Why might a vessel opt not to display lights while towing a distressed vessel?

The choice indicating that it is necessary for the safety of navigation highlights an important consideration in maritime operations. In certain situations, especially when towing a distressed vessel, the towing vessel may determine that not displaying standard navigation lights could enhance safety on the water. This decision may be based on several factors, such as the visibility of the distressed vessel or the tactical maneuvers needed to safely navigate the area.

When a vessel is towing, it may be important to signal its intention clearly to prevent confusion with other vessels. Displaying lights that do not communicate the towing situation effectively could lead to misunderstandings, potentially resulting in collisions or other navigational hazards.

In contrast, while the other options might seem plausible, they do not accurately address the complexities of navigation and vessel operations in these specific scenarios. A malfunctioning lighting system or not being required to display lights does not inherently connect to the rationale for prioritizing safety. Thus, the emphasis on navigation safety presents a more compelling reason for the choice not to display lights in certain towing situations.
