Screensailing - riding with a round sail.

SCREENSAILING.
THERE IS A HIGH CHANCE THAT SCREENSAILING WILL BE THE MOST POPULAR SPORT IN THE NEAR FUTURE.

For millions of years, organisms have been selected under the harshest conditions, requiring the strictest conservation of resources. As a result, the notorious Gobsek is a terrible spender compared to our bodies. Give a man a piece of bread and he will walk a hundred kilometers. No car can travel that distance on a crust of bread.
The main indicator of the economy is profitability, which is a great result at low cost.
Our bodies love highly profitable activities. That's why people like to run downwind, go downhill, and go with the flow.
On this basis, it is possible to single out some of the sports areas as "skating".
We love cycling because we drive fast with minimal effort.
But it's even more enjoyable to ride a scooter, motorcycle, or car...- no effort at all.
So riding effortlessly comes first.:
1. Devices with a motor. (cars, motorcycles, electric scooters...) You need to buy them, store them somewhere, buy gasoline, charge the battery...
2. Skiing down the mountain. Then you have to climb the mountain, either on foot or on a ski lift.
3. Alloy. A lot of things are needed and you still have to get back.
4. SAILING. WIND, EQUIPMENT, PLAYGROUND. it's all.
YOU ALWAYS RETURN TO THE STARTING POINT. NO ADDITIONAL RESOURCES ARE NEEDED.
HIGHLY PROFITABLE ACTION.

It turns out that sailing is the best direction, and the question arises as to why it is not very popular and one might even say elitist. Two points - the equipment is expensive, and long, expensive training is required.
SCREENSAILING does not have these disadvantages - the sail is cheap, and the training takes literally minutes.

Plus, there are many positive properties of a round sail.:
1. Simplicity - it's probably impossible to come up with a simpler circle with a pen.
2.The round shape gives a maximum area with a minimum perimeter.
3. The collapsible sail is very quickly assembled and disassembled and carried in a small case.
4. A sail with a changing area - the frame consists of rods - by changing their number, we change the area of the sail.
This is very important because the sail must match the wind speed at the moment for comfortable riding.
In the rental version, this is not necessary, since you can simply take a sail of the required size, but for personal use
, yes, it is difficult to carry ten sails with you.
5. In order to move into the wind - the windward direction, the sail must be well stretched. A round frame for this
- ideal, as the arc holds the load well. Therefore, round arches and arches are used in architecture, and arc-
shaped structures are used in engineering. Drums are a good example. In the process of evolution, they were probably made in different shapes - square,
triangular, etc., but only round ones remained. Round embroidery hoop.
6. A push-type sail. The positive side of this can be explained as follows. If you surf in a wind of 5-8 m per second,
you will experience brisk movement downwind even without a sail. When moving in the windward direction on a windsurfer with a pulling sail
, the athlete's body is in the wind and therefore the acting, in this case, harmful force must be compensated.
With a pushing sail, there is no such force, since the athlete is hidden behind the sail, and there is no need to have a ballast additional part of the sail.
7. Cheapness - it will probably cost an order of magnitude cheaper than existing sails.
8.Low weight. With good performance, it will weigh an order of magnitude less than existing sails.
9. Extremely simple operation. it is carried out by moving the handle. No movement is required on the surf deck. Therefore, the training
lasts literally minutes and the widespread popularization of this simple reliable mechanism is possible soon.
10. Saping is gaining popularity now. By tying a mooring line to the boot, you can ride it with a round sail.
11.Versatility - suitable for use on any transport platforms: roller skates, skates, skate, ski, snowboard,
surf, sap, mountainboard, kart, buer ...
12. When moving, one hand is completely free, and the other slightly holds the sail resting on the shoulder. In windsurfing, for example, both hands are busy.
13.Can be used as a vehicle. For example, I surf fishing up the Volga.
Rowing against a fairly strong current would be tedious.
14. The resultant wind load is lower than that of a triangular sail - less tipping effect.

THE ROUND SAIL MAKES ELITE SMALL-SCALE SAILING DEMOCRATIC, ACCESSIBLE FROM CHILDREN TO PENSIONERS.
