The distance your vessel moves forward with each revolution of the propeller is called what?

The distance your vessel moves forward with each revolution of the propeller is known as pitch. Pitch refers to the theoretical distance that the vessel would travel in one complete revolution of the propeller, assuming there is no slip occurring. It is a crucial concept in understanding how a propulsion system works, as it gives insight into the vessel's efficiency and how effectively it converts engine power into forward motion.

In practical terms, if the pitch is defined at a certain measurement (e.g., in inches), it indicates how far the vessel would travel if the propeller were to bite into the water and propel the boat forward without any loss of movement. The concept of pitch is fundamental for mariners when considering the design and selection of propellers to ensure optimal performance based on the vessel's intended use and operating conditions.
