What does "In-Sight" signify when referring to vessel navigation?

The term "In-Sight" in vessel navigation indicates that a vessel or object can be seen with the naked eye. This concept is important for navigating and ensuring safety on the water, as visual identification of other vessels is a key aspect of collision avoidance and navigation. Being "in sight" implies that the navigation officer can visually confirm the presence of other ships, landmarks, or navigational aids, allowing for better decision-making and situational awareness while underway.

While other options may relate to vessel navigation in different contexts, they do not accurately capture the specific meaning of "In-Sight." For instance, the visibility to radar equipment or dimensions of proximity to other vessels pertains to different navigational considerations. In contrast, "In-Sight" strictly refers to visual confirmation, making the understanding relevant for navigational safety and operations.
