Fueling a sailing yacht with diesel

Fueling a sailing yacht with diesel is a straightforward but safety-critical task. Here’s a step-by-step guide to do it properly:

Before You Start

1. Prepare:

• Turn off all engines, generators, and open flames.
• Close hatches and ports near the fueling point to prevent fumes from entering the cabin.
• Have absorbent pads and a spill kit nearby.
• Make sure the correct fuel type (marine diesel) is being used.

2. Know Your Tank:

• Locate the diesel filler cap — not to be confused with water or waste caps.
• Know your tank capacity and current level to avoid overfilling.

Fueling Process

3. Secure the Yacht:

• Moor securely at the fuel dock.
• Set fenders properly to avoid movement during fueling.

4. Open the Filler Cap:

• Use a dedicated key if needed.
• Wipe the area clean to avoid contamination.

5. Insert Nozzle:

• Insert the nozzle firmly into the fuel inlet.
• Hold it steady to prevent splashing or sloshing.

6. Begin Fueling:

• Start slowly.
• Monitor the fuel gauge or listen to the sound of the tank filling.
• Keep a hand on the nozzle at all times—never leave it unattended.

7. Watch for Overflow:

• Stop when approaching full — most tanks gurgle or the pitch changes before overflowing.
• Some yachts have air vents — monitor for spillage there too.

After Fueling

8. Remove Nozzle Carefully:

• Let the remaining drops fall into the filler.
• Cap the tank tightly.

9. Clean Up:

• Wipe up any drips or spills immediately.
• Dispose of any used absorbent material safely.

10. Ventilate:

• Open hatches to air out fumes before starting the engine.

11. Start Engine and Check:

• Start the engine and check for proper operation.
• Check for any diesel smell or visible leaks in the engine bay.

⚠️ Tips & Warnings

• Never confuse fuel with water tanks.
• Avoid using jerry cans if you can — they increase spillage risk.
• If fueling from jerry cans, use a funnel with a filter or a fuel-safe transfer pump.
