Is it false that radar reflectors are not necessary for all vessels?

Radar reflectors are devices designed to enhance the visibility of a vessel on radar by reflecting radar signals back to the source. While they significantly improve detection capabilities, particularly for smaller vessels, they are not mandatory for all types of vessels. This is because larger vessels, which are already equipped with more advanced radar systems, may be well-detected by other means or may not operate in areas where radar tracking is critical.

In certain situations, for instance during fishing activities in busy shipping lanes or while sailing in low-visibility conditions, using radar reflectors could be beneficial. However, there is no universal requirement making them necessary for every vessel type. Thus, claiming it is false that radar reflectors are not necessary for all vessels correctly captures the essence that while they can be important, they're not a regulatory requirement for every kind of vessel.
