How to Insure a Boat or Watercraft in Minnesota

It's June on Minnesota's lakes and a lot of people are back on the water. It's also the time of year when I have the most conversations about boat insurance — sometimes because someone just bought something new, and sometimes because someone just had a claim and realized their coverage wasn't what they thought.

The most common problem we see isn't that people have no insurance — it's that they're underinsured. Boat values climbed significantly after 2020 and haven't fully come back down. A pontoon that was worth $35,000 when it was insured four years ago might be worth $50,000 or more today. If the insured value hasn't been updated, a total loss doesn't come close to replacing it.

Does Your Homeowners Policy Cover Your Boat?

For a basic canoe, kayak, or small aluminum fishing boat with a low-horsepower motor, your homeowners policy may offer some coverage — typically up to about $1,500 in hull value as personal property, with limited liability. That's it.

For anything beyond that — a pontoon, a fishing boat with a real outboard, a ski boat, a wakeboard boat, a jet ski — your homeowners policy is not adequate coverage. The hull value is likely well above the personal property sub-limit, and the liability exposure on the water is real and not covered under your home policy at any meaningful level. A dedicated watercraft policy is the right fit.

What a Watercraft Policy Actually Covers

A standalone boat or watercraft policy typically covers:

• Hull and motor (physical damage) — theft, collision, fire, sinking, windstorm, and other covered perils. This is the core coverage and where the value question matters most.
• Liability — bodily injury and property damage you cause to others on the water. If you hit another boat on Leech Lake or Mille Lacs and injure someone, liability covers your legal costs and the judgment up to your policy limit.
• Medical payments — covers medical expenses for you and your passengers after a boating accident, regardless of fault.
• Uninsured boater — the watercraft equivalent of UM/UIM auto coverage. If someone hits your boat and has no insurance, this pays.
• Towing and assistance — on-water towing if your engine dies or you run aground. On a busy summer weekend on Gull Lake, a tow isn't cheap.
• Trailer coverage — the boat while it's on the trailer in transit, at a launch, or in storage.

The Hull Value Problem — and Why It Matters Right Now

Boat values surged during and after the pandemic, driven by the same supply constraints and demand spikes that hit the auto market. A lot of pontoon and fishing boat owners who bought or insured their boats in 2018 or 2019 are now carrying insured values that significantly lag what their boat would cost to replace.

Here's what that looks like in practice: a client's pontoon — insured for $32,000 based on what it was worth at purchase — was stolen from a marina storage facility over the winter. Clean theft, no recovery. The claim comes in and the payout is based on the insured value, less depreciation under an actual cash value policy. The owner goes to replace the boat and finds comparable models running $48,000–$52,000. The gap comes out of their pocket.

Agreed value vs. actual cash value

Agreed value means your insurer agrees up front to pay a specific dollar amount in the event of a total loss — no depreciation applied. If your boat is totaled or stolen and your agreed value is $48,000, you receive $48,000.

Actual cash value (ACV) pays what the boat is worth at the time of the claim, after depreciation. The insurer's adjuster determines current market value based on age, condition, and comparable sales. On a five-year-old boat, the ACV payout can be meaningfully lower than replacement cost.

For newer or higher-value boats, agreed value is almost always the better choice. The premium difference is usually modest. Ask your agent which basis your current policy uses.

Liability on the Water

Minnesota lakes get busy, especially on summer weekends. Lake Minnetonka, Gull Lake, Leech Lake, Mille Lacs — the traffic on a Saturday afternoon in July is real, and so is the liability exposure. A collision at speed, someone injured falling off a tube, a swimmer struck by a propeller — these are scenarios where liability limits matter.

Most watercraft policies start at $100,000 in liability coverage, with options to increase to $300,000 or more. For boats used regularly on busier lakes, or boats that pull riders at speed, $100,000 isn't a lot. An umbrella policy can sit above your watercraft liability limit the same way it sits above your auto and home limits — giving you broader protection without dramatically increasing the premium on the watercraft policy itself.

Personal Watercraft — A Note on PWC

Jet skis and other personal watercraft are covered under a watercraft policy, but they typically carry higher rates than boats of comparable value. The loss history on PWC is worse — they're faster, easier to operate without experience, and involved in more accidents per hour of use than most boats. Some carriers won't write PWC at all, or will exclude certain models or high-horsepower units.

If you have a jet ski, tell your agent specifically and confirm you have dedicated coverage. Don't assume a general watercraft policy automatically covers it on the same terms as your boat.

Winter Storage and the Theft Window

Most Minnesota boat theft happens in the off-season — October through April, when boats are sitting in storage facilities or on lifts at closed-up cabins. It's not glamorous, but a boat locked to a trailer at a storage lot for six months is a more accessible target than the same boat in the water at a busy marina in July.

Your watercraft policy covers theft year-round, not just during boating season. If you're storing your boat at a facility that doesn't have great security, that's worth factoring into your coverage decision. And if the boat is stored at your cabin — whether covered or not — confirm your watercraft policy covers it at that location.

What Watercraft Insurance Costs in Minnesota

Annual premiums vary by boat type, value, coverage limits, and how you use it — whether it's primarily lake cruising, pulling riders at speed, or sitting on a lift most of the season. Rough ranges:

These are starting-point ranges for full coverage including liability. Agreed value, higher liability limits, and uninsured boater coverage all add to the premium — usually modestly. Getting a quote is the only way to know what your specific boat costs to insure properly.
