Owning a boat isn’t just about setting sail on sunny days, it’s also about the behind-the-scenes upkeep that keeps your vessel safe, comfortable, and ready to go when the tide is right. Regular maintenance doesn’t have to be time-consuming or complicated. Setting aside just a little time each month for some key checks can help you spot problems early, avoid costly repairs, and enjoy peace of mind.
Here’s a simple monthly maintenance checklist that works for both sailboats and motorboats. Pin it in your cabin—or set a reminder in your calendar and keep your boat shipshape all year round.
🔍 1. Check the Bilge
Your bilge is often the first place where signs of trouble appear. A quick monthly inspection can help detect leaks, fuel spills, or other issues before they escalate.
-
Look for excess water—your bilge pump should never be running constantly.
-
Check for unusual odours (such as diesel, oil, or gas).
-
Ensure the pump and float switch are functioning properly.
-
Clean out any debris that could clog the pump or filters.
Tip: Keep a torch handy to inspect hard-to-see areas.
2. Inspect Seacocks and Through-Hulls
Seacocks control the water flow in and out of your boat—through-hull fittings that, if faulty, could lead to severe flooding.
-
Exercise each seacock (open and close it) to prevent seizing.
-
Check for signs of corrosion, especially on bronze fittings.
-
Ensure hose connections are tight and the clamps are free from rust.
-
Confirm that each seacock is accessible and clearly labelled for emergency use.
This is especially important for boats that stay in the water year-round, such as those berthed in Sutton Harbour.
3. Tighten Hose Clamps
Hose clamps are small but critical components that secure water, fuel, and waste hoses.
-
Give each clamp a gentle twist with a screwdriver to ensure it’s snug.
-
Look for any signs of rust, fatigue, or perishing on hoses.
-
Double-clamp below the waterline and ensure there’s no movement at the fittings.
Pay special attention to engine cooling and bilge discharge hoses—they’re the most common sources of leaks.
4. Galley Gas Safety
Your onboard gas system deserves regular checks, especially if you cook often.
-
Smell for gas leaks—LPG is heavier than air and will sink into the bilge.
-
Verify that the gas locker is appropriately sealed and ventilated.
-
Inspect hoses and regulators for cracking or wear.
-
Ensure the shut-off valve is easily accessible and functioning properly.
-
Test your gas alarm monthly if fitted.
If in doubt, have your system checked by a certified marine gas engineer.
Other Quick Tasks Worth Including
