Sweden-based company Candela has unveiled the first-ever electric-powered speedboat that can reduce seasickness, a type of motion sickness characterized by dizziness and nausea experienced when riding a watercraft.

The speedboat, called the Candela Seven, uses hydrofoil technology that enables it to skip over waves instead of slamming against them. According to its developers, the boat’s hydrofoils decrease the friction of the water and the impact of waves hitting on its hull. It also has a built-in computer system that automatically controls and adjusts the foils’ position to reduce the swaying and rocking of the boat.

Because the speedboat’s technology prevents it from being hit by waves, its passengers are likely to have a smooth ride, which may reduce their risk of seasickness.

As it is made almost completely from carbon fiber, the Candela Seven is eco-friendly. It has an electric engine that reduces carbon emissions by 99% and generates less noise than other commercially available electric boats. The developers said that it takes just 1.5 hours to fully charge the battery of the boat using a special charger or 12 hours using a regular one.

The speedboat costs €250,000 (about ¥31 million). Its developers expect that it will appeal to wealthy residents of lakeside cities. The Candela Seven has the capacity to carry a driver and up to five passengers, and it is capable of reaching speeds of up to 55 kilometers per hour. According to the developers, it can be used for day trips or sailing across lakes.
