Boat Insurance and Winterization — What Most Policies Actually Require

Before you store your boat for the winter, it's worth knowing how your insurance treats freeze damage. This page is general information, not a guarantee or insurance advice — check your own policy — but the pattern across the industry is consistent and worth understanding.

Many policies exclude freeze damage unless a pro winterized the boat

A cracked block or split manifold from freezing is one of the most common and expensive off-season losses — and a lot of marine policies will only pay that claim if you can show the boat was professionally winterized, often with a receipt or documentation from a qualified shop. DIY winterization, or no winterization at all, is a common reason these claims get denied. Policies vary, so read yours or ask your agent.

Why documented, careful winterization matters

This is exactly why we take winterization so seriously and document every step. When our techs winterize your boat, you get a clear record of the work performed — fogging, full block/manifold/pump drain, oil and filter change, battery storage — that you can keep with your records. We won't make promises about the weather or your specific policy, but careful, documented professional winterization is what most insurers are looking for.

The easiest way to be covered and carefree

Our all-inclusive Boat Concierge includes careful, documented winterization as part of the package — we pick the boat up, winterize and store it, detail it, and bring it back in spring with a full tank. One call, fully handled, fully documented.
