Several merchant ships are arriving at the scene of a distress incident. One of them must assume the duties of the Coordinator Surface Search (CSS). Which of the following statements is TRUE?

Correct Answer: Option B — The CSS must be established by mutual agreement between the ships concerned.

In multi-vessel search and rescue operations, the Coordinator Surface Search (CSS) is not automatically designated by arrival order. Instead, per IAMSAR and SOLAS guidelines, the role must be established and agreed upon mutually between the participating vessels to ensure optimal coordination.
