Boat of the Week: Meet the ‘Patriot,’ the New Lightning-Fast America’s Cup Foiling Yacht Representing the US

“We went off the dock thinking that if the breeze filled in, we’d have a good sail,” Terry Hutchinson, skipper and executive director of American Magic, said after the sail. “Straight away, we came into 21 knots [of wind pressure], and we were into it. Despite having a brand-new boat that we were all excited about, the whole session felt normal. That’s a great validation of our shore team and all of the work put in since we launched the Mule in 2018.”

The 75-footer is clearly fast, even out of the box, and for the next three months, designers and specialists will tweak the carbon-fiber hull and 1560-square-foot mainsail to make it even faster.

The world’s foremost sailing event, the America’s Cup has been around since 1851, though the last three Cups were more like Formula One racing, compared to the stately, slow-sailing monohulls of previous generations. The last three Cups have all been designed around foils, starting in 2013 with the AC72, and then three years ago, the boats became smaller, and much more nimble, 50-ft. catamarans that not only accelerated like an F-22 Raptor, but could nearly pivot on their own axis.

The idea was to level the playing field. Organizers supply some parts of the boat, including the mast, rigging, foil-cant arms and hydraulics. The boats—16 feet wide with a crew of 11—are also built of lightweight composites because they’re designed to fly, rather than plough through the water.” data-reactid=”28″>The last-generation cats were a bit too wild, so the powers that be came up with the current AC-72 class using a one-design rule where all competitors had to use common parts.

Another new evolution for this America’s Cup is the twin-skin mainsail on the 87-foot-tall mast. The double-sail skins combine with the spar to generate the power the AC75 needs to foil. On the last two generations, the sails were much stiffer sail-wings that many non-Cup racers complained about because there was no trickle-down technology for the rest of the sailing world.” data-reactid=”29″>Patriot’s foil-cant arms are also designed to move both under or outside the boat to provide the leverage to keep it upright.

The foil-cant system uses new technology that employs a battery-driven, hydraulic-power unit to raise and lower the strong, but very heavy, foil-cant arms, that give the boat its stability and speed. As the boat changes tacks, the cant system is activated, placing one hydrofoil in the water, and lifting the other one out, where its weight becomes ballast.” data-reactid=”30″>Beneath the water, Patriot also has an interesting breakthrough design.

Botin said this initial “analysis” phase will be critical to future modifications to the design. “We are all interested in knowing how the boat performs compared to our predictions and compared to our previous boat,” he says.

Helmsman Dean Barker described the boat’s performance as “lively.”
