The forward movement of a vessel in one revolution of its propeller is measured by __________.

• A. advance
• B. head reach
• C. the pitch
• D. transfer

Answer: (C)

The forward movement of a vessel in one revolution of its propeller is measured by the pitch. The pitch refers to the theoretical distance a propeller would move through the water in one complete rotation, assuming there is no slip. Understanding pitch is crucial for assessing the effectiveness of a propeller in generating thrust and how it impacts the vessel's speed and performance. Factors such as the design of the propeller, the angle of its blades, and the vessel's operational conditions can influence the actual distance traveled versus the pitch measurement, but pitch is a fundamental concept in naval engineering and marine operations. This helps operators in selecting the appropriate propeller for their vessel's intended speed and operational efficiency.
