The purpose of the World Sailing Offshore Special Regulations (referred to as OSR below) is to establish uniform minimum equipment, accommodation and training standards for monohull and multihull yachts racing offshore.

The RORC categorises its races depending on the duration, exposure of the race course, distance to the shoreline and the degree of self-sufficency required. The RORC also includes prescriptions to the OSR.

.

Inshore Events such as the RORC Easter Challenge or IRC National Championship are usually OSR Category 4 plus RORC Prescriptions.
A RORC Offshore Weekend Race is usually OSR Category 3, plus Liferafts as set out in Category 2, AIS Transponder plus RORC Prescriptions.
The Rolex Fastnet Race, Round Ireland Race, Ile de Ouessant Race and Rolex Middle Sea Race are OSR Category 2 plus RORC Prescriptions.
The Sevenstar Round Britain and Ireland Race and RORC Transatlantic Race are Category 1 plus RORC Prescriptions.

Please check the RORC's Notice of Race for the OSR Category required for the race you enter.
