VetusOnline Electric Propulsion Motor Sizing Calculator
This calculator is intended for displacement boats only. It estimates the required propulsion power based on waterline length, displacement and desired speed, then matches the result to the nearest suitable Vetus electric propulsion motor. Desired speed is checked against hull speed to prevent unrealistic input values.
This calculator is intended for displacement boats only.
Use LWL where possible. If unknown, overall boat length may be used as a guide.
Enter the actual operating displacement.
For displacement boats, desired speed is checked against hull speed.
Dynamic mode adds a small practical safety margin when matching the motor.
