International Offshore Rule

The International Offshore Rule (IOR) refers to a set of regulations and guidelines that govern the construction and operation of offshore yachts, ensuring safety and performance in open water. Developed by the International Sailing Federation, the IOR measures a yacht's design, size, and weight to provide fair competition in racing. It encourages innovation while maintaining standards among different yacht types, allowing for an equitable racing experience. Essentially, the IOR helps establish a level playing field for sailors competing in offshore events, promoting fair play and safety at sea.
