As the evenings draw in and temperatures start to drop, it’s the perfect moment for boat owners to start thinking about winter boat storage. A little preparation now can save a lot of hassle come spring — and help keep your pride and joy in top condition.
To make things easier, we’ve pulled together a handy checklist of winter storage tips, to help you get ahead of the chill.
Where to Store Your Boat
The first decision? Location. Will your boat be staying afloat on a berth or coming ashore?
- On a berth: Fit strong fenders and mooring lines, and consider rubber snubbers to soften the blow of winter storms.
- Ashore: Make sure your boat is securely set on chocks or a trailer, and double-check the condition of the cradle or legs. Neatly stow covers, halyards, and lines to avoid tangles and wear.
Don’t leave it too late — marina spaces fill up fast once the cold sets in!


Keep Your Boat Clean and Dry
A clean boat is a happy boat — and one that’s far less likely to greet you with mould and mildew in spring.
- Empty and deep-clean fridges, leaving doors ajar to prevent mildew.
- Open cupboards and drawers to reduce condensation.
- Use a dehumidifier or heater to keep the cabin dry.
- Cover open boats that don’t drain well to protect them from rain and snow.
Freshwater systems should be drained and cleaned, with taps left open to avoid freezing damage. Scrub seacocks with fresh water and keep them closed if your boat stays afloat.
Hull and Gear Maintenance
If you’re lifting your boat out of the water:
- Scrape off any dirt, weed, or barnacles from the hull.
- Book a lift-and-hold with your marina for a thorough wash and inspection.
- Store sails, spray hoods, windscreens, rigging, and soft furnishings indoors.
This is also a great time to spot any wear and tear — and get ahead of repairs before the new season begins.


Protect Your Tech and Engine
Electronics and mechanical systems need love too:
- Safely stow navigational gear and radios.
- Test electrical systems and remove batteries (a quick spray of WD40 can help prevent corrosion).
- Fully winterise your engine, gearbox, and stern gear — including replacing the impeller.
- Inspect steering and trim gear for any early signs of trouble.
Don’t forget: Remove any gas bottles stored onboard.
Winter Check-Ins
Even after your boat is packed away, it’s worth checking in regularly:
- Empty dehumidifiers and test heaters.
- Look out for water ingress, especially if your boat isn’t covered.
A quick visit every few weeks can make all the difference.

Don't skip the Insurance
Even if your boat is out of action, insurance is still essential. Winter weather, theft, and accidental damage can strike when you least expect it.
