Boat Insurance Calculator: How Much to Insure Your Boat For

Boat value and deductible calculator

Enter the replacement value of each part of your boat package and an optional deductible.

Arithmetic only. This calculator works only with the figures you enter. It is not a quote and does not predict what any insurer will charge.

Agreed value vs. actual cash value

An agreed value policy sets the boat's value when you buy the policy and pays that amount, minus the deductible, after a covered total loss. An actual cash value policy pays the boat's depreciated value at the time of the loss. Agreed value usually costs more but removes uncertainty, which matters for newer boats.

Use the calculator's total as a starting point when you discuss an agreed value with an insurer, and keep receipts and photos for equipment and electronics.

Percentage deductibles on boats

Some boat policies set the hull deductible as a percentage of the insured value, often with a minimum dollar amount. A 1 or 2 percent deductible on a high-value boat can be larger than you expect, so convert it to dollars before you compare quotes.

Boat coverages to compare

Availability varies by insurer.

Why homeowners insurance is not enough

Homeowners policies often cover only small boats, such as canoes, kayaks, or boats with low horsepower, and usually include little or no liability for boating accidents. A dedicated boat policy covers the hull, motor, trailer, equipment, liability, uninsured boaters, and on-water towing.

What affects boat insurance prices

• Boat type, length, age, and value.
• Horsepower and top speed.
• Navigation territory and ocean use.
• Operator experience and boating safety courses.
• Storage location, including dry storage or a marina slip.
• Deductibles and agreed value or actual cash value settlement.

Liability, medical payments, and uninsured boaters

Liability is often the most important part of a boat policy. Boating accidents can injure passengers, swimmers, water skiers, and people on other boats, and can damage docks and other vessels. Many boaters choose liability limits of $300,000 or more and add an umbrella policy, confirming that the umbrella covers watercraft of their size and horsepower.

Medical payments coverage pays medical bills for you and your passengers regardless of fault, and uninsured boater coverage helps when an at-fault boater has no insurance, which is common since most states do not require boat insurance.

Boat types and coverage considerations

General descriptions. Policy forms vary by insurer.

Coverages worth adding

• Fuel spill liability. Covers cleanup costs and liability under environmental laws.
• Wreck removal. Pays to remove a sunken or damaged boat when required.
• On-water towing. Pays for assistance when you break down or run aground.
• Personal effects. Covers fishing gear, water sports equipment, and personal items.
• Trailer coverage. Covers the boat trailer, which may not be covered by your auto policy.
• Hurricane haul-out. Pays part of the cost to move a boat ahead of a named storm in coastal areas.

Ways to save on boat insurance

• Take an approved boating safety course, which some insurers reward with a discount.
• Choose a higher deductible you can afford.
• Store the boat in dry storage or a secure marina.
• Bundle boat insurance with auto or home where it lowers the total.
• Ask about lay-up periods if you boat only part of the year.
• Install anti-theft devices and keep maintenance records.

Questions to ask before you buy

• Is the policy agreed value or actual cash value?
• What is the navigation territory, and are ocean trips covered?
• Is there coverage in Mexican waters with a separate Mexican policy?
• Are fuel spill, wreck removal, and towing included?
• How are the trailer and personal effects covered?
• Are there operator age or experience requirements?
• Does my umbrella cover this boat?

Seasonal use and storage

Some boaters use their boats year-round, while others store them for months. Ask whether the policy offers a lay-up period that reduces premium while keeping coverage for theft, fire, and storm damage in storage. Boats kept in the water at a marina face different risks, such as sinking, dock fires, and collisions with other vessels, than boats stored on trailers or in dry stack storage.

If you store a boat at home, check whether your homeowners association allows it and whether your trailer and boat are secured against theft.

Buying or financing a boat

Before buying a used boat, get a marine survey for larger or older boats, since many insurers require one to set an agreed value. Confirm the boat's hull identification number, registration, and title history, and arrange coverage before you take possession, especially if you will tow it home or launch it right away.

If you finance the boat, the lender will usually require physical damage coverage, list itself as loss payee, and set a maximum deductible. Keep proof of coverage current to avoid force-placed insurance.

Choosing coverage amounts

When choosing coverage amounts, start with the boat's replacement or agreed value, then add the value of electronics, fishing gear, and water sports equipment. Choose liability limits that reflect who rides with you and where you boat; carrying friends, guests, or towed skiers raises the potential for serious injury claims.

Review coverage each year. Boat values change, equipment is added, and your plans may shift from lakes to ocean waters or to longer trips that need a broader navigation territory.

How an independent agent helps

An independent agency can compare boat policies from several insurers it represents, including specialty marine insurers that may not sell directly. That helps when your boat is older, high-performance, or used in ocean waters, since insurers differ widely in what they will accept and how they value boats.

If you also own an RV, personal watercraft, motorcycle, or other recreational vehicles, ask about bundling them with one insurer. A single renewal date and multi-policy discounts can simplify things, but compare the total cost and coverage against separate policies before you switch. Keep a list of every vessel and trailer, with values and serial numbers, so each one is scheduled correctly.

Records to keep

• Declarations page and policy forms.
• Registration and California Boater Card for each operator.
• Marine survey and photos of the boat and equipment.
• Receipts for electronics, upgrades, and repairs.
• Marina or storage agreements and any insurance requirements they set.

What to do after a boating accident

• Make sure everyone is safe and call for help if needed.
• Report accidents to authorities as your state requires.
• Prevent further damage and keep receipts.
• Photograph damage and gather witness information.
• Notify your insurer promptly.

Switching insurers without a gap

If a new quote is lower, switch carefully so you are never uninsured:

1. Confirm the final price after the insurer verifies your information.
2. Set the new policy to start on or before the date the old one ends.
3. Give the new insurer your lender or lessor information if the vehicle is financed.
4. Save your new ID cards and declarations page.
5. Cancel the old policy effective the same day, and ask about any refund of unused premium.
6. If you have an SR-22, confirm the new insurer files it before the old filing ends.

How to verify an insurer or agency

Before buying through any website or app, confirm who is selling you the policy and who will issue it:

1. Find the licensed agency or insurer named in the site's footer, terms, or license page.
2. Look up the agency or producer on your state insurance department's license search, or through the National Insurance Producer Registry (NIPR).
3. Look up the insurer on your state insurance department's company search to confirm it is authorized in your state.
4. Save the insurer's name and policy number once issued, since that is who handles claims.

A legitimate service will make this information easy to find. Be cautious if you cannot identify the licensed entity.

When an agent may help

Online tools work well for simple situations. A conversation with a licensed agent may be more useful when:

• You have a teen driver, several vehicles, or drivers with recent accidents or violations.
• You need an SR-22 or other state filing. See our SR-22 insurance page.
• You use a vehicle for rideshare, delivery, or other business purposes.
• You own a home, rental property, or significant savings and want liability limits that work with an umbrella policy.
• You have had a claim denied or a policy nonrenewed and need help understanding your options.

An agent can also explain differences in policy wording that are hard to see on a results page.

How to check any insurer

Before you buy from any company, take a few minutes to check it:

• License. Confirm the insurer is licensed in your state through the state insurance department's company lookup.
• Complaints. The NAIC's Consumer Insurance Search shows complaint counts and a complaint index for each company, where 1.00 is the expected level for the company's size.
• Financial strength. Ratings from agencies such as A.M. Best describe an insurer's ability to pay claims.
• Legal name on the quote. Large groups write policies through several companies with different rates and rules. Make sure you know which one issues your policy.
• Claims process. Ask how claims are reported, whether there is a preferred repair-shop program, and how quickly adjusters respond after storms.
