Here I sail one of my wings on ice. It hangs on the shoulders and I wear ice skates.
Wind is very light, you can hardly feel it in your face, still speed is some 40 km/h, 25 MPH, or some 6 times faster than the wind. In strong wind, at top speed, it sails 4 times faster than the wind.
Frontal view. An Ice Wing cockpit is cramped. Generally a thinner wing is faster.
Sail on ice, snow and land. Water?

My fastest Skate Sail Concept
The sailor supports himself on one leg in the lower wing. His body is horizontal in the streamlining. The other leg is horizontally backwards in the streamlining. This way the sailor's body resistance is minimized.
This is the fastest skate sailing concept I can come up with. Fastest because its sail area can be made very small.
Sailing video. Very light wind 4 knots, 2 m/s, note flag movements. Still speed is 25 mph, 12m/s, 40 km/t - 6 times faster than the wind! Filmed by skating, panting, person. Note plenty of text with the video. (Video is short: Having breakfast, drive to lake, rigging, waiting for wind, etc. has been cut out. :) )
A wing sailor sailing at top speed in a strong wind. He leans to windward to balance the force of the wind. Speed is some 120 km/h, 75 mph.
Ice-Wing Cabriolet, has good performance for its size because the sailor makes no air resistance.
Rolls into a tubular pack for storage, or transport on the ice when there is no wind.

is an incredible performance for its size and simplicity. With no
restrictions to the design, it is probably the most challenging ice
sailing class to design, build and sail.
has not yet really been tried on land, with roller skates, on skate
board or on a bicycle. Will you be first to beat the land yachts? Using it on water is also a possibility.
This is wing sailing in its most refined form!
It consists only of the bare minimum for sailing - a sail. No: hull, mast, steering and sheeting arrangements....
It is as fast as an ice boat. One can suggest that the ice boats are heavily over-engineered for achieving the same speed performance.
“Simplicity is a great virtue but it requires hard work to achieve it
and education to appreciate it.
And to make matters worse: complexity
― Edsger W. Dijkstra
speed performance, even in strong winds, is the same as for big ice
boats, like e.g. the E-Skeeter, it sails 4 times faster than the wind.
One can say the ice boats are "a bit over-engineered" to achieve the
same performance as they apart from the sail has a plank, to give them
width and stability, a hull to give them length plus more extras as
cockpit, steering and sheeting arrangements.
They have a much higher
driving force but it is eaten away by the aerodynamic drag mainly of
hull, plank and sailor, if he is not under a canopy. Also reducing speed is the larger friction of the runners due to
the much larger weight of the craft.
to the land sail speed record holder Greenbird (2009) and, other
ice/land/snow sailing concepts, America's Cup 2013 boats etc, this
- Has no aerodynamic drag from hulls/planks/stays/sailor/cockpit/wheels/runners etc. The only aerodynamic drag is from the wing which is unavoidable.
Greenbird wing alone has the ability to sail some 60 times faster than
the wind. That means it has e.g. 10 pounds of drag when creating 600
pounds of force. But when all the other drags are added it can sail only
some four times faster than the wind. That is the same figure as for
the Stand-Inside wing sail at high speeds. For Greenbird the other drags
amount to some 140 pounds! With a [stand inside] wing only you get rid
of most of these - except wheel, runner, ski or surfboard drag.
when it comes to the drag of the sailing surface it is minimum when
sailed on ice. Wheels, hydrofoils, boards, hulls etc. create much larger
- A wing skate sailor normally supports his weight on one skate
only. To sail a desired course and steer the sailor trims the wing
backwards/forward until in equilibrium. This eliminates the drag of an
unbalanced craft. The Greenbird yacht e.g. most probably creates drag
because the sail force tries to make the yacht 'bear away' or 'head up
wind' which has to be resisted with steering which causes drag.
travel in a state between flying and falling. Sailing on one skate,
leaning into a wind which every little change is transmitted directly to
your body. The only sound is the faint whistle of the wind outside your
wing." That is skate sailing according to one of the addicts.
More about Wing skate sailing
Extremely tall sailing skates, 1 feet, 30 cm. The
height can be changed by replacing the read tubes with others of
different length. Light wind and good ice: With high skates you can
carry a tall sail with large area = a fast sail. Strong wind: Low skates
and a lower small sail.
It is by far not the tallest skates. A
friend of mine made skates 3 ft, 1 m, tall. He sat on the ice strapping
them on. A couple of friends than raised him to the vertical position.
He skated a bit then asked to be lowered down on the ice again....
I wasn't present so I have no photo.
After the wing skate sail? Twice as fast?
Stand inside wings on water
inside wing sails can most probably also sail fast on water, e.g. on a
surf board, - but there are some safety issues for the sailor to solve.
If he crashes, and especially if he gets unconscious, there is a
creative thinking needed here! A breathing apparatus securely fastened
to the sailors mouth and nose? Plus a rescue crew. Sail areas of record
wind surfers are around 55 sq ft, 5 sq m, same as a standard wing skate
A large Only-Wing sailing craft
can envision a large wing, say 30 ft, 10 m, tall. Base 10 ft, 3 m.
Ballasted at some half height. Wheels or runners, at front and back.
Some wheeled side supports for parking and take off. Can take some time
to learn to control.
to something like the record land yacht Greenbird you will save maybe
50 % on hull, plank, cockpit, wheel fairings, very strong stiff
construction in hull and lower wing to support wing's side force.

Ansar 2. Starboard tack.
This model is designed
for reading from the windward side of the boat, in at least the sector
20 to 55 degrees from the boat's center-line. Usually 10 to 65 degrees. Lines going through white clam cleats are setting the Round Markers.
The position of the central pointer gives you the wind shift information At-A-Glance!
