The total wind capture surface area of the vessel is calculated based on the length and height of the vessel above the water line (including superstructure/rigging) you have entered. This total surface area is used to select the Jet Thruster best suited for your vessel.

Click this link to see an example of how the calculation is used.

5 Bft (Wind-force in Beaufort)
6 Bft (Wind-force in Beaufort)
7 Bft (Wind-force in Beaufort)
Wind capture:
The total lateral surface area of the vessel above the water line in m² x 0.5 (half the boat length) x 0.75 (correction factor) = Lateral wind capture surface area in m².

On the Beaufort scale, the following wind pressure is displayed in Kg per m².
Bf 4 ->   2.2 Kg p/m²
Bf 5 ->   4.4 Kg p/m²

Bf 6 ->   7.5 Kg p/m²

Bf 7 -> 12.0 Kg p/m²

12/24V Jet Thruster system
