Which statement is true regarding a vessel navigating in a narrow channel?

The statement regarding a vessel navigating in a narrow channel that is true emphasizes that a vessel shall not impede the passage of any other vessel navigating within the channel or fairway. This principle is crucial for maintaining safety and facilitating the smooth flow of maritime traffic in confined waterways. Narrow channels often have limited space, making it essential for vessels to coordinate their movements to avoid collisions and ensure that all vessels can navigate safely.

When one vessel inadvertently impedes another's passage, it can lead to dangerous situations, potentially resulting in accidents. To uphold maritime safety, the rules clearly stipulate that vessels in a narrow channel must yield to those that are constrained by their draft or other limitations, ensuring that these vessels can proceed without obstruction. This helps to mitigate risks and maintain orderly conduct on the waterways.

The other options do not align with the established rules of the road. For instance, while there may be guidelines on signaling in certain situations, the requirement to sound a signal every hour does not relate specifically to the navigation rules for narrow channels. Similarly, the assertion that a vessel must always stay to the starboard side of the channel is not accurate, as channels may have different navigational requirements depending on local regulations and traffic conditions. Lastly, stating that a vessel is allowed to
