According to navigation rules, which vessel has the obligation to keep clear in a narrow channel?

In navigation rules, particularly regarding narrow channels, the general principle is that certain types of vessels have the obligation to keep clear of others to ensure safe navigation. The requirement for vessels less than 20 meters, sailing vessels, and vessels engaged in fishing to keep clear recognizes the need for larger vessels, which may have limited maneuverability, to navigate safely in these confined areas.

A vessel less than 20 meters is often considered more maneuverable compared to larger vessels and is therefore expected to keep a safe distance. Similarly, sailing vessels may have limited ability to maneuver, especially under certain conditions, hence the expectation for them to give way. Vessels engaged in fishing, especially if they are using gear that restricts their ability to maneuver, must also keep clear of larger vessels navigating the channel.

By stating that all these vessel types have the obligation to keep clear, the response accurately reflects the navigation rules aimed at maintaining safety in narrow channels, where the maneuvering capability of larger vessels is critical. This rule helps avoid collisions and ensures that all vessels can navigate safely and effectively.
