EVERY RIDE, IN ONE PLACE Where you rode, how long, the conditions, the gear, who was with you. Your logbook builds itself. A LOGBOOK THAT MEANS SOMETHING Anyone can claim hours. When you ride with an accredited operator or one of its instructors, they can confirm the sessions they ran — which is what an operator looks for before renting you a board unsupervised. FIND SOMEWHERE TO RIDE Search the directory of eFoil operators — schools, rental centres and guided riding — plus shops and instructors, and see them on the map. Any eFoil business can apply to be listed. YOUR QUIVER, TRACKED Boards, masts, wings, batteries. Set a preferred setup and take it with you wherever you ride. BUILT ON A WRITTEN STANDARD EASI publishes a safety and training standard and accredits operator businesses against it. Rider and instructor levels are assessed and awarded by those operators; EASI records them. EASI does not train, examine or assess any individual. EASI is a private, voluntary industry scheme. It is not accredited by, or affiliated with, the United Kingdom Accreditation Service (UKAS), holds no recognition under retained Regulation (EC) 765/2008, and is not a national accreditation body. EASI accreditation applies to operator businesses only and carries no government or UKAS status.
