America's Cup: Thanks to groundbreaking technology, the wind is visualized live on the screen. This allows fans, commentators and coaches to better understand the team's routes and tactics and makes coverage of the sport more accessible than ever before.
WindSight IQ: The technology used is a "wind view" using "LiDAR" (Light Detection and Ranging), sensor fusion and scientific calculations to display the wind in augmented reality (AR) and virtual reality (VR) graphics.
On the water, in strong winds of 4 Bft and above, "waves" or "white caps" always appear on the water surface.
Wind gusts: In light winds of 1-3 Bft, you can see alternating so-called wind gusts, which are light and dark "spots" distributed on the water surface. Depending on the wind strength, the water surface ripples there or is "smooth". The borders of these spots are quite bizarre - "frayed" - depending on the "light incidence" from sunlight and cloud shadows - no sharp borders or edges, not straight.

Tactical Sailing simulates the wind on the screen in various formats in the Coach's Toolbox, for better understanding in simplified form as an ellipse or circle. Each format has its own wind, which can change in wind strength and direction at the edges in a transition zone.
The wind gusts move across the regatta field in the form of circles and ellipses, they offer ideal opportunities for learning and practicing the optimal routes and tactical maneuvers. Wind direction and strength can be changed by the trainer.

The foils act as wings and provide the lift, allowing the boat to float above the water. The AC75 is large - 75-feet  (22,86 m) long and 16-feet (5 m) wide - but, it's also light, which is crucial, because the AC75 is designed to fly.
It's also different - rather than a keel, a brand new concept keeps it standing. "Foil Cant Arms" move under, or outside, the boat to provide the leverage it needs to stay upright.

Some parts of the boat are supplied - the mast, rigging, foil-cant arms and their hydraulics are all stock components. But, there are still plenty of areas that designers can experiment with to find a race-winning edge.
The double-sail skin Mainsail combines with the "D" shaped mast to form a wing, generating the power (upper- and lower preasure) the AC75 needs to foil.
Underwater is where things get really interesting, the foil cant system is a battery-driven, hydraulic power-unit that supplies the energy to lift and lower the immensely strong - and heavy - foil cant arms.

As the boat swaps tacks, the cant system is activated, placing one hydrofoil in the water, and lifting the other one out, where its weight becomes ballast.
At the end of the arms lie the teams' secret weapons - the foil wings.

Sir Ben Ainslie was a guest at the "boot" trade fair in Düsseldorf, where Tactical Sailing had the opportunity to talk to Ben about "A Game Against the Wind." With his autograph on the CD he expressed his good wishes for success at the trade fair! INEOS Britannia is a British sailing team that is the record challenger for the 37th America's Cup. The team was formed in 2012 with the aim of winning the America's Cup for Great Britain and "bringing the trophy home to the United Kingdom". The team merged with INEOS in 2018. In 2021, the team competed as representatives of the Royal Yacht Squadron for the 36th America's Cup in Auckland, New Zealand, but without success. The team is owned and supported by INEOS founder and chairman Sir Jim Ratcliffe and is led by the most successful Olympic sailor of all time, Sir Ben Ainslie, who is team principal, CEO and skipper.
On October 4, 2021, the team announced a high-performance partnership with Mercedes-AMG F1 Applied Science, a division of the Mercedes-AMG Petronas F1 Team that brings together the best from the world of high-performance marine and automotive engineering. The aim is to win in 2024 the 37th America's Cup for Great Britain.

Based on computer simulations, a potential speed of 50 kn (93 km/h; 58 mph) was given.
Notable high speeds actually recorded in racing were:
- 49.1 kn (90.9 km/h; 56.5 mph) from Te Rehutai (in 15 and 19 kn (28 and 35 km/h; 17 and 22 mph)) on 17 December 2020.
- 50.25 kn (93.06 km/h; 57.83 mph) from Britannia on day four of the Prada Cup, January 23, 2021.
- 53.31 kn (98.73 km/h; 61.35 mph) by Patriot (American Magic) on day one of the Prada Cup semi-finals (in a breeze of up to 22 kn (41 km/h; 25 mph )) on January 29, 2021.
The AC75's takeoff speed is 13 knots (estimated) and 50 degrees TWA (True Wind Angle).
