Question 3103 Deck General

The correct answer is C) an injury to a crewmember, passenger, or other person which requires professional medical treatment beyond first aid. A Serious Marine Incident (SMI) is defined in U.S. Coast Guard regulations as an injury to a crewmember, passenger, or other person that requires professional medical treatment beyond first aid. This is because an SMI can indicate a broader safety issue that needs to be investigated. The other answer choices, such as an allision or grounding without injuries, do not meet the regulatory definition of an SMI, which is focused on significant injuries requiring medical treatment.
