How to prepare your yacht for winter storage at Chichester Marina

As the sailing season comes to an end, it’s time to think about winter storage for your yacht. Properly preparing your boat for the colder months can prevent damage, extend its lifespan, and ensure a hassle-free relaunch in the spring.

At Peerless Marine, we help Chichester-based sailors with rigging inspections, winter lay-up maintenance, and pre-season checks to ensure their yachts are well cared for during the off-season.

Here’s a step-by-step guide to winterising your yacht at Chichester Marina.

1. Choosing between dry storage & in-water berthing

The first step is deciding where to store your yacht over winter. Both options have benefits:

Dry Storage (Lift-Out & Hard Standing at Chichester Marina)

Best for: Long-term protection, hull maintenance, and full winterization. 

Pros: 

✔ Prevents hull fouling and osmosis. 

✔ Easier access for antifouling, repairs, and rigging checks. 

✔ Less exposure to winter storms and potential marina damage. 

❌ Cons: Requires proper support (cradle/props), and spaces can fill up quickly.

In-Water Berthing

Best for: Short lay-ups or if you plan to sail occasionally during winter. 

Pros: 

✔ Less hassle—no need to relaunch in spring. 

✔ Some protection from frost due to water temperature stability. 

❌ Cons: 

- Higher risk of storm damage and chafing on mooring lines. 

- More risk of hull fouling and submerged growth.

Local tip: Chichester Marina offers lift-out services—book early as demand is high in autumn!

2. Hull & deck preparation

Hull Cleaning & Antifouling

🛠 If storing ashore, pressure wash the hull immediately after lift-out to remove barnacles and algae. 

🛠 Check for osmosis blisters or gelcoat damage and address any repairs. 

🛠 If needed, apply a fresh coat of antifouling paint before relaunching in spring.

Chichester Marina Services: Professional hull cleaning and antifouling services are available onsite.

Deck & Rigging Care

✔ Wash down all deck fittings, winches, and hardware with fresh water to remove salt. 

✔ Remove sails, dodgers, and sprayhoods for cleaning and storage. 

✔ Inspect running and standing rigging for signs of wear or corrosion - this is a great time to book a rigging inspection with Peerless Marine!

3. Engine & fuel system

Proper engine care is essential for avoiding damage from cold temperatures and fuel degradation.

✔ Flush the cooling system with fresh water and add antifreeze (for raw-water-cooled engines). 

✔ Top up fuel tanks and add a fuel stabilizer to prevent diesel bug growth. 

✔ Change the engine oil and filters to prevent sludge buildup over winter.

 ✔ Check and charge batteries—either remove them for storage or keep them on a trickle charge.

Pro Tip: Start the engine every few weeks (if stored in-water) to prevent seizing.

4. Protecting your rigging & sails

Winter storms, moisture, and UV exposure can weaken your rigging and sails.

✔ Remove sails, clean, and store them dry—avoid mildew buildup. 

✔ Check halyards for chafing and consider replacing worn-out lines. 

✔ Loosen the rigging slightly if storing ashore to relieve tension on the mast. 

✔ Book a professional rigging check with Peerless Marine to assess standing and running rigging condition before spring.

Local Tip: Chichester Marina can be exposed to strong winds—secure all loose lines to prevent damage.

5. Interior & electrical systems

Preventing Damp & Mould

✔ Ventilate lockers and cabins to prevent condensation. 

✔ Use moisture-absorbing crystals or dehumidifiers to reduce dampness. 

✔ Leave cushions and soft furnishings stored at home to avoid mildew.

Electronics & Batteries

✔ Turn off all electronics and disconnect batteries if storing ashore. 

✔ Check all wiring for corrosion and spray terminals with contact cleaner.

6. Mooring & security considerations

If Storing Afloat:

✔ Double up mooring lines and check for chafe points. 

✔ Use extra fenders to protect against rubbing in rough conditions. 

✔ Regularly check your yacht after storms or arrange for a local boat caretaker to monitor it.

Security Measures

✔ Remove valuables, charts, and electronics to prevent theft. 

✔ Ensure hatches and companionways are securely locked.

Local Tip: If using an outboard engine, store it securely to deter theft.

7. Final rigging & pre-spring checks

Before launching in spring, make sure: 

✅ Halyards and control lines are in good condition - replace worn ones early. 

✅ Winches, furlers, and deck gear are serviced and lubricated.

✅ Rigging is tensioned and tuned for optimal performance - this is where Peerless Marine can help!
