A Practical Guide

What To Check, And How Often

This checklist is a starting point for owners and captains. Intervals depend on the yacht, the engines, how she is used and the manufacturer’s instructions, so always follow the manuals for your own equipment. A planned maintenance system turns a list like this into dates and running hours that are tracked for you.

Daily Or Before Each Trip

Engine oil, coolant and gearbox oil levels.
Raw-water strainers, fuel filters and water separators, for debris and water.
Bilges, bilge pumps and bilge alarms.
Steering and engine controls, for free movement.
Navigation lights, VHF radio and safety equipment in place.
Fuel, fresh water and holding tank levels.
A look and a listen: leaks, drips, new noises and smells.

Weekly Or Monthly

Batteries: voltage, terminals and charger operation.
Belts, hoses and clamps on engines and generators.
Seacocks: operate them, so they stay free.
Anodes: note how quickly they are wasting.
Fire extinguishers and fire detection: gauges and test functions.
Lifejackets, flares and liferaft details.
Generator: run it under load, not just idling.

By Running Hours

Engine and generator oil and filter changes at the manufacturer’s interval.
Fuel filter replacement.
Raw-water impeller inspection or replacement.
Coolant and heat-exchanger checks.
Gearbox oil and shaft seals.
Valve clearances and other major services at the intervals in the manual.

Annually Or Seasonally

Haul-out inspection: hull, anodes, propellers, shafts, rudders and through-hull fittings.
Antifouling and underwater gear.
Safety equipment servicing and certificates: liferaft, extinguishers, EPIRB.
Electrical inspection, including shore-power connections and bonding.
Rigging, deck hardware and windlass.
Air-conditioning and watermaker servicing.
Spare parts, manuals and certificates reviewed and updated.

Records Worth Keeping

What was done, the date and the running hours.
Who did it and which parts were used.
Photos before and after.
Manuals, certificates and warranties in one place.

Watch For Repeat Faults

If the same fault returns, treat it as a signal rather than a routine job. Anodes that waste quickly, a pump that keeps losing its prime and an engine that fouls early all have causes worth tracing. See Yacht Fault Diagnosis.

This checklist is general guidance only. It is not a substitute for the manufacturer’s instructions or a survey of your own yacht.
