We use a specialized formula to estimate the thrust needed based on your boat’s dimensions and wind exposure. Here’s a simplified version of the formula:

Formula: Required Thrust = (Boat Length x Boat Height x 0.5 x 0.75 x Wind Pressure)

- Length: Measure from bow to stern above the waterline.

- Height: Include superstructures but exclude masts for sailboats.

- Wind Pressure: Based on average wind forces (Beaufort scale 5 or 6).

This formula helps gauge the power needed for safe maneuvering, especially in windy conditions.

Choosing the right bow thruster size depends on several key factors, including the length, height, and weight of your boat, as well as its wind exposure. A properly sized bow thruster provides reliable control during docking and tight maneuvers, making it essential for both small and large vessels.

Our Jet Thruster Calculator simplifies the process by using these measurements to determine the ideal thrust for boats from 25 to 60 feet in length. By entering basic details, you’ll get an accurate recommendation tailored to your boat’s specific needs.

For larger vessels or catamarans with increased wind resistance, our Dual/Combi Jet Thruster System offers enhanced control by combining the power of two pump units, giving you the confidence to handle challenging conditions with ease.

Jet thrusters are compact, efficient, and require no external tunnel installation, unlike traditional thrusters. This makes them easier to install in shallow-draft vessels and reduces drag on the boat. Jet thrusters also feature internal components that are better protected from external debris and damage.
