Flettner rotors to help propel ships is nothing new but have got a renaissance in the last decade or so. It is not intended as sole power source, but to reduce fuel consumption and emission.
Here is an article about maybe the most well known ship with Flettner rotors, the E-ship 1:
Not Rotor sails but MOL is building a Bulk carrier with a retractable sail:
Anybody care to comment on the view from the bridge when the sail is up?
Original Fletcher Rotor fitted on a ship:
Looks like Rotor Sail may become more common, even on large vessels (VLCC and VLOC):
A regular on the Norwegian West Coast, the SC Connector belonging to SeaTrans has become the largest sailing ship owned in Norway (Malta flag):
She docked in Odda as the first Norwegian port since the conversion this Friday, but is expected to be seen regularly in the future
Shown here in the original configuration and new (in animation):
She is not a newbuilding, but a 24 year old ship that has been refitted to save fuel and the environment:
Maersk sells first product tanker fitted with Rotor sail:
Maersk Tankers has announced that it has sold 2008-built product tanker , the world’s first product tanker to test the use of wind propulsion technology. Rotor sails were installed onboard the vessel in 2018 and the company claimed that it...

She is now Indonesian.
Futuristic ship design with rotor sails:
Groot Ship Design is contracted by Neptune Marine Projects to further develop this design in a realistic vessel. We are working already for some time in close cooperation with the client and all specialists involved. Happy to report we are well on track and documentation for the first building blocks was supplied end of last year. We can’t wait to see this vessel build and completed, empowering the wings and set sail.
But what will this ship be carrying??
Here is the answer:
More Rotor Sail news:
Looks kind of funny though:
Saw the (ex) Maersk Pelican now Timberwolf, off Sydney Australia about six months ogo, hull is still Maersk blue.
What if the wind isn’t blowing the correct direction?
The Rotors are motor driven. If conditions aren’t suitable they can be turned off.
Rotor Sail Explained
With the risk of inconvenience a few forum members.
Airbus is renewing it’s fleet of roro vessels: (In anticipation of taking more business from Boing?)
Airbus has selected the French shipowner Louis Dreyfus Armateurs to modernize its entire fleet of chartered vessels that transport aircraft subassemblies between production facilities in Europe and the United States.
Each new transatlantic vessel will have the capacity to transport around seventy 40-foot containers and six single-aisle aircraft subassembly sets, a substantial increase from current cargo ships.
The nerd in me has to ask… for a US flagged rotor sail vessel, you’d have to have a sail/auxiliary sail endorsement on your license too right?
@jdcavo - thoughts?
Tongue and cheek question so here’s a response in kind. Since the rotors are purely mechanical components and require no special skills to operate, they belong to the engineering dept. Those idlers already know how to turn switches on and off and they’re always looking for excuses to hang out on the bridge anyway so I say let them fiddle with the rotors.
Actually I was serious. I can just see some overzealous LTJG MSO inspector get a burr up their ass if there’s nothing to guide them otherwise. (I’m lookin’ at you Sector Guam.)
So if these are going to not be considered “auxiliary sails,” then somebody needs to make that clear in the regs.
