Yacht Maintenance Checklist

-
1. Engine and fuel system
-
After heavy usage (such as a single, long trip)
-
Check coolant and oil levels, and top up if necessary
-
Check for, follow up and address any fluid leaks
-
Check oil pads and replace as necessary
-
If you have reached 100 hours of usage (or as per manufacturer’s instructions), replace the oil and filter
-
Monthly routine
-
As per manufacturer’s guidance, apply WD40 to engine, components and control panel to prevent corrosion
-
If the boat has not been used that month, start the engine and allow it to reach operating temperature
-
Clean the water strainer
-
Annual checks
-
Check engine belts for wear and tension. Replace as necessary.
-
Check the fuel tank for rust and/or contamination
-
Ensure the hoses are not cracked and provide enough slack to account for vibration
-
Thoroughly inspect the tank, hose and fittings for evidence of leaks
-
Prior to winter storage, check antifreeze level and replace as necessary. Fill the tank prior to storage as per manufacturer’s instruction
-
2. Electrics
-
After heavy usage
-
Test all batteries for capacity level. Replace if necessary
-
Check that all wiring remains neatly bundled and secured and is well-clear of the exhaust system and bilge
-
Monthly routine
-
Check all running and interior lights and replace bulbs where required
-
Inspect bulkhead and engine connections to ensure there is adequate flex with no fraying
-
Check that wire connections and terminals remained sealed, with no evidence of corrosion
-
Annual checks
-
Check water level of battery
-
Clean exterior bulb contact points and apply anti-corrosion spray
-
3. Preventing corrosion
-
Monthly routine
-
Inspect the hull for evidence of corrosion such as leaks, blistered or peeling paintwork, deposits around stainless steel fixtures or whitish powder on an aluminium hull
-
Inspect the hull for evidence of corrosion such as leaks, blistered or peeling paintwork, deposits around stainless steel fixtures or whitish powder on an aluminium hull
-
Check steering cables, engine cables and connections and gear casings for corrosion
-
Annual checks
-
Replace zincs (either annually or every six months as per manufacturer’s instructions)
-
4. Hull maintenance
-
Monthly routine
-
Inspect for hull, keel and rudder damage and arrange for any necessary repairs immediately. Treat any scratches or gelcoat damage as per manufacturer’s instructions
-
Check the condition of the teak and renew as necessary
-
Annual checks
-
All yachts require an annual haul-out for anti-fouling, zinc replacement (and repainting, where necessary). Contact your maintenance engineer well in advance of your preferred haul-out time (usually winter) in order to arrange this
-
5. Bilge pumps and through-hulls
-
Monthly routine
-
Even where using automatic pumps, inspect blges frequently to ensure they are clean and free to circulate
-
Check through-hull strainers, intake and discharge components to ensure they are not blocked by debris or marine growth
-
Ensure valve handles are securely attached to enable quick and smooth closure in an emergency
-
Inspect plugs and hoses for cracking
-
6. Ensuring crew safety
-
Pre-departure checks should include checking the presence and placement of all personal flotation devices, first aid kit and flares. These further checks should also be carried out on a monthly basis:
-
Thoroughly inspect flotation devices for wear or abrasion. If inflation devices are incorporated into a PFD, ensure the cartridges are secure and charged.
-
Check the use-by date on flares
-
Ensure fire extinguishers are in their designated accessible positions, and that they have been professionally inspected and appropriately tagged as up to date
-
Ensure lifelines or rails are in good condition
-
Test to ensure CO and fire alarms are working
-
Ensure you are up to date with galley stove inspection and servicing
