Which is faster AC75 or AC72?

The 23-foot foiling monohull is a mini-version of the much larger and faster 75-ft. AC75. This year’s AC72 will be an entirely different design, based on a 75-foot, carbon-fiber monohull that lifts out of the water on two foils. It will have a crew of 11 and will have a top speed of about 63 mph.

How does the AC75 work?

With the AC75 sailing on its foil, drag is dramatically reduced, vast amounts of power can be generated and so speeds rapidly increase. There is another positive to this: as the lifting foil is angled, it produces lift to windward, which can force the boat more towards the wind than the angle it is sailing.

How fast can an AC75 go?

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.

What was the purpose of the AC72 class?

At the same time a smaller sister class, the AC45, was developed to allow teams to practice and adjust to the new formula as well as create a greater exposure of sailing to the general public with the America’s Cup World Series . The AC72 has the following maximum specifications:

Is the foiling 600 hull made of carbon fiber?

The beauty of the foiling 600 is it was designed so you could convert an existing 600 hull – ideal as a lot of boats came on the market when the newer, spinnaker-carrying RS700 was introduced. Linton went on to develop a specifically-designed carbon fiber hull for added responsiveness.

Why was foiling added to the America’s Cup?

“Eventually we put all that technology and testing into use on our SL33 catamaran and, ultimately, we built our AC72 catamaran with fully foiling in mind. We knew we could do it, and we knew we had to push hard and push big because absolutely we could see that foiling was the future.”

How did the AC72 sail in the America’s Cup?

The AC72 has the following maximum specifications: Using foils for the first time in the America’s Cup the AC72 was expected to sail faster than the wind: upwind at 1.2 times the speed of the true wind, and downwind at 1.6 times the speed of the true wind.
