and talking about the growing interest in ORCI in these times of crisis:

"There were 119 entries in the 2011 ORCi World Championship in Cres, 135 at the 2012 Audi ORCi World Championship in Helsinki, and here in early April it is a number that is approaching fast for organizers of the ORC World Championship 2013 in Ancona, Italy.

While many sailing events around the world have struggled to keep up their participation levels, this year event organizers in Ancona have the opposite problem: they have put a limit on entries, the first time ever for an ORC championship event.

"Our host venue at Marina Dorica is a fantastic facility," says racing manager Paolo Massarini. "But with more than 130 boats from 12 countries we could not guarantee space for everyone, which includes proper accommodation for the boats but also the crews and their families and friends. Comune di Ancona and the Regione Marche have been very helpful to anticipate a large crowd of over 1000 people coming to this event, so we have to be realistic in making sure there is space for everyone....

Another reason to limit entries is that a race fleet that is too large can also compromise the quality of racing within the format allowed by the International Sailing Federation (ISAF). Since only two World Championship titles can be awarded according to ISAF rules, the large fleet can be split into only two separate regattas to determine a winner for each. At up to 70 entries in either class, this will still be quite a large group for Principal Race Officer Alfredo Ricci and his team to manage to race in a way that gives a fair chance to every participant. Formats such as multiple course areas are being considered to handle the large fleet.

"Fairness is extremely important at the World Championship," says ORC Chairman Bruno Finzi. "There are many boats coming from not only the Mediterranean region but from all over the world, with most making a tremendous investment in their preparation to compete. So it is important that we make sure that all aspects of the competition are fair and transparent: the measurements, the ratings, the race courses and the scoring must be absolutely clear to all who participate."

ORC - World Leader in Rating Technology

As a result of having the complete matrix of predicted boat speed at various wind strengths and directions, ORC rating systems can therefore provide a variety of methods to calculate corrected time. Scoring options offered include the most sophisticated, where the boat's performance is taken in consideration depending on the wind conditions, but also simple scoring options using single number scoring coefficients in either Time on Time or Time 0n Distance formats. Simple scoring options also include Performance line as a combination of Time on Time (ToT) and Time on Distance (ToD). There is also the Triple number system that uses three different Time on Time coefficients to be used in light, medium and heavy breezes. All simple scoring options are also given for either Inshore (windward-leeward) or Offshore races.

This wide variety of scoring options may look complex, but it is actually one of the strength of the ORC rating systems to offer race managers a variety to choose from that best suits their fleet, their race type and their race conditions. The factors race managers should consider when choosing which scoring type to use include:

type and level of the fleet - better to use simple systems for club-level racing

type of race- windward/leeward or an offshore race

the difference between fastest and slowest boat - important to know how to

divide classes and to combine entries for overall prizes

prevailing weather condition- are they steady or variable during the race

tradition of particular type for eg, Time on Time or Time on Distance

is there current in the area, and can it be predicted - if not, then ToT is better than ToD

Because the ORC VPP can predict the performance potential of different boat types, it can rate them fairly against each other in any range of wind conditions and course types. In this way Performance Curve Scoring can make handicap yacht scoring significantly more fair than any single number scoring approach.

Last year in Helsinki it was like this:

Boats everywhere. I guess that if this continues to grow they have to run qualification races for the world championship. That's unavoidable with the growing interest on ORCI.

Two years ago in Australia:

We talked to Matt Allen pre-Hobart about the two rules.

He explained ‘ORCi addresses stability issues where IRC doesn’t. The ORCi stability index is derived from the old IMS stability index which is something that we all know and trust in a comprehensive fashion. It’s used today to determine whether boats meet the stability requires for the Hobart race.

‘ORCi is a transparent rule while IRC is not. There are pros and cons for each rule.

‘I think also measuring the stability is a good thing as long as stability is encouraged. We don’t want to go back to sailing tippy boats. IMS, people thought it was in some respects a good rule but didn’t encourage boats to be stable and didn’t move with the times and possibly didn’t encourage boats to be quick as much as one might have wanted them to be.

‘I think IRC encouraged quick boats at 50 foot plus and has traditionally not encouraged boats under 50 feet or under 45 feet to be all that fast.

‘There is a comment from a lot of countries where they believe that the racer cruiser is more fairly treated in ORCi than IRC.

'They tend to think that some production boats do well under IRC while other brands do not seem to be nearly as well handicapped. Under ORCi they are possibly more evenly treated. ...

Dobbs Davis from the Offshore Rating Council commented ‘ORC seems to be doing a better job across a broader range of boat types than some of the other rating rules. ...

‘Back in the days of IMS in the late 90s and early 2000s the measurement of stability was there but it was not accurately modelled in the performance of the VPP so the designers have worked around it.

‘That's been gone since 2007 when the ORC invested heavily in better analysis to produce much more accurate results.

‘Under ORCi Fast boats do fine and slow boats do fine. That's the challenge of all these rules, to make them work across the range of boat types. It is a challenge for sure but based on the results that we saw from the recent World Championships where we had 119 boats from 16 countries and in which we had that broad range of boat types, it seems to be working and it seems to be fair.

‘Owners are dissatisfied with strong type forming in the rules. The analysis we did from the last Worlds results show, are not strong type forming tendencies that the ORC type system might work as a good alternative across boat types but most importantly is it offers flexibility. ...

‘It’s a scientific based system with no politics, no guessing. The rule is downloadable.

‘Boats are entering ORCi because they get a certificate anyway to get the stability.

ORC - World Leader in Rating Technology

The Royal Ocean Racing Club (RORC) and Union Nationale pour La Course au Large (UNCL), joint owners of the IRC rating rule, have been in discussion with the Offshore Racing Congress (ORC) about the possibility of creating a unified organisation to govern yacht ratings worldwide. This initiative to bring the world offshore rating systems together was endorsed by ISAF following its AGM in 2009 in Korea.

The intention is for RORC/UNCL and ORC to create a joint venture company which would run the existing rules, IRC and ORC and then in time, using the combined knowledge and resources, evolve new rating systems that combine the benefits of IRC and ORC to create fast, fun and seaworthy boats for unified competition all over the world.
