America’s Cup Monohull Foiling And The Transition.

58 / 100

Foiling is a technology and technique used in sailing that has gained significant attention and popularity in events like the America’s Cup. Foiling involves using hydrofoils, which are wing-like structures mounted under the hull of a boat, to lift the hull out of the water and reduce drag. This allows the boat to achieve higher speeds and improved performance.

In the context of the America’s Cup, foiling has revolutionized the sport. The America’s Cup is one of the oldest and most prestigious sailing competitions in the world, dating back to 1851. Traditionally, America’s Cup boats were monohulls with a single, deep keel that kept the boat stable in the water. However, in recent years, the America’s Cup has transitioned to foiling multihulls as seen in San Francisco { AC72}  and the AC50’s in a world curcuit sailgp and the new monohull boats, often called “AC75s.”

The move to foiling boats in the America’s Cup has led to faster, more exciting racing. The AC75s use large hydrofoils on each side of the hull, which lift the boat out of the water, reducing drag and allowing the boat to reach incredibly high speeds, sometimes exceeding 50 knots (over 90 kilometers per hour). The combination of cutting-edge technology, skilled sailing, and high speeds has made the America’s Cup even more thrilling to watch.
