Kiteboarding - Wikipedia
https://en.wikipedia.org/wiki/Kiteboarding

Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, or snow surface. It combines aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less

History

Late 20th century
In October 1977 Gijsbertus Adrianus Panhuise (Netherlands) received the first patent for KiteSurfing. The patent covers, specifically, a water sport using a floating board of a surf board type

Environments

Kitesurfing on water includes freestyle and big air using a kiteboard similar to a wakeboard, kiting in waves using small surfboards with or without footstraps or bindings, foiling, and

Governance

International kiteboarding has several promoting organizations and has undergone many changes in the governance of the sport, including long-lasting disputes between several of those entities, trying to negate each other the right to promote such

Techniques

Kiteboarding can pose hazards to surfers, beachgoers, bystanders and others on the water. Many problems and dangers that may be encountered while learning kiting can be avoided or minimized by taking professional instruction through lesson centers. Kitesurfing

It gets the wind-catching gizmo up to an altitude where winds are more
reliable than near ground level. If you could tap the more-or-less permanent cyclone
around the South Pole, that'd be really something.

Because it's a circular wind, any energy you miss on pass 1, is still there on the next
cycle...

A kite surfer is pulled by the kite. A diesel power ship is only
assisted. If the ship is powered at 15 knots, and the wind is 15 knots
from, sheer luck, dead astern, the kite falls into the water.

Windmills are stationary, so any wind is relative wind.

exactly,
so kites for diesel ships are designed as rigid structures,
and nothing falls into the water if no wind at all

Nevertheless, kite for diesel ship is an old fake

I recall experiments with vertical fixed sails, installed on top of diesel ships.

But not aware of any success story
