CLAIMS

1. Arrangement for displaying airflow conditions around the sails, including a wind sensing device (200a, 200b, 200c, 450), a central device (600) and a signal transmission device (300a, 300b), and at least one of the wind sensing devices (200a, 200b, 450) being a built-in wind sensor device fixed on the sail (200a, 200b, 200c),

characterized in that

the built-in wind sensor device (200a, 200b, 200c) is connected to the central device (600) and contains electronic units.

2. The arrangement according to claim 1, characterized in that

a controller device (400a, 400b) is located between the built-in wind sensor device (200a, 200b, 200c) and the central device (600), where the devices are connected by the signal transmitter device (300a, 300b).

3. The arrangement according to claim 1 or 2, characterized in that

the built-in wind sensor device (200a, 200b, 200c) contains moving unit (201), accelerometer unit (202a, 202b), signal transmitter unit (203), controller unit (204) and signal converter unit (205), and at least one of the accelerometer units (202a, 202b) is located in the moving unit (201).

4. The arrangement according to any of claims 1 to 3, characterized in that

it contains an external wind sensor device (450), a rudder sensor device (460) and a graphic user interface, all connected to the central device (600).

5. The arrangement according to any of claims 1 to 4, characterized in that

the built-in wind sensor device (200a, 200b, 200c) contains magnetic sensor unit (210a, 210b) and/or magnet (230), and at least one of the magnetic sensor units (210a, 210b) is located on the moving unit (201).

6. Procedure for applying the arrangement according to claim 1 , where the flow around the sail is observed with the built-in wind sensor device mounted on the sail (200a, 200b, 200c), the flow is described by the measured data and based on the measurement data the crew is supported in navigating the boat, characterized in that

the built-in wind sensor device (200a, 200b, 200c) is connected to the central device (600) and electronic units are used in the built-in wind sensor device (200a, 200b, 200c).

7. The procedure according to claim 6, characterized in that

electronic signals of the built-in wind sensor device (200a, 200b, 200c) are processed and evaluated before the central device (600) and then forwarded to the central device (600).

8. The procedure according to claim 6 or 7, characterized in that

acceleration values are measured at the moving point and the stationary point of the built-in wind sensor unit (200a, 200b and 200c) compared to the sail, and the calculated acceleration difference describes the flow around the sail.

9. The procedure according to any of claims 6 to 8, characterized in that

characteristics of the air flow far from the sail and unforced, and also the angle of the rudder are measured.

10. The procedure according to any of claims 6 to 9, characterized in that

deviation from the geomagnetic direction (220) is measured at the point of the built-in wind sensor device (200a, 200b, 200c) moving and at the point stationary compared to the sail.
