Question 59 RVR05 - Master of LT 100 GRT

The Correct Answer is B **Why option B is correct:** Option B describes an incident that meets the standard definition of a Serious Marine Incident (SMI) regarding injury. A key criterion used by regulatory bodies (such as the U.S. Coast Guard, under 46 CFR 4.03-2) for defining an SMI is an injury to a crewmember, passenger, or other person that requires professional medical treatment (usually defined as treatment beyond first aid, such as suturing, X-rays, or admission to a hospital) or results in a loss of consciousness or loss of life. This level of injury triggers mandatory reporting and investigation protocols, classifying the event as "serious." **Why the other options are incorrect:** * **A) An allision that results in $500 damage to a boat dock:** This level of property damage is typically too low to qualify as a Serious Marine Incident solely based on cost. While the specific threshold varies by jurisdiction, SMIs generally involve damage that exceeds a significantly higher monetary limit (often $25,000, $50,000, or more, depending on the specific regulation) or involves "significant harm" to property. A minor incident causing $500 in damage would usually be a reportable marine casualty, but not a "Serious Marine Incident." * **C) A vessel experiencing bottom suction over a sandbar that does not result in injuries and/or any damage to the vessel:** This event, where the vessel touches bottom without resulting damage or injury, is an operational deviation or a "grounding" but is not considered "serious." An SMI requires a consequence such as major damage, loss of life, serious injury, or complete loss of the vessel. Since there was no injury or damage, it does not meet the criteria for an SMI. * **D) None of the above:** Since option B is a definition of a Serious Marine Incident, this option is incorrect.
