Which action is a proper step before refueling?

• A. Moor the boat securely to the dock
• B. Fill portable tanks on the boat
• C. Keep hatches open
• D. Smoke during fueling

Answer: (A)

Securing the boat to the dock before refueling keeps the vessel from moving during fuel transfer, which helps prevent spills, hose movement, and accidents. A stable, moored position provides a safe work area for handling the fueling equipment and reduces the risk of fuel coming into contact with ignition sources. The other options create direct hazards: filling portable tanks on the boat can cause spills and vapors aboard; keeping hatches open allows fumes to accumulate inside; smoking during fueling is a serious fire risk and is prohibited.
