Specifications of your vessel (Thrust pressure calculation in Kgf)

Select vessel type

Motor yacht Sailing yacht

Hull type Fiber glass/wood/steel Aluminum

Vessel length: Sail boot

Height above the water line: Sail boot

length unit

height unit

Why?
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.

Wind capture:

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
