What best describes "in-sight" in relation to navigation?

The term "in-sight" in navigation specifically refers to the capability of seeing other vessels from your position on the bridge. This understanding is crucial for safe navigation at sea, as it allows for the ability to assess traffic density, determine interaction with other vessels, and make informed decisions to avoid collisions.

When vessels are "in-sight" of each other, it enhances situational awareness, allowing for better communication and navigation strategies. Observing other vessels aids in abiding by the "Rules of the Road" and ensures that a mariner can respond promptly to any navigational hazards or changes in conditions.

The other aspects, such as the ability to see the shoreline, read navigation charts, or communicate with nearby vessels, do not capture the precise meaning of "in-sight" within the context of navigation. While these skills are important in their own right, they do not directly relate to the visual confirmation of other vessels present in the navigation area.
