What is the primary concern when a vessel experiences cavitation?

Cavitation is a phenomenon that occurs when the pressure in a fluid falls below its vapor pressure, leading to the formation of vapor bubbles. When these bubbles collapse or implode, they can cause significant damage to surfaces such as propellers and other components of the propulsion system. The primary concern in the context of a vessel experiencing cavitation is indeed the loss of propulsion.

This is because cavitation can disrupt the flow of water around the propeller and lead to a significant reduction in its efficiency. As a result, the vessel may not be able to move effectively through the water, which can impair its ability to steer or maintain speed. In severe cases, cavitation can even lead to complete loss of power if the propulsion system fails.

While cavitation can also lead to increased wear and tear on the vessel's components, and potentially contribute to overheating issues indirectly, the most immediate and direct consequence that affects navigation and safety is the potential loss of propulsion. This makes it crucial for vessel operators to monitor and manage conditions that can lead to cavitation to ensure the safety and operational effectiveness of their vessels.
