Narrowboat Care Guide
Daily & Weekly Care
Owning a narrowboat means keeping on top of small tasks regularly to avoid bigger problems later.
Daily Checks (when cruising or living aboard)
    • Check engine oil level
    • Check coolant level
    • Look for leaks in the engine bay (oil, diesel, water)
    • Ensure bilge is dry or only has minimal water
    • Confirm batteries are charging properly
Weekly Tasks
    • Run the engine (if not cruising) to keep it healthy
    • Check fuel levels
    • Inspect ropes, fenders, and mooring pins
    • Clean windows and roof to prevent buildup
General Tips
    • Keep the interior ventilated to avoid condensation
    • Wipe down damp surfaces to prevent mould
    • Stay alert for unusual smells or sounds
Engine Maintenance
Your engine is the heart of your narrowboat, and regular maintenance is essential.
Routine Maintenance
    • Change engine oil every 200–250 hours or annually
    • Replace oil and fuel filters regularly
    • Check and top up coolant with antifreeze mix
    • Inspect belts for wear and tension
Cooling System
    • Ensure raw water intake (if fitted) is clear
    • Check skin tank system for leaks or overheating
Winter Care
    • Always use antifreeze
    • Run the engine periodically in winter
    • Drain water systems if leaving the boat unused
Hull & Exterior Care
Protecting the hull is crucial for long-term boat health.
Blacking
    • Reapply hull blacking every 2–3 years (bitumen)
    • Inspect for rust, pitting, or damage
Anodes
    • Check sacrificial anodes during blacking
    • Replace when significantly worn (usually every few years)
Exterior Maintenance
    • Wash and polish cabin sides to prevent fading
    • Touch up paint chips to stop rust forming
    • Keep drains and scuppers clear
Battery & Electrical Systems
A reliable electrical system is vital, especially if you live aboard.
Battery Care
    • Check electrolyte levels (for lead-acid batteries)
    • Keep terminals clean and corrosion-free
    • Avoid fully draining batteries
Charging
    • Engine alternator
    • Shore power
    • Solar panels (if installed)
Common Issues
    • Lights dimming = low battery
    • Appliances cutting out = voltage drop
    • Corrosion on terminals = poor connections
Water & Plumbing
Your onboard water system needs regular attention to stay safe and functional.
Fresh Water System
    • Refill water tank regularly
    • Use food-safe hoses
    • Clean tank occasionally to prevent contamination
Pipes & Pumps
    • Check for leaks or drops in pressure
    • Listen for pump running continuously (could indicate a leak)
Toilets
    • Maintain seals and valves
    • Empty cassette or pump-out tanks as needed
    • Use appropriate chemicals
Heating & Ventilation
Keeping your boat warm and dry is key to comfort and preventing damage.
Heating Systems
    • Solid fuel stoves
    • Diesel heaters
    • Gas heating systems
Maintenance
    • Clean flues and chimneys regularly
    • Service heaters annually
    • Store fuel safely
Ventilation
    • Never block vents (important for safety)
    • Open windows when cooking or showering
    • Use moisture traps if needed
Safety Essentials
Safety should always be a priority on a narrowboat.
Must-Have Equipment
    • Fire extinguishers
    • Fire blanket
    • Carbon monoxide alarm
    • Smoke alarm
    • Life rings or jackets
Regular Checks
    • Test alarms weekly
    • Check gas systems for leaks
    • Inspect fire extinguishers for pressure
Winterisation
Preparing your boat for winter prevents costly damage.
Key Steps
    • Drain water system or add antifreeze
    • Insulate exposed pipes
    • Keep batteries charged
    • Use a dehumidifier or moisture traps
If Leaving the Boat
    • Turn off gas supply
    • Disconnect unnecessary electrics
    • Secure all doors and windows
Long-Term Care & Inspections
A well-maintained boat lasts decades.
Annual Tasks
    • Full engine service
    • Inspect hull (in or out of water)
    • Check safety certificate requirements (UK: Boat Safety Scheme)
Every Few Years
    • Hull survey
    • Repainting cabin exterior
    • Replace worn components
Final Thoughts
Looking after a narrowboat isn’t difficult, but it does require consistency. Small, regular checks will save you money and prevent major repairs.
A well-cared-for narrowboat will:
    • Be safer
    • Hold its value
    • Be far more enjoyable to live on or cruise
