In which casualty case is it UNNECESSARY to notify the local Coast Guard Marine Safety Office?

Correct Answer: Option B — Your vessel strikes and sinks an anchored sailboat costing a total of $20,000 for salvage and repair.

Under 46 CFR, property damage under statutory limits or minor groundings quickly cleared without structural impairment generally do not meet the mandatory criteria requiring immediate Coast Guard marine casualty notification, unlike fatal accidents or major structural failures.
