Tips for Preparing Your Narrowboat for Winter

As winter approaches, preparing your narrowboat to withstand the colder months is crucial.  It’s important to protect it from potential weather-related damage and ensure it’s ready to go when the boating season returns. Winterising your narrowboat may seem like a big task, but taking preventive steps can save you a lot of time, effort, and money in the long run. Here are some essential tips to help you prepare your narrowboat for the winter. 

  1. Drain and Protect the Water Systems

One of the biggest concerns for narrowboat owners in winter is frozen pipes. When temperatures drop, any water left in your boat’s plumbing can freeze, expand, and potentially burst pipes and cause leaks. Start by draining your water tanks completely, including any holding tanks for drinking water and waste. Don’t forget to open all taps and showerheads to release any remaining water in the system.

For extra protection, consider using antifreeze designed specifically for marine systems. Run the antifreeze through the pipes to prevent any remaining water from freezing. Just be sure to follow the instructions carefully and avoid using automotive antifreeze, as it can be harmful in a marine environment. Keeping your water systems empty and protected during the winter will help you avoid costly repairs and plumbing issues when you’re ready to get back on the water. 

  1. Take Care of Your Engine and Fuel

Your narrowboat’s engine is another area that requires special attention before winter sets in. First, check the engine’s antifreeze levels to ensure they’re sufficient for the colder months. You may need to top it up or replace it to maintain proper levels.

Next, consider changing your engine oil, as old or dirty oil can cause problems when left sitting over winter. After changing the oil, run the engine briefly to distribute the fresh oil throughout the system. This simple step helps prevent corrosion and keeps the engine in good shape.

When it comes to fuel, topping up your tank can be a wise move. A full tank of fuel reduces the chance of condensation forming inside the tank, which can lead to water contamination and engine problems. Additionally, consider adding a fuel stabiliser to prevent the diesel from degrading over the winter. Diesel fuel can grow bacteria and form sludge if left untreated, so a fuel stabiliser is a worthwhile precaution. 

  1. Disconnect and Charge the Batteries

Batteries can lose charge in cold weather, especially if they’re not used regularly. To prevent battery damage, disconnect your narrowboat’s batteries and store them in a dry, secure place away from freezing temperatures. If possible, keep the batteries fully charged throughout the winter, as this helps prolong their life. You may want to use a trickle charger or a battery maintainer to keep them topped up.

If you can’t store your batteries off the boat, make sure they’re well insulated and check their charge periodically. A battery that goes flat can freeze and become unusable, leaving you with the additional expense of replacement when spring arrives.

  1. Prevent Damp and Ventilate Your Narrowboat Properly

Condensation and dampness can be a major issue for narrowboats over the winter. Without proper ventilation, your boat may develop mould, mildew, and an unpleasant smell by spring. To keep moisture at bay, ensure your narrowboat is properly ventilated throughout the winter months.

One effective way to reduce condensation is by placing moisture-absorbing crystals or dehumidifiers in your boat. These products help pull excess moisture from the air, reducing the risk of damp buildup. You can place them near windows, under beds, and in any other areas prone to condensation.

If your boat will be locked up for the winter, try to leave vents open or slightly cracked to allow air to circulate. Alternatively, if your boat has a heating system, consider setting it to a low temperature to prevent excessive cold and damp from settling in. 

  1. Secure and Clean the Exterior of Your Narrowboat

Winter can be harsh on a boat’s exterior, with strong winds, rain, ice, and snow all taking their toll. Start by giving your boat a thorough clean, as grime, algae, or salt left on the surface can damage your boat’s finish over time. A clean boat also makes it easier to spot any potential maintenance issues.

Once clean, secure anything that could be damaged or blown away by winter weather, such as fenders, ropes, and loose items on the deck. Make sure the boat’s canopy, if it has one, is in good shape and properly fastened. A damaged or improperly fitted canopy can allow water to leak inside the boat, causing additional dampness issues.

If possible, apply a coat of protective wax to your boat’s exterior to help shield it from winter weather. Waxing adds a protective layer to the paint and helps water roll off more easily, reducing the risk of rust and corrosion. You should also check any sealants around windows and doors for cracks or signs of wear, as these can allow water to seep into your boat during heavy rainfall. 

  1. Empty and Protect Your Gas Systems

If your narrowboat is equipped with a gas system for heating or cooking, it’s essential to winterise it as well. Start by turning off the gas supply at the source, and if possible, disconnect and store gas cylinders in a cool, dry location away from your boat. This minimises the risk of leaks and makes sure your boat is safe while it’s in winter storage.

Check your gas hoses and connections for any signs of wear or damage and replace them if necessary. Even if you don’t store your gas cylinders off the boat, it’s always a good idea to have the system thoroughly inspected before the next boating season to ensure safety. 

  1. Inspect the Mooring Lines and Check Security

If you’re planning to leave your boat moored for the winter, take the time to inspect the mooring lines and ensure they’re secure. Winter weather can increase the strain on mooring lines, so double-check that they’re in good condition and won’t fray or break. You might even consider using additional lines as a precaution.

Additionally, make sure any locks and security devices on your boat are in working order. Winter is a time when fewer people are around waterways, which can make boats more vulnerable to break-ins or vandalism. A good security check helps protect your boat from both the elements and unwanted attention.
