photo - cargo ship - with Wingsails, analogous to aeroplane wings, provide lift on either side.

photo - cargo ship - with Flettner rotors are smooth cylinders with discs that spin as wind passes at right angles across it.

graphic - Ship performance polar diagrams for the Flettner rotor-assisted Panamax bulk carrier for varying true wind at a constant ship speed of 12 knots. The polar diagram shows the fuel consumption (FC), in kg per hour, of the Panamax bulk carrier ship with four Flettner rotors at different true wind angles (TWA) and wind speeds.

maps and graphs - The optimised routes, wind rose plots and wind speed histograms for three example routes in the Atlantic Ocean. a) Set of optimised shipping routes, the wind speed and direction profiles for the great circle route and optimised voyages, and the wind speed histogram distribution for all journeys across four years between Montevideo (Uruguay) and South Africa. b) The same data for all journeys between Plymouth (UK) and Norfolk (USA). c) The same data for all journeys across four years between the Panama Canal Pass and Gibraltar.
