Interest in the ORC handicap system is building among Irish boat owners following recent industry discussion and coverage.

An update from the ORC Ireland convenor says momentum has increased since an initial meeting in Dun Laoghaire.

“ORC remains an open and transparent handicapping system and is worth continuing with,” Fintan Cairns, the Dublin Bay-based convenor, said.

The system is already being accommodated by Dublin Bay Sailing Club (DBSC), the country's biggest yacht racing club, for the 2026 summer season, running alongside existing handicap formats.

At present, Cruiser classes 0, 1, 2 and 3 are included, with scope to extend to other divisions, including sportsboats and non-spinnaker fleets.

ORC Club has also been used in the Brass Monkey series at Howth Yacht Club, where organisers report a strong and positive response from owners.

Results from that series demonstrate the system’s output and race-scoring capabilities.

How ORC compares with the well-established IRC system was examined here by Mark Mansfield, the Cork Harbour–based professional sailor, sailmaker and rating specialist with plenty of reaction here.

An updated information meeting is planned for January, with an in-person event and online webinar to widen access.

The session will outline how ORC Club works, its technical capabilities and possible approaches to implementation and scoring.

ORC is expected to issue certificates for Irish boats in 2026, offering owners an opportunity to trial the system ahead of broader adoption.

A new ORC Ireland website, including online applications and supporting information, is due to launch shortly.

More than 100 Irish boats already appear on the provisional 2025 ORC Club ratings list here.

About the ORC Handicap System and Its Use in Ireland

The ORC (Offshore Racing Congress) handicap system is a measurement-based rating rule used to create fair competition between sailing yachts of different designs. Rather than relying on performance data alone, ORC ratings are calculated from detailed measurements of each yacht’s hull shape, rig, sails and stability. These measurements generate a Velocity Prediction Program (VPP) model, which estimates how fast the boat should sail in various wind strengths and angles. Race results are then corrected using one of several scoring options, such as Time-on-Time or Time-on-Distance, aiming to reward crew performance rather than inherent design advantages.

In recent years, there has been exploration in Ireland toward broader adoption of the ORC system, particularly ORC International (ORCi) and ORC Club certificates.

Clubs on both east and south coasts have explored ORC as an alternative or complement to the IRC rating rule, which has traditionally dominated Irish handicap racing. In 2025, events such as the D2D Race and Calves Week trialled ORC scoring or dual-scoring with IRC to ease the transition.

The move is driven by a desire for transparency, international alignment and access to the robust technical framework that ORC offers. Some Irish sailors are asking for consistency with European events where ORC is already well established.
