Tips for winter

Well prepared for winter time

Is your boat prepared for winter? Is she ashore or in the water?

The days are getting shorter and it is getting colder, but we really have a good season behind us. To be able to enjoy you boat next year as well, we have a few tips to prepare it for winter.

Maintenance tanks

  • Make sure that the water tanks are empty
  • Make sure that no water can stay in the loops of the pipes
  • Make sure that the waste tank is empty
  • Fill the fueltank to avoid condensation or empty it totally
  • Add an additive when you use biodiesel to avoid the growth of bacteria
  • Make sure that there is no fuel left in the exhausting pipes


  • Take the electronics, that can be removed, with you and store it dry
  • Protect open electrical connections with contact spray to prevent corrosion
  • Make sure the spaces are well ventilated to avoid condensation
  • Check all electrical connections that can handle high voltage. Examples are start engine and bow- and stern thruster. Bolts and nuts can get loose due to big fluctuations in temperature


  • If you don’t have maintenance free batteries: check the level of fluid in the batteries
  • Fill the battery when needed with distilled water
  • Disconnect the poles
  • Charge and test the batteries twice during the winter period or keep the batteries going using a charger

Maintenance of your engine

  • Preparing for winter is the ideal time to change the oil and fuel filters
  • Download the parts guide to see in one glance what parts you need. You can order the service kit you need as well to change filters and other motor parts ed.
  • Replace the motor oil on a yearly
  • Replace the oil of the gearbox
  • Shut down the electrical supplies to your engine
  • Check the level of coolant in your engine and replace it
  • Check the intercooling for anti-freeze and enough protection
  • Make sure that the outside water system is empty and has anti-freeze

Maintenance of the cabin

  • Remove all books and charts from your boat
  • Put the matrasses upright so they can air
  • Put a dehumidifier in every room (for example a dry-bag = reusable)
  • When using a winter tent please make sure there is good ventilation from the deck to the cabin.

When staying in the water

  • Make sure that your ship is properly moored with two extra lines on the back of the boat
  • Moor with lines with some extra length: the difference in water height can be up to 65 cm during storm. The harbour master can then easily moor your boat again in its berth.

Prevent damage of the hull 

When you leave the boat in the water this winter, never step on it when there is ice!
Especially during the thaw period the ice around the boat moves. This ice works like a razor on the hull and causes deep cuts.

We advise you to check the area around the waterline for any damages of gelcoat of the osmose protection layer. Not repairing the cuts on your hull can lead to increased moist in the polyester and even osmose.

If you are planning for a short lift-out ashore for the summer season: we are ready for you after April 10 (if weather conditions are good by then).
