What is the format used for querying a boat file?

The correct response is based on the requirement for specific identifiers when querying a boat file. The use of the Registration Number and Coast Guard Document Number is essential because these unique identifiers allow operators to accurately access and retrieve information about a particular boat.

The Registration Number is typically issued by the state where the boat is registered and is crucial for tracking ownership and legal status. The Coast Guard Document Number serves a similar purpose for vessels that are federally documented, providing a standardized reference that is recognized across jurisdictions. Together, these identifiers ensure that the query is precise and minimizes the risk of retrieving incorrect or unrelated data.

Other choices do not involve the specific identifiers needed for boat files. For example, combining OAN and VIN is more relevant to motor vehicles, while querying by VIN or License Plate Number pertains specifically to automobiles rather than boats. Similarly, model numbers and registration dates are not unique identifiers recognized in the context of boat file queries, making them insufficient for accurate querying.
