Protecting your boat from winter storms: 9 practical checks

A winter storm often gives warning before conditions on the dock become dangerous. That is the time to assess the preparation of your boat, not when the wind is already picking up. With these nine checks, you can systematically inspect the mooring, mooring lines, and loose equipment. Every boat and marina requires an appropriate approach: if in doubt, coordinate the mooring situation with the harbor master.

1. Assess the mooring together with the marina

A sheltered box, a fixed quay, and a floating dock respond differently to wind and changes in water level. Ask what you need to take into account at your mooring. Also discuss who will keep watch when you are away for an extended period. Do not use a different mooring yourself without consulting the marina.

2. Check the mooring lines along their entire length

Inspect mooring lines for fraying, damage, and wear at eyes, knots, and contact points. Also pay attention to parts that remain out of sight during normal use. A line that still looks good in one place is not automatically reliable everywhere. If in doubt, have it assessed whether replacement is necessary.

For example, consider Talamex polyester mooring lines or a Landvast deluxe with eye. Choose the length, version, and strength based on your boat, the mooring, and the use. A single fixed diameter is not suitable advice for all boats.

3. Check the entire mooring system

It is not just the rope that counts: attachment points and the distribution of loads also deserve attention. Check accessible bollards, mooring posts, and cleats for visible damage or play. Have uncertain attachments assessed. Do not simply tighten all lines; the mooring system must appropriately handle the movement of the boat and water level. Ask the harbor master for advice on your situation.

4. Prevent chafing at contact points

Where a line runs along an edge, eye, or fitting, friction can cause wear. Therefore, inspect the path of each line and check it after changes in wind direction or water level, as soon as it is safe to do so. Suitable line protection can help, but does not make a poor line path or damaged attachment point safe.

5. Place fenders where actual contact can occur

Check that fenders protect the boat in the right places and are properly secured. Their position must suit the hull, dock, and expected movement. A fender hanging above the contact point does not help there. Also check the condition of fender lines and any fender accessories. Coordinate additional protection with the mooring instead of randomly hanging up more fenders.

6. Store loose items and wind catchers

Remove loose cushions, buckets, and other equipment from the deck and store them dry and securely. Assess how a bimini, loose cover, or other fabric structure should be stored according to the manufacturer. Reduce loose parts that can rattle or blow away wherever possible. Do not climb on slippery or hard-to-reach parts when conditions are unsafe.

7. Check the cover, cockpit tent, and water drainage

A suitable cover must be properly supported and secured according to the instructions. Prevent rainwater from forming heavy pockets. Check that fasteners do not rub against paint, windows, or delicate fittings. Keep ventilation open and clear cockpit drains of leaves and dirt. A taut-looking sail is no guarantee that water drains away properly.

8. Check necessary systems and cables

Check which systems need to remain operational during your absence, such as a bilge pump or security system. For bilge pumps, follow the prescribed inspection and testing procedure; do not change connections or settings without reason. Also check the condition and position of shore power cables. Do not use damaged connections and have ambiguities in the electrical installation assessed by an expert.

9. Arrange supervision before and after stormy weather

Make sure the marina has up-to-date contact details and agree on who will check your boat. After a storm, check for shifted fenders, chafing marks, water ingress, and loose covers, but only as soon as the marina and dock are safely accessible. In case of immediate danger, personal safety takes precedence over saving belongings. Follow the instructions of the marina and emergency services.

Is your boat on its side?

Then other points of attention apply. Let the storage facility handle the support and positioning. Do not move or adjust stands, supports, or tensioning devices yourself. Discuss the cover and wind load in advance with the responsible storage facility and follow their instructions.

Prepare well for the winter harbor

A check before bad weather is more valuable than improvising during the storm. View anchoring and mooring at Bootland for mooring lines, fenders, and suitable aids. Always combine product choice with a mooring plan that suits your boat and marina.
