The World Sailing (WS) Offshore Special Regulations (OSR) governing Offshore Racing for Monohulls (Mo) and Multihulls (Mu) are the internationally accepted minimum equipment, accommodation and training standards for monohull and multihull yachts racing offshore. Developed by experienced racing sailors over time, they are designed to supplement the requirements of governmental authority, the Racing Rules of Sailing and the rules of Class Associations and Rating Systems.
World Sailing and Sail Canada (SC) strongly recommend the use of these Special Regulations by all organizers of offshore races. Race Committees may select the category deemed most suitable for the type of race to be sailed in accordance with the definitions in section 2.
World Sailing Offshore Special Regulations are reviewed continuously and are published every two years by the WS Special Regulations sub-Committee. (Chaired by Will Apold (NS))
Sail Canada’s Offshore Group prescribe amendments to the Special Regulations to take into account Canadian legislation and practice. The World Sailing Offshore Special Regulations can be found at:
