Jet Thruster Calculator
Jet Thruster Calculator
How does the calculator work?
Displacement and current affect thrust control, but wind capture is the primary counterforce to thrust.
Enter parameters below to estimate thrust required for the given conditions.
Vessel Length (in ft.)
Length over all, including extensions
Height Above Water Line (in ft.)
Average the cross-section of rigging and superstructure
Wind Capture
Anticipated conditions in knots/Beaufort scale
Note: Small consistent forces move large vessels, but strong cross-currents may require greater thrust for any vessel.
