Reused hulls and systems first
The decision was made to race in Naples with hulls from the 37? America's Cup, or adapted from the 2021 AC36 models. According to architects Dan Bernasconi (Emirates Team New Zealand) and Nick Holroyd (Athena Pathway), speed analysis showed that differences due to hull shapes were minimal. The real gains are concentrated in foils, appendages and onboard systems. As a result, reusing hulls is an obvious way of reducing costs and refocusing development on critical systems.
Stored energy and the end of cyclists
A major change is the disappearance of the "cyclors", the team members who generate mechanical energy via pedals. From now on, systems will be powered by standardized batteries, defined by a one-design unit common to all teams. Electronic and hydraulic systems thus become a major field of innovation, while guaranteeing a degree of fairness between competitors.
A new crew of five with a female quota
AC75s will have to carry five sailors instead of four, including at least one woman. This structural change brings the men's and women's America's Cup programs closer together, since rotation of sailors between teams becomes inevitable. It also emphasizes collective strategy, positional navigation and tactical coordination, rather than just physical optimization.
Guest Racer on board
Another new feature, a Guest Racer seat will be integrated aboard the AC75s during the regattas. Inspired by the "18? man" concept seen in Valencia in 2007, this opening allows a guest to experience the race from the boat itself. The initiative is designed to raise the event's profile and extend the experience to the public and partners.
AC40 and preliminary races
Pending the return of the AC75s to the water in January 2026, the teams will concentrate their training on the one-design AC40s. Two boats per syndicate will be allowed in the first three preliminary regattas of 2026, one of which must feature a mixed crew of youngsters and women, in accordance with the protocol.
Technical regulations and budget limitations
The new regulations detail the tolerances:
- three foils from the previous edition can be modified by up to 20%,
- five new flaps and three new foils are authorized,
- a single new mast for teams having built only one AC75,
Strict budget restrictions reinforce the organizers' determination to contain the technological inflation that has historically characterized the event.
Towards more sustainable and open publishing
Between reused hulls, eliminated cyclors, imposed batteries and more inclusive crews, the 38? America's Cup is taking a significant turn. The aim is twofold: to guarantee tight competition on the water and maintain the event's economic and environmental sustainability, while expanding its audience.
