Power and speed
By hovering high above a ship where wind speeds are greater, the aerodynamic design can generate three times more power per square metre than a conventional sail.
But even so, to give a SkySail enough muscle to tow a tanker, the kite canopy has to be massive - about the size of a football pitch.

The kites are designed to be aerodynamic in all wind speeds.
