From Wikipedia [1]: > The ship will be equipped with five retractable, telescopic wingsails that can rotate 360 degrees. The masts will measure 80 m (260 ft) for a total height above the waterline of 45 to 105 m (148 to 344 ft). That would also make it the tallest ship in the world. The rigging will be made from steel and composite materials and resemble airplane wings. An auxiliary engine will be used to navigate harbors and provide emergency power. > While the design is meant to be usable for different types of ships, the first version is planned to be a 200 m (660 ft) long roll-on/roll-off ship with a capacity of up to 7,000 cars. Such ships will be used on transatlantic routes and are expected to perform the journey in 12 days, longer than the current average of eight. > Open-sea trials with a 7 m (23 ft) prototype were conducted in the summer of 2020 and are scheduled to continue during the fall. Commercial orders are expected to start in 2021, with an entry into service in late 2024. [1] https://en.wikipedia.org/wiki/Oceanbird https://en.wikipedia.org/wiki/Oceanbird
