Structure
Current kite rigs can be sailed within 50 degrees of the wind.[1] This allows them to sail upwind by tacking.
A power kite is held at an angle to the wind using control lines. Like any other sail, the kite develops lift and drag, pulling the vessel. The vector of the kite's pull is added to the forces[disambiguation needed] produced by the vessel (water resistance against the hull, force of wheels against the ground, etc.) to move the vessel in the desired direction.
Windspeed
Kites may be adjusted with respect to the wind, manually or by an automated system. A kite cannot stay aloft when there is no wind, and must be re-launched.

Solo sports
Kite rigs power a variety of recreational conveyances on water and land. On water, kites are used to power
Ships
Ship-pulling kites run to hundreds of square meters of area and require a special attachment points, a launch and recovery system, and fly-by-wire controls.
The SkySails propulsion system consists of a large foil kite, an electronic control system for the kite, and an automatic system to retract the kite.

The kite is launched and recovered by an animated mast or arm, which grips the kite by its leading edge. The mast also inflates and deflates the kite. When not in use, mast and deflated kite fold away.[3]
Use
A commercial cargo ship, the
Maartje Theadora, a large fishing trawler, was retrofitted with a kite rig in 2010.[7]
