Racing and Event Regulations
In order to standardize the equipment inspection and on-water racing experience in J/70s and to better support regatta Organizing Authorities, the Class publishes official Equipment Regulations (covering how boats and sails are inspected at events) and Regatta Regulations (covering how race committees run the sailing events). Note that the Notice of Race for most Class-Sponsored events will incorporate the Equipment Regulations and Regatta Regulations as rules. The Organizing Authority Guidelines are intended to assist in the planning for Class-sponsored events.
