Whether your boat is coming ashore for winter or staying afloat, here is a useful checklist compiled by Yachting Monthly's experts to help you remember everything

Afloat on a mooring

  • Ensure your mooring line isn’t going to chafe. Preferably use chain and run it through hosepipe. Add a second, fall-back line.
  • Remove as many items as you can, including sails, cushions, curtains, clothes and bedding. Parking up at a nearby marina during this operation can save precarious dinghy trips.
  • Leave lockers, bin lids and sole panels open.
  • Remove any food, empty the fridge and leave the door wedged open.
  • Pump the toilet dry after flushing with fresh water. Deodorise and clean the holding tank if you have one, then leave it empty and dry.
  • Empty all water tanks (don’t forget the calorifier if you have hot water) and run the pipes and pumps empty.
  • Empty and sponge out the bilges.
  • Clear cockpit and deck drains.
  • Burn off any gas in the pipes and turn it off at the bottle.
  • If you need power on board – to run an automatic bilge pump, say – then fit a wind generator to keep the batteries topped up.
  • Disconnect, clean, grease and reconnect battery terminals. Disconnect any unnecessary cables to avoid any power drain.
  • Ventilation is essential in keeping the boat free from damp and mildew. Create or install a few weatherproof, secure vents. If you don’t have all-weather vents on hatches, fitting them will make all the difference.
  • Flush out headsail furler swivels with fresh water.
  • Take flares home to dry-store.
  • Disconnect the mast wiring. Clean it, coat it with silicone grease and reconnect it.
  • Remove all running rigging, wash in fresh water, dry and hang below or at home.
  • Remove all sails from spars and furlers.
  • Take off any external navigation instruments, such as chartplotters (if possible) and store inside the boat, or at home.
  • Change the engine oil and filter to prevent any acidic traces in the old, contaminated oil from damaging engine parts
  • Top off your fuel tanks to avoid condensation forming and thus help to prevent diesel bug contamination.
  • Check and clean navigation light terminals. Daub them with silicone grease to prevent poor connections.

Afloat in a marina
As above, but:

  • Keep your batteries charged by fitting a two-stage shore power battery charger with a maintenance level charge. Ensure any shore power lead has an integral protection breaker and preferably fit a galvanic isolator to protect your through-hull fittings from corrosion.
  • If your boat doesn’t need 12 Volts, disconnect and take your batteries home to clean, top up if necessary and keep on charge.
  • Place a small oil-filled heater on board with a thermostat and set to low.
  • A dehumidifier is useful if your boat is particularly damp, but otherwise a little heat and good ventilation will keep her sweet.

Ashore
As above plus:

  • Service and shut seacocks – or remove the hoses and leave them open for extra ventilation (warning: leave a note somewhere obvious to remind you to replace them before launching).
  • Take transducers out for added ventilation (see warning above).
  • Stuff a rag up all the skin fittings and the exhaust (see warning above).
  • Remove fenders to stop them scratching the topsides in the wind.
  • Grease all rigging screws and replace all split pins.
  • Unstep the mast at least once every three years and check it thoroughly.
  • Remove the anchor and chain from the anchor well or foredeck to prevent its weight distorting the hull. This is very important for wooden yachts.
