When would it NOT be necessary to immediately notify the U.S. Coast Guard? (small passenger vessel regulations)

Correct Answer: Option D — Damage amounting to $2,000

46 CFR 4.05-1 defines reportable marine casualties. While loss of life, medical treatment beyond first aid, and major seaworthiness damage require immediate notification, a $2,000 damage threshold is not a standard trigger for immediate reporting under current small passenger vessel regulations, which focus on safety-critical incidents.
