America's Cup - AC 40

The racing yacht AC40 - flying over the water with foils - speed over 45 knots

The AC40 racing yacht embodies the latest generation of state-of-the-art sailing technology and is a pinnacle in the development of performance sailing yachts. The boat, its controls, sails, foils and mechanisms are all standardized so there is a strong focus on racing craft, positioning and foils technique to "fly over the water". On the water, each team consists of just four sailors with two oars steering from the front “pod” and two crew members responsible for sails and foils trim sitting in the rear pods. The race promises to be fast and furious as the AC40 can reach speeds of over 45 knots downwind and high 30 knots upwind.
The AC40s are the boats used for the Youth and Women's America's Cup events, as well as as training boats for the teams competing in the 37th Louis Vuitton America's Cup (AC75). Smaller but no less powerful, with a crew of four, these "racing yachts" were launched to great fanfare in September 2022 and their performance was astonishing.

Foils act as wings

The foils act as wings and provide buoyancy, allowing the boat to float above the water. Thanks to the low friction loss, the racing yacht can reach speeds of up to 80 km/h. The AC40s are built at McConaghy's state-of-the-art manufacturing facility in New Zealand on a 7-axis CNC machine.

Optimal speeds are the #1 success factor

Optimal speeds are the decisive factors for the success of the team, the harmonious flow of movements during maneuvers on board and the optimal physical speed of the boat against and in front of the wind. The four-person team has a lot to train in order to move optimally on board, operate the foils and steer the optimal course up and downwind. Because just a few degrees of steering make a big difference, see the polar diagrams of the AC40.
The "Performance data (1)" from Emirate Team New Zealand shows the speed potential of an AC40 at the following wind speeds (knots-kts, true wind speed TWS):

  • TWS   8 kts, Boat Speed 26 kts at 46° Upwind course, Speed 30 kts at 138° Downwind course,
  • TWS 12 kts, Boat Speed 31 kts at 41° Upwind course, Speed 38 kts at 145° Downwind course,
  • TWS 20 kts, Boat Speed 39 kts at 41° Upwind course, Speed 44 kts at 155° Downwind course.

(1) The performance data is estimated; the AC40 teams have to specifically test the properties of their AC40 during training.

US Challenger "American Magic" marked max speed: 49.83 knots

US Challenger "American Magic" marked 100 days of sailing in their AC40 America with the release of some key statistics including an impressive to speed. The top speed released was less than 0.2kts off the magical 50kts mark. Performance statistics:
Max speed: 49.83 knots
Anderson Reggio, American Magic's performance analyst, sheds light on two-boat testing's value as the team enters the third week of testing both AC40s side by side in Barcelona, gearing up for the 2024 America's Cup.

Emirates "Team NZL" keeps up speed testing

Emirates "Team New Zealand" sailed twice - once with the Youth/Women's crew in the AC40-OD and on Wednesday with the LEQ12 and AC40 working through a racing/speed session.

AC40 simulator - Emirates Team New Zealand

While the America's Cup teams use their AC40s for testing, development, match racing training and other events, they will be used for both the Women's and Youth America's Cups as an important tool in establishing entry into the America's Cup. Cup for women and the next generation of “foils sailors”. This journey was made all the easier with the added benefit of the availability of the AC40 simulator, developed by Emirates Team New Zealand for pre-delivery training.


Abby Ehler: "Tactical Sailing - What a great tool for teaching"

Abby Ehler had the opportunity to trial and test the TacticalSailing software at the boot Düsseldorf. "What a great tool for teaching youngsters, professionals and oldies alike, to visualise what happens out on our 'playground' the shifts, gain & loss, and pressure." Get the simulations in the Coach's Toolbox here. Paul Gerbecks who has masterminded this software is extremely passionate about the benefits this can offer to up and coming sailors in addition to their on water training. See more info from Abby Ehler on facebook. For example, Abby also sailed in the SCA - Volvo Ocean Race team.
