Royal Yacht Squadron was accepted as Challenger in October 2024
RYS has named Ben Ainslie's Athena Racing team as their representative.
Jim Ratcliffe and Ineos have broken with Ainslie and have announced their intention to challenge separately,

2024 design rule for AC75 and AC40 Yachts
America's CUP - AC75
AC75 Version 2
WOMEN'S AND YOUTH EVENTS - AC40
AC40
2024 test and development boats
The Protocol limited the 2024 teams to one new AC75 yacht. They were allowed to test design ideas on smaller boats:
either an AC40 that they modified, or a test boat of their own design, called an LEQ12.
LEQ12
LEQ12 - less than or equal to 12 meters long.
Luna Rossa and INEOS Britannia designed and built LEQ12 boats.
These LEQ12 test boats had very different configurations from each other and from the AC40. Both teams set up their test boats to carry more crew than the AC40. The AC40 sails with a crew of 4. The Italian LEQ12 sailed with a crew of 6: 2 helms, 2 trimmers, 2 observers. The British LEQ12 also sailed with 2 helms, 2 trimmers but usually only one observer.
Modified AC40
Teams were allowed to modify one AC40 yacht to test foil wings and flaps, rudders, sail controls and other components.
Emirates Team New Zealand, Alinghi Red Bull Racing and New York Yacht Club American Magic all modified an AC40.
Since teams were obligated to provide their AC40's for the 2024 Youth and Women's AC racing, the boats must be returned to their "one design" configuration for that racing.

2024 Shared Reconaissance
Teams were not allowed "to spy" on each other. A two man "Recon Unit" was assigned to each team. Teams were obliged to announce in advance when they would be sailing, and what modifications they had made to the visible parts of their boat. The Recon Units photograph and video their assigned team and follow them on the water in a high speed chase boat.

Rules for the 2024 America's Cup
Deed of Gift
The America's Cup is governed by a 19th century document - the Deed of Gift. The first version was written in 1852 and signed in 1857. It was rewritten twice, in...
Protocol
Team New Zealand, the defender, and INEOS Britannia, the challenger of record agreed on the rules for the 2024 America's Cup, e.g. racing in AC75's with 100% "national" crews.
Racing Rules
With the high speeds of foiling boats, the Racing Rules of Sailing are modified to include different rules for mark roundings and how to offload penalties.
AC75 Class Rule
The rule specifies certain limits, e.g. length, weight, number of crew, use of stored energy and limitations on automation. Each team tries to design the fastest boat within these limits.
Technical Regulations
The Technical Regulations specifiy limits on the number of foils, rudders, masts and sails that teams may build. The "shared recon" program is also strictly described.
AC40 Class Rule
The AC40 is a strict "one design" class. Teams may modify their AC40 to test design ideas for their AC75, but they must return the boat to its class compliant state for racing.
