross the finishing line winning. i) Shortened course If the course is shortened, elapsed time for each yacht is calculated from the time of her starting signal to her finishing time. Results are then determined based on corrected times calculated either by the Time on Distance or Time on Time scoring method, as decided by the Race Committee and published in the Sailing Instructions. ii) Fleet scoring When scoring fleet results for a multi class regatta with gapped class finish times, arrival times of each class, included in the multi class scoring, are adjusted by the ideal gap finishing time fixed in the starting sequence.

Selection of the starting format and scoring options by the Race Committee shall not be grounds for seeking redress. This changes RRS 62.1.

502

Re-scoring

502.1 Once race results are published, re-scoring of the race can be made only if any yacht’s certificate is reissued in accordance with the rule 403.

502.2

Re-scoring shall be done as follows: a) Staggered Starts: New ToD or ToT scoring coefficients shall be applied for re-calculations of corrected times. b) Pursuit Starts: Finishing times for the yachts for which rating is corrected shall be adjusted using the following formula: New finishing time = Old finishing time + (ToDold â&#x20AC;&#x201C; ToDnew) * course length
