ISORA (Irish Sea Offshore Racing Association) is a not-for-profit members organisation responsible for offshore racing in the Irish Sea.
The Association is run by volunteers for the benefit of competitors by working in partnership with boat owners, crew, clubs, associations, and the governing bodies for boating in Ireland, Wales, and the UK.
Our mission is to promote the sport of offshore racing in the Irish Sea.
The MUSTO ISORA 2026 Series of races comprises the traditional Offshore Series of seven offshore races, an additional two long distance races, a Coastal Series in Ireland, and a Coastal Series in Wales.
The Races are subject to change, and all competitors should check the latest published schedule of races on the ISORA.org website.
This Notice of Race (NoR) applies to all ISORA organised races and includes Rules that affect every race unless modified by the Race Specific Sailing Instruction (SSIs).
When a Rule is modified in the SSIs, it takes precedence over the Rule in this Notice of Race and General Sailing Instructions.
