Current Class Rules
The class rules comprise the official Class Rules document, as well as the current Building Specification. The Class Technical Committee maintains a Frequently Asked Questions (FAQ) document, which provides interpretations, explanations, and clarifications of the rules where needed. The J/70 Class organization operates according to the Class Constitution. All of these documents are linked below in PDF format.
Technical Bulletins & Reports

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.
