Which Jet Thruster?

Here you can select the required parts and calculate the price

You can use the module below to calculate the required thrust pressure in Kgf for your vessel under normal circumstances. In this calculation, the exerted wind pressure is the most important criterion. Each vessel is different: in the calculation we do not take into account the point of application with respect to the torsion moment of the vessel, nor the form of the underwater hull (long keel, deep keel) and the water current. This calculation is indicative. We recalculate and reassess each request ourselves.

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

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
