About This Tool
This calculator estimates the static and dynamic thrust of a propeller based on engine power and propeller diameter. It provides a key metric for understanding a boat's potential for acceleration and load-carrying capacity.

Key Concepts:

Static Thrust: The thrust produced at zero speed.
Dynamic Thrust: The thrust produced while underway.
Disk Area: The area of the circle swept by the propeller.
Thrust-to-Weight: A primary indicator of acceleration performance.
