🔍 Key Concepts

• 46 CFR Part 4 – Marine Casualties and Investigations • Definition of a marine casualty vs what makes it reportable • Special rules for groundings and collisions with aids to navigation

💭 Think About

• Ask yourself in which options the type of event itself (not just the cost of repairs or the severity of injury) automatically triggers Coast Guard interest. • Compare which events could affect safety of navigation for other vessels, even if there seems to be no damage to your own vessel. • Think about the difference between an injury needing only simple first aid and an injury that must be reported under Coast Guard rules.

✅ Before You Answer

• Verify in 46 CFR Part 4 which events count as a reportable marine casualty (e.g., groundings, collisions, injuries beyond first aid, significant property damage). • Check whether there are special reporting requirements when an incident involves an aid to navigation (like a buoy), regardless of apparent damage. • Confirm whether the dollar amount of equipment damage in one of the choices is above or below the threshold that would make it reportable.
