What does a Flag Hoist system consist of?

The correct answer is that a Flag Hoist system consists of lines suspended from the yardarms. This is because a Flag Hoist is a traditional maritime method used to communicate messages visually at sea, primarily between ships or from a ship to shore. The lines allow various flags to be raised and lowered to convey specific information or signals, based on a standardized flag communication system.

The use of lines suspended from yardarms enables the flags to be displayed prominently so that they can be easily seen over distances. This visual signaling is essential in nautical operations, as it provides a clear and immediate way to communicate important messages without relying on electronic means, which may be compromised or unavailable.

Other options such as lights or radio signals represent different methods of communication but do not pertain to the flag hoisting method itself. Emergency flotation devices also serve a different purpose entirely, unrelated to signaling and communication. These distinctions clarify why the line setup on yardarms is fundamental to understanding how the Flag Hoist system functions.
