For many boat owners, the end of the season arrives gradually.
The afternoons become shorter, the water gets cooler and the outings that seemed so easy in July begin to require a little more planning.
Eventually, there comes a weekend when the boat is cleaned, the equipment is put away and the RIB is prepared for a few months of rest.
Winter storage is an important part of ownership, particularly in regions where freezing temperatures or prolonged inactivity can affect mechanical and electrical systems.
A proper lay-up helps protect the boat and makes the return to the water easier when the season begins again.
Winterisation depends on where you live
There is no single winter-storage procedure suitable for every climate.
A RIB stored in a mild coastal region faces different conditions from one kept outdoors through freezing temperatures.
Humidity, salt exposure, sunlight, rainfall and storage duration all influence preparation.
The engine type, fuel system, batteries and installed equipment also matter.
Start with the manufacturer’s instructions and adapt the storage plan to the actual environment.
Clean the boat before storage
Cleaning removes salt, dirt and contamination that might otherwise remain on surfaces for months.
Rinse and clean the hull, tubes, deck and accessible fittings using suitable products.
Pay attention to areas where dirt and moisture collect.
Allow upholstery, lockers and equipment to dry appropriately before covering the boat.
Putting a wet boat into poorly ventilated storage can encourage mould and other moisture-related problems.
Inspect the tubes
Check tube fabric, seams, valves, rubbing strakes and attachment patches.
Look for damage that should be repaired before storage.
Follow the manufacturer’s recommendations for inflation pressure and long-term storage.
Temperature changes can affect pressure, so a setting appropriate for one environment may not be appropriate for another.
Avoid applying universal deflation or overinflation rules.

Prepare the engine correctly
Engine winterisation is one of the most important tasks.
Depending on the engine, it may involve servicing, flushing, fuel-system preparation, lubrication and other procedures.
Freezing conditions introduce particular concerns where water can remain in components.
However, modern outboards differ considerably in their design and storage requirements.
Follow the engine manufacturer’s current instructions for the exact model.
If you’re uncertain, professional servicing is preferable to improvising a procedure that may cause damage.
Fuel-system preparation
Fuel can deteriorate during extended storage, and the appropriate preparation depends on the fuel type, engine and tank arrangement.
Some manufacturers recommend particular stabilisation or storage procedures.
Others specify additional precautions for certain fuel systems.
Avoid assuming that every boat should be stored with the same fuel level or that a particular additive is suitable for every engine.
The correct approach is to follow the relevant manufacturer’s instructions and applicable fire-safety requirements.
Batteries and electrical systems
Batteries can lose charge during storage.
The appropriate care depends on battery chemistry, temperature and whether equipment must remain powered.
Some installations may use suitable maintenance charging, while others require different arrangements.
Lithium-based systems can have storage-temperature and charging restrictions that differ from lead-acid batteries.
Check the battery and boat manufacturers’ instructions.
Essential systems, including any bilge-pump arrangement intended to remain active, must be considered before disconnecting power.

Protect against trapped water
Water left in lockers, drains, hoses or other components can create problems during storage.
In freezing conditions, trapped water may cause damage as it expands.
Check the boat’s drainage arrangements and any installed freshwater systems.
Do not assume that every drain plug should be left open or closed; follow the boat’s storage instructions and consider the location and weather exposure.
A boat stored outdoors needs particular attention to rainwater accumulation.
Covers and ventilation
A suitable cover can protect the boat from weather and contamination.
However, it must be supported and secured properly.
Water pooling, repeated rubbing and inadequate ventilation can create new problems.
A cover should protect the boat without trapping persistent moisture.
Where possible, inspect the stored boat periodically, particularly after storms or heavy rain.
What about keeping the RIB afloat?
Some owners keep their boats in the water throughout winter.
This may be practical in suitable locations, but it requires attention to mooring arrangements, marine growth, batteries, drainage, weather and access for inspection.
The risks depend on local conditions.
A boat left afloat for several months should not simply be treated as if it were in dry storage.
A practical winter lay-up checklist
| Area | Main preparation |
|---|---|
| Hull and deck | Clean, inspect and dry |
| Tubes | Inspect, clean and manage pressure as instructed |
| Engine | Follow model-specific storage procedures |
| Fuel | Apply manufacturer-approved storage guidance |
| Batteries | Check condition and appropriate storage/charging method |
| Electrical systems | Inspect and manage essential circuits |
| Drainage | Prevent inappropriate water accumulation |
| Upholstery | Clean, dry and protect |
| Cover | Fit securely with suitable ventilation |
| Storage site | Check support, security and weather exposure |
A good winter lay-up makes spring easier
Winter preparation may not be the most exciting part of boating, but it is a worthwhile investment in the next season.
A clean, properly serviced and protected RIB is less likely to greet its owner with unpleasant surprises after several months of inactivity.
Follow the correct procedures, address existing problems and keep a record of the work completed.
Then put the boat away knowing that the next chapter is already a little easier.
