Take pleasure in some bushy onboard footage as this alien spaceship of a sailboat data the second-fastest velocity in historical past. The outright document is now nicely inside attain, and this outrageous kite-powered boat is designed to utterly smash it.
You would possibly count on the world’s quickest sailboat to levitate out of the water on a low-drag hydrofoil – however no. Swiss team SP80 has chosen a super-lightweight trimaran hull design, 10 m (33 ft) lengthy and seven m (23 ft) vast, that’ll keep involved with the water. Hydrofoils, in keeping with the workforce, aren’t appropriate for this gig, for the reason that low-pressure zone brought on by these underwater wings causes water to boil into vapor at excessive speeds in a course of referred to as cavitation, inflicting harmful ranges of drag and instability at speeds over about 60 mph (~100 km/h).
It seems extra like some form of futuristic plane than a sailboat – there is not any mast, for starters. As a substitute, there is a large parachute of a kite, connected by way of cables to a wing-like management arm hanging low off the left aspect of the boat. Therefore the width of this beast – that kite is designed to drag exhausting from one aspect, and the remainder of the boat is designed to show that pull into most ahead velocity whereas resisting rollover.
SP80 PRESENTS: THE BOAT DESIGNED TO BREAK THE WORLD SAILING SPEED RECORD
It additionally wants to withstand the kite’s tendency to drag the boat up and out of the water, so on the precise aspect there is a foil blade designed to drag downward and to the precise because the velocity comes up. Managing the kite might be a full-time job on excessive velocity runs, so the SP80 seats two pilots. One in entrance to steer the boat, the opposite sitting behind in a tandem formation to function the kite-sail.
The outright world velocity crusing document nonetheless stands at 65.37 knots (75.23 mph, or 121.06 km/h) and was set some 13 years in the past by Paul Larsen in the Vestas Sailrocket 2. However that is not workforce SP80’s goal – these guys reckon their kite-powered trimaran is sweet for north of 80 knots (about 92 mph, or 150 km/h).
After a number of years of improvement and testing work, the SP80 is beginning to stretch its legs, and the workforce has simply introduced the second-fastest velocity in crusing historical past: 58.261 knots (67.1 mph, or 108 km/h). It would not sound like a complete lot; a typical Sea-Doo RXP-X 325 RS jet ski would nonetheless stroll away from it. But it surely’s a few knots sooner than any America’s cup yacht has managed, and the view from the cabin seems and sounds sketchy as hell:
“It is a main milestone for all the workforce,” mentioned Mayeul van den Broek, SP80 pilot, in a press launch. “Only a few sailboats in historical past have damaged the 100-km/h barrier, and weʼre now tangibly closing in on our final objective. Whatʼs particularly encouraging is with the ability to repeat these speeds a number of occasions all through the week. It confirms not solely the boatʼs reliability, but additionally its capability to go even sooner. From right here, the work continues: analyzing the information on land, and refining our dealing with on the water as quickly because the wind permits.”
There’s work to do but; the SP80 did certainly break 100 km/h – however solely momentarily. Larsen’s official document was a mean velocity over 500 m (1,640 ft), as are most World Crusing Pace File Council certifications. In these phrases the SP80’s finest go thus far was simply 48.645 knots (56 mph, or 90 km/h).

However the workforce will proceed testing over the following month, off the coast of Leucate and Port-La Nouvelle in southern France, and there is each probability they will lastly relieve Larsen of his document.
By the way, once we first began following this undertaking, there was an much more weird kite-powered design racing towards it. The Syroco Speedcraft, from France, proposed a “weightless boat” dangling in mid-air, pulled upward by the kite, and anchored within the water by a hydrofoil pulling downward. Take a look at the prototype in flight:

Bonkers, proper? Sadly, that video was launched on the finish of 2022, and that is about the place the path goes chilly. So we might like to know what workforce Syroco is as much as – it is very cool watching the SP80 shut in on the world document, but it surely’d be much more enjoyable with some competitors respiratory down its neck!
