Why Should I Insure My Boat During the Winter?

Learn why keeping boat insurance year-round can help protect your investment.

Many boaters think insurance is only necessary during the boating season, when the vessel is in the water. But risks don’t hibernate when your boat does. Winter brings its own challenges — from ice and freeze damage to theft and vandalism. Even in storage, your boat remains an investment worth protecting.

Coverage needs vary by insurer and location. Always confirm details with your provider before relying on coverage.

Risks Boats Face in the Winter

Even when your boat is stored on land or under cover, it’s not risk-free. Here are some of the most common winter threats:

Ice and Freeze Damage  

If not properly winterized, freezing temperatures can crack engines, damage plumbing, and destroy fittings. Some policies may help cover freeze-related claims, subject to proper winterization and policy terms.

Storm Damage

Snow, ice, and winter storms can damage tarps, structures, or even topple stored boats.

Theft

Winter storage lots or driveways can be targets for thieves, especially for outboard motors, electronics, or trailers.

Vandalism

Boats left unattended for months are vulnerable to vandalism or break-ins.

Fire

Indoor storage facilities carry their own risks, such as electrical fires.

Why Keep Insurance Year-Round?

Lender and Marina Requirements

If your boat is financed or stored at a facility, continuous coverage is often required. Lapses could put you in breach of your loan terms or marina agreement.

Coverage for the Unexpected

Insurance isn’t just for when the boat is on the water. Comprehensive coverage may extend protection to winter-specific risks, so you’re not left paying out-of-pocket for costly damage.

Protecting Your Investment

Boats are expensive assets. Carrying year-round insurance means your investment remains protected against loss, even during months you’re not actively using it.

Peace of Mind

Knowing your boat is insured through winter lets you focus on planning next season instead of worrying about what could happen in storage.

Tips to Reduce Winter Risk

Winterize properly

Drain water systems, add antifreeze, and prep the engine.

Use secure storage

Indoor or covered storage reduces exposure to weather.

Add theft deterrents

Locks, alarms, or removing high-value electronics can help.

Check with your provider

Confirm whether freeze damage, vandalism, or storage-related losses are included in your coverage.

Final Thoughts

Winter might seem like a safe time to pause coverage, but the season comes with its own risks. Keeping your boat insured through the off-season may help protect against theft, storm damage, freeze-related issues, and more.
