The largest sailing cargo ship in existence is on its maiden voyage across the Atlantic Ocean, demonstrating a carbon footprint 10 times smaller than that of a container ship
As a result, I guess that rotating masts aren’t optimal after all - too much moving mass, impossible to take down during a hurricane, etc.
Rotating masts are for ships that are larger, and they only contribute to propulsion, saving up to 30% of fuel. But they work well in almost any wind direction.
This ship is primarily driven by the sails, if conditions are good.
It’s different technology for different tasks.
I also guess that this sailboat has a fairly good motor, for use during total lack of wind (rare) or storms that would damage sails or masts.
It has a 5500 horsepower Diesel-eletric motor. “For maneuvering in harbor and punctuality of service” according to the manufacturer.
