Dublin Bay Sailing Club (DBSC) will include ORC handicap racing in its 2026 season. The club has amended its Notice of Race accordingly.

The revised rules state that Cruiser classes 0, 1, 2 and 3 will be scored under ECHO (progressive), IRC and ORC. ORC scoring will apply if a class requests an ORC rating before the season starts. YTC or VPRS ratings may be substituted for IRC if similarly requested, the notice says.

The change was communicated to members in a January 20th notice from DBSC. Queries are to be directed to the club’s Honorary Secretary.

DBSC is Ireland’s largest yacht racing club. Its decision follows growing interest in ORC rating across Irish cruiser fleets. Clubs have been exploring ORC alongside traditional IRC and ECHO systems. Trials at events such as Calves Week showed mixed‑fleet ORC scoring in practice, and more than 100 Irish boats appeared on provisional ORC Club ratings lists for 2025.

Supporters of ORC say the measurement‑based system offers transparent scoring and aligns Ireland with broader international practice. Critics in the sailing community continue to debate its complexity and impact compared with IRC, which has been the dominant handicap rule in Ireland.

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.
