Are the new Americas Cup boats faster?
The current design will achieve speeds approximately four times faster than boats racing in the America’s Cup 10 years ago. The main reason for this increase is that Cup teams now race catamarans, rather than the monohulls used in the past.
What does AC75 stand for?
The AC75 (America’s Cup 75) is a racing yacht used in the 2021 America’s Cup match and planned to be used for the 37th America’s Cup and 38th America’s Cup matches.
What do grinders do on America’s Cup boats AC75?
A grinder is a crew member on a yacht whose duties include operating manual winches (called “coffee grinders”) that raise and trim the sails and move the boom. It is a physically demanding role with a significant impact on a racing yacht’s overall performance.
Who has the fastest AC75?
Speeds. Potential speed of 50 kn (93 km/h; 58 mph) was claimed based on computer simulations. Notable high speeds actually recorded in racing were: 49.1 kn (90.9 km/h; 56.5 mph) by Te Rehutai (in 15 and 19 kn (28 and 35 km/h; 17 and 22 mph)) on 17 December 2020.
How fast do the Prada Cup boats go?
The 75 foot (22.86m) keel-less yachts rise out of the water on hydrofoils and glide across the surface to reach speeds in excess of 50 knots (93 kilometres per hour).
Who invented the AC75?
builder Manoel Chaves
When the concept for the AC75 was revealed on November 21, 2017, Brazilian naval engineer and boat builder Manoel Chaves believed his patented Sailing Booster System, which resembled the canting foil system on the America’s Cup boat, had been infringed and has hired legal support to pursue a settlement.
What is a new America’s Cup boat?
A new America’s Cup boat is a vastly complex bit of kit. Each team has incredibly powerful Computational Fluid Dynamics (CFD) software packages and simulators in order to try to understand the various gains and losses.
Is this the most radical America’s Cup boat ever?
The AC75s, the America’s Cup boats currently racing in the Prada Cup and that will be used for next month’s Cup match showdown, are arguably the most radical boat the America’s Cup has ever seen.

What makes the America’s Cup foils more efficient?
With foiling now established for the America’s Cup, a key focus for designers has been to make the foils more efficient. Once again designing the shape, width and thickness of the foil wing is a trade-off between speed and stability.
