Boat Insurance Explained: Agreed Value vs. Actual Cash Value
Boat insurance is easy to put off until you need it. When you do need it, the details matter a lot, especially how a total loss would be paid. This guide explains the main types of coverage, the difference between agreed value and actual cash value, and the fine print worth checking before you buy. It draws mainly on consumer guides published by two state insurance regulators, Maryland and Michigan.
Do you have to insure your boat?
It depends on where you live and how you finance and store the boat. Maryland's Insurance Administration, for example, says Maryland has no law requiring boat insurance, though it still recommends coverage. Even where the law doesn't require it:
- Lenders often do. If you finance, the lender will usually require insurance that protects its interest in the boat.
- Marinas may require liability coverage before you rent a slip. Ask yours.
Watch out for "force-placed" insurance. Maryland's guide warns that if you let required coverage lapse, a lender can buy a policy that protects only the lender and add the premium to your loan payment. In a total loss, the lender is paid what's still owed on the loan, but you get nothing for your equity. You avoid this by keeping your own policy in force with the lender named on it.
Three ways to get coverage
According to the Maryland guide, you can usually insure a boat in one of three ways:
- Your homeowners policy. It may give some coverage for small boats, such as sailboats under 26 feet or powerboats with outboards under 25 horsepower. That coverage can be very limited; the Maryland guide gives the example of property damage capped at $1,000 for the boat, trailer, equipment and motor combined.
- A watercraft endorsement added to your homeowners policy, for an extra premium. It can cover larger boats than the base policy.
- A separate boat owners policy. These tend to give broader coverage for the boat, its equipment and the trailer.
Michigan's Department of Insurance and Financial Services adds that a homeowners policy may only cover a boat in specified waterways. It also notes that a boat claim on your homeowners policy could affect that policy's premium, which is one reason to consider a separate boat policy.
What a boat owners policy typically covers
Policies differ, but the Maryland guide describes common parts:
- Physical damage to the boat, motor, equipment and trailer, often on an "all risks unless excluded" basis.
- Liability: if you're legally responsible for injuring someone or damaging their property while operating the boat.
- Medical payments: often covering you, your family and guests in, on, or getting on and off the boat.
- Optional extras: emergency services, towing, wreck removal, personal effects and similar.
"Boat equipment" varies by policy. Maryland lists items often included, such as anchors, batteries, bilge pumps, life jackets, depth finders, radios and covers, but your policy may not include all of them. Read the definition.
Common exclusions listed by Maryland include:
- wear and tear, rust, corrosion, mold and rot;
- mechanical or electrical breakdown;
- freeze damage, unless you took reasonable care to winterize (see our Winterizing guide);
- damage during racing or speed contests;
- neglect;
- business use.
Agreed value vs. actual cash value
This is the big decision. Both state guides describe the options the same way.
Actual cash value (ACV)
ACV pays what it would cost to replace the boat, minus depreciation. Michigan notes ACV policies are generally less expensive, but because depreciation is taken off, a total-loss payout on an older boat can be well below what you paid or owe.
Agreed value (sometimes "stated value")
With agreed value, you and the insurer agree on the boat's value when the policy is written. If the boat is destroyed by a covered loss, you receive that agreed amount. Michigan notes these policies tend to cost more, but depreciation isn't deducted when a total loss is settled. Insurers may ask for a survey or other proof of value before agreeing on a figure. See our Marine Surveys guide.
Replacement cost
Some policies offer replacement cost value. Maryland describes it as paying to replace the boat with one of like kind and quality.
Which is right for you?
- If you financed a newer boat, agreed value can help make sure a total loss pays enough to clear the loan.
- On an older, inexpensive boat, ACV may be fine, and cheaper.
- Ask how partial losses are handled. The definitions above describe total losses, and partial losses can work differently. Allstate, for example, describes a repair-cost option for partial losses.
Several major insurers in our data offer both approaches. BoatUS (underwritten by GEICO Marine) offers "Agreed Hull Value" on most boat types other than PWC, or ACV. Progressive, Allstate and Travelers list agreed value or ACV options. Chubb's and Hagerty's programs are built around agreed value.
As Maryland's guide puts it, the method matters because different methods can pay you different amounts for the same damage, and your policy will say which method applies. Check before you have a claim.
Fine print worth checking
- Navigation limits. Maryland warns that some policies limit coverage to certain waters, such as the Chesapeake Bay or inland rivers. Taking the boat outside those waters may void coverage. Tell your insurer before you trailer to new waters or head offshore.
- Storage periods. Ask whether the policy has any terms for the months the boat is laid up, and what's covered while it's stored.
- Cancellation terms. Maryland notes that many boat policies have strict cancellation rules. Some are "fully earned" at the start, so you get no refund if you cancel, and others apply a short-rate penalty. This partly discourages insuring only during the season.
- Deductibles. Ask whether any losses carry a separate or higher deductible.
- Credit card fees. Maryland notes that agents may charge the actual cost of taking a card payment, if they disclose it.
What affects your premium
The Maryland guide lists common rating factors:
- the boat's type and length;
- motor type and horsepower;
- the boat's age, value and condition;
- how and where you use it, and where it's kept;
- your driving record, boating experience and claims history;
- your deductible.
Ways to lower your premium suggested in the same guide:
- choosing a higher deductible;
- taking boating safety courses (see Boater Education by State);
- keeping a clean driving record and the boat in good condition;
- staying claims-free;
- carrying Coast Guard-approved fire extinguishers and a ship-to-shore radio;
- asking about multi-policy discounts.
If you can't find coverage
Older or unusual boats, poor records or high-risk waters can make coverage hard to find. Maryland explains that you may then need a surplus lines insurer through a specialized broker. In Maryland, you generally must first be turned down by three authorized insurers. Surplus lines carriers aren't regulated the same way, so check the broker's license with your state insurance department first.
Building insurance into your budget
Insurance premiums vary too much by boat, person and location for us to show a typical figure. We don't publish an "average premium" because we haven't found an official source for one. Get real quotes and enter your premium in the True Cost tool to see your full annual cost. Our State Rules tool covers each state's registration and tax rules, which are separate from insurance.
