Preparing Your Boat for Winter Storage

Sponsored by:

Properly preparing your boat for winter storage is essential to protect your investment and ensure smooth sailing in the next season. Winterisation involves a series of maintenance steps, including engine care, hull protection, and mooring preparation. Skipping these tasks can lead to costly repairs, corrosion, and long-term damage.

Why Winter Boat Storage Matters

Leaving a boat exposed to cold temperatures, ice, and damp conditions can cause:

• Engine freezing and damage
• Hull deterioration or osmosis
• Mould and mildew growth inside the cabin
• Corrosion of metal fittings and electronics

Step 1: Engine Care

Winterising a boat engine is crucial. Follow these steps:

1. Flush the engine with fresh water to remove salt and debris.
2. Drain all water from the cooling system to prevent freezing.
3. Fill the engine with marine antifreeze designed for your engine type.
4. Change the oil and oil filter to prevent corrosion.
5. Check fuel lines, and add a stabiliser to avoid fuel degradation.

Step 2: Hull Protection

Protecting your boat’s hull over winter prevents cracking, blistering, and algae growth:

• Clean the hull thoroughly, removing barnacles and debris.
• Apply a winter-grade wax or protective coating.
• Inspect for cracks, blisters, or damaged gel coat and repair as needed.
• Consider using a shrink-wrap cover or marine-grade tarp.

Step 3: Interior and Electronics

Moisture and freezing temperatures can damage your boat’s interior and electronics:

• Remove cushions, fabrics, and electronics to store indoors.
• Use a dehumidifier or moisture absorbers inside the cabin.
• Disconnect batteries, clean terminals, and store in a warm, dry place.

Step 4: Mooring and External Preparation

If your boat remains on a mooring over winter, additional steps are required:

1. Check mooring lines for wear and replace if necessary.
2. Install fenders in areas prone to ice damage.
3. Ensure bilge pumps are functioning or remove them if appropriate.
4. Cover the boat with a winter-grade, breathable cover to prevent condensation.

Conclusion

Winterising your boat is a vital seasonal maintenance task that saves time, money, and stress in the long run. By following these steps for engine care, hull protection, interior maintenance, and mooring preparation, your boat will emerge from winter in optimal condition and ready for the new boating season.
