Boats are expensive to buy, expensive to repair, and easy to damage — one bad storm, one submerged log, or one grounding can turn a weekend on the water into a five-figure bill. Boat insurance exists to absorb that shock, but many owners have no idea what a policy should cost or what it actually covers.
The short answer: a typical recreational boat policy costs roughly $200 to $500 a year for a smaller boat, and $500 to $1,500 or more a year for larger, faster, or more valuable vessels. Your exact premium depends on the boat's value, horsepower, where you keep it, and how you use it. Here's how it all breaks down.

What boat insurance costs on average
As a rough guide, expect to pay around 1% to 2% of your boat's value per year in premiums. A small fishing boat or runabout worth $10,000 might cost roughly $150 to $300 a year to insure. A mid-range bowrider or pontoon worth $40,000 to $60,000 typically runs $400 to $900 a year. Larger cruisers, yachts, and high-performance boats worth $100,000 or more commonly cost $1,000 to $2,500 a year, and sometimes more.
Liability-only cover is cheaper — often $100 to $300 a year — because it skips physical damage cover for your own boat. It's a common choice for older, lower-value boats where full cover would cost more than the boat is worth.
What a boat policy covers
A standard boat policy bundles several protections. Physical damage covers your hull, motor, and equipment against collision, sinking, fire, theft, vandalism, and storm damage. Liability pays for injuries or property damage you cause to others — for example, if you collide with another boat or a dock. Medical payments cover injuries to you and your passengers, regardless of fault.
Many policies also include uninsured boater cover (for accidents caused by someone with no insurance), towing and assistance on the water, and cover for personal effects and fishing gear on board. Some include hurricane haul-out cover, which reimburses part of the cost of pulling your boat out of the water ahead of a named storm — a useful feature in hurricane-prone states (see our guide to flood insurance costs in Florida).
Common exclusions include wear and tear, gradual deterioration, damage from a lack of maintenance, and — on many policies — use of the boat for racing or commercial charters. Read the exclusions before you buy, not after a claim.
What affects your premium
- Boat value and type — bigger, faster, and more expensive boats cost more to insure. High-horsepower speedboats are among the priciest.
- Where you boat and store it — hurricane zones, high-theft areas, and year-round in-water storage all push premiums up. Indoor or trailered storage usually earns a discount.
- Your boating record — accidents, claims, and boating-under-the-influence violations raise rates, just like a driving record does for cars.
- Experience and safety courses — a completed boating safety course can cut your premium, and insurers often ask how many years you've operated similar boats.
- Navigation area — coastal and offshore use costs more than inland lakes and rivers.
- Deductible — a higher deductible lowers your premium, but means more out of pocket on a claim.
Is boat insurance legally required?
Most US states do not legally require boat insurance for private recreational use — but there are important exceptions. If you financed your boat, your lender will almost certainly require full cover until the loan is paid off (similar to how gap insurance relates to financed vehicles). Many marinas also require proof of liability cover before they will rent you a slip, and some states require liability insurance for certain boat types or horsepower levels.
Even where it is not required, going without cover is risky: a single serious liability claim can run into hundreds of thousands of dollars.
How to lower your premium
- Take a boating safety course — many insurers offer a discount of 5% to 15%.
- Store the boat securely — indoor storage, a locked facility, or a trailer at home beats an open marina slip.
- Raise your deductible — if you can comfortably cover a $1,000 deductible, it can noticeably cut the annual premium.
- Bundle with home or auto — multi-policy discounts are common.
- Ask about layup periods — if you only boat part of the year, some policies offer reduced rates for months the boat is out of the water.
- Keep a clean record — avoiding claims and violations is the biggest long-term lever on price.
Frequently asked questions
How much is boat insurance per month?
For a typical small to mid-size recreational boat, roughly $20 to $60 a month. Larger or high-performance boats can run $100 a month or more. Most insurers bill annually, with monthly payment plans often available for a small fee.
Does boat insurance cover engine breakdowns?
Generally no — mechanical breakdown and wear are excluded. However, if a covered event (like striking a submerged object) damages the engine, that damage is usually covered. Some insurers sell mechanical breakdown add-ons.
Do I need insurance for a small boat or jet ski?
Personal watercraft like jet skis are usually insured under their own policies, typically costing a few hundred dollars a year. Even small boats benefit from liability cover — an accident on the water can be expensive regardless of boat size.
What is agreed value vs. actual cash value?
Agreed value pays the amount written in the policy if the boat is a total loss, with no depreciation deduction. Actual cash value pays the boat's current market value, which falls over time. Agreed value costs more but gives far more certainty on a total loss.
