Which of the following is a reportable Marine Casualty?

• A. Unintended grounding or allision with a bridge
• B. Loss of life
• C. Minor propeller damage
• D. Weather advisory

Answer: (B)

Understanding what counts as a reportable marine casualty centers on events that involve harm to people or significant damage that must be communicated to authorities. Loss of life is inherently a reportable marine casualty because it represents the most severe outcome and requires immediate notification and investigation by the appropriate regulator. The other scenarios don’t automatically meet the threshold from the description alone: an unintended grounding or allision with a bridge could be reportable if it caused damage or injuries, but the statement doesn’t confirm that; minor propeller damage by itself usually doesn’t rise to a reportable casualty; and a weather advisory is not a casualty at all.
