An early (1984) experimental kite rig being used to pull a boat. Kiteboating , kite boating or kitesailing is the act of using a kite rig as a power source to propel a boat . Kiteboating is a type of surface water sport , but it also has transportation uses [ 1 ]
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, while 1–2 orders of magnitude larger, bears similarities to the arc kites used in kitesurfing. However, the kite is an inflatable rather than a ram-air kite.
The boat has a draft of 3.00 ft (0.91 m) with the centerboard extended and 5 in (13 cm) with it retracted, allowing beaching or ground transportation on a trailer. [1] [3] For sailing the design is equipped with boom vang and a center-boom-mounted mainsheet. [1] [3] The design has a hull speed of 4.43 kn (8.20 km/h). [3]
A glass-bottom boat is a boat with sections of glass, panoramic bottom glass or other suitable transparent material, below the waterline allowing passengers to observe the underwater environment from within the boat.
The kite is fairly easy to keep flying during a fall, with 'Hindenburgs' being rather exceptional. The rider can be pulled out of the water by the force of the moving kite. The kite power can be regulated by changing the angle of attack of the kite. In light winds the kite may fall into the water and stay there.
A group has developed an air kite that dynamically was coupled with a water kite that they also developed: French L'aile d'eau L'aile d'eau (mastless boat is a water kite or paravane) The group succeeded in having a double-kite system with one kite an air kite and the other kite a paravane water kite. The air kite dragged the submarine water ...
The lift generated by the kite and other flying characteristics are affected by the kite's angle of attack, which is set by the bridle; the arrangement of lines which terminate the main kite lines and attach to a number of points across the kite's surface. Power kites having 4 or 5 lines come in two variants, fixed bridle and depowerable.
To address the poor flight characteristics of most tubes and to target thrill seekers, tubes specially designed for kite tubing have been introduced. These tubes may feature channels to allow air to flow through the tube's body, a transparent "window" for the rider to signal the boat operator, as well as more streamlined, aerodynamic designs.
