What must be on board and available for inspection by a law enforcement officer whenever a vessel is being operated?

The correct answer to this question emphasizes the importance of having personal flotation devices (PFDs) readily available on board for each person on the vessel. Under Florida boating law, it is required that all vessels carry sufficient approved PFDs for every individual on board, and these must be accessible at all times. This requirement is in place to ensure the safety of everyone on the vessel in case of emergencies such as capsizing or man overboard situations.

While the other options may be relevant in certain contexts—like having emergency contact information or navigating with marine insurance—the law specifically mandates the availability of PFDs for every person on board as a critical safety measure. Ensuring that officers can inspect these devices upholds regulation compliance and promotes overall boating safety.
