Why ORC?

The real-world problem ...

  • Racing different boats together!
  • Boats don’t perform the same way in all conditions
  • Light-air, heavy air, upwind and downwind all favour different designs
  • Yet we usually rate boats with a single “average” number
  • Which means results can feel… odd, depending on the day

Local Issues

  • Fleet numbers decreasing throughout Ireland.
  • Minority of boats winning everything in single handicap systems.
  • Competitive Spinnaker fleets much reduced.
  • Disillusionment with lack of transparency and imbalance in single-number handicaps.
  • Older boats becoming very uncompetitive

How ORC Works

  • ORC starts by measuring your boat and sails in detai
         – 000’s of boats measurements already there
         –
    Sail data via IRC Cert / sails tag / sailmaker
  • ORC builds a performance model of how your boat really sails
  • It predicts how your boat sails in different winds and angles
  • It uses that model to calculate race corrections for real conditions
