Hydrofoil

Back in 2016, we heard about Dutch startup Edorado's planned electric hydrofoil, known as the 7S. Well, the company has now announced development of a bigger and better model, appropriately enough called the 8S.

Candela has applied its expertise in low-drag nautical engineering to build a bigger and better version of its hydrofoiling watercraft. Dubbed the C-8, it's claimed to have the longest range of any electric boat in history.

Batteries are taking ages to improve, but Sweden's Candela isn't waiting around. Instead, it's built a low-drag hydrofoiling boat that barely touches the water, giving it a super-smooth, efficient ride and three times the range of other electric boats.

After first appearing on our radar in late 2017, the Manta5 XE-1 Hydrofoiler has now entered production. The company has a range of water hydrofoil bikes planned, including racing versions, electric-only motorcycles for the water, and a surfing model.

Swedish boat-builder Candela is looking to make some waves in the local water transportation scene with a fancy new foiling ferry it claims will be world-beating in a number of ways, including becoming the fastest all-electric passenger ship ever made.

Technology appears to be a big topic at this year's Palm Beach boat show, so it's not too surprising to see the launch of a Silicon Valley startup there. Navier is looking to make nautical design more high-tech with a self-piloting electric hydrofoil.

Nemesis Yachts has put forward a blue-sky vision for a super-fast, hydrogen-powered, autonomous luxury catamaran that can rise out of the water on hydrofoils to achieve crazy speeds over 50 knots. Oh, and you can swap this 300-footer's cabins out.

At last year's CES in Las Vegas, Waydoo launched a relatively cheap electric foil board called the Flyer, which went on sale late in 2019. Now the company has hit Kickstarter with a cheaper follow up called the Flyer One.

After launching its first electric-powered hydrofoil board a couple of years ago, Fliteboard now hopes to further elevate the ride experience with an app that offers detailed ride-tracking and over-the-air updates to improve the board's performance.

When a team of engineers discovered a 1988 prototype of a jet fighter-styled hydrofoil out the back of a warehouse, they thought the same thing you and I would, and they couldn't resist fixing it up, putting a new motor in and taking it for a blast.

Hydrofoiling devices are starting to become more common as electric propulsion systems continue to develop. This one's a board you can stand on and accelerate up and out of the water to cruise at a low-drag 28 mph (45 km/h) for up to 80 minutes.

The 2020 Foiler flying yacht has swapped out the hybrid propulsion system of the 2019 model for two 370-hp V8 diesel engines.
