Ask a handful of boat owners on Lake Murray how they picked their insurance and most will tell you the same thing: they went with the cheapest quote. That makes sense. A boat policy is easy to ignore until the day you need it, and by then the fine print has already decided what you get paid.

We're an independent agency based in Lexington, and we quote boat coverage with several carriers. The gap between policies is bigger than most people expect. Two quotes can come in $50 apart and pay out thousands of dollars apart on the same claim. Here's what to line up side by side before you pick one.

The short answer

When you compare boat insurance in South Carolina, look at these 11 things, roughly in this order:

1. Liability limits
2. How the boat is valued (agreed value, actual cash value, or replacement cost)
3. Deductibles, including any named-storm deductible
4. Which perils are covered and which are excluded
5. Navigation area and usage limits
6. Lay-up rules
7. Trailer, gear, and electronics coverage
8. Uninsured boater coverage
9. Towing and on-water assistance
10. Discounts
11. Claims service and whether the carrier specializes in boats

Premium matters, but it belongs at the end of the list, not the top.

1. Liability limits

Liability is the part of the policy that pays when you hurt someone or damage their property. On a busy summer weekend at Lake Murray or Lake Wateree, that could be a collision with another boat, a wake that swamps a pontoon, or a guest who gets hurt climbing back aboard.

The South Carolina Department of Insurance lists liability for injuries on your boat and damage to other people's property as a core part of a boat policy. The question is how much. A serious injury claim can run well past $100,000. If you carry a personal umbrella policy, check what watercraft liability limit the umbrella carrier requires underneath it. Most want a specific minimum, and falling short can leave a gap right where you least want one.

2. How the boat gets paid for if it's totaled

This is the single biggest difference between policies, and it's the one people skip. The SC Department of Insurance describes three ways a boat can be valued:

• Actual cash value (ACV) pays what the boat is worth today, minus depreciation and your deductible.
• Agreed value pays an amount you and the insurer settle on up front if the boat is a total loss.
• Replacement cost pays to replace the boat with one as similar as possible.

Here's why it matters. Say you bought a bass boat for $45,000 six years ago. On an ACV policy, a total loss pays today's depreciated value, which could be a lot less than you expect. On an agreed value policy, the number was set when you bought the coverage. Agreed value usually costs more, and for a newer or well-kept boat it's often worth it.

3. Deductibles

Look at the deductible amount and how it's figured. Some policies use a flat dollar amount. Others use a percentage of the boat's insured value, which can climb fast on an expensive boat.

If you keep your boat on the coast, ask whether the policy has a separate named-storm or hurricane deductible. Some do, and it can be much higher than the regular deductible. Also ask whether the policy pays anything toward hauling the boat out ahead of a storm.

4. What's covered and what isn't

Most boat policies cover the big events: theft, fire, collision, sinking, and storm damage. The exclusions are where policies really differ. Common ones include wear and tear, mechanical breakdown, marine growth, and damage from ice or freezing. Some carriers offer add-ons for things like mechanical breakdown on newer engines.

Read the exclusions page, or have your agent walk you through it. It's the fastest way to see the real difference between two quotes.

5. Navigation area and how you use the boat

Every boat policy has limits on where the boat is covered. A policy written for a lake boat may not cover you in the Intracoastal Waterway or offshore. If you trailer your boat from the Midlands down to Charleston or Georgetown, or take it offshore to fish, make sure the navigation area on the policy matches how you actually use it.

Ask about other usage limits too: nighttime operation, maximum horsepower, and whether renting the boat out or taking paying passengers is excluded. For personal policies, it almost always is.

6. Lay-up rules

Some policies suspend or reduce coverage during months when the boat is supposed to be out of the water. The SC Department of Insurance warns that some watercraft policies are suspended during off months, and some have premiums that are fully earned (meaning no refund if you cancel early).

Lots of South Carolina boaters use their boats year-round. If you're out on the lake in January chasing stripers, make sure your policy doesn't think your boat is on blocks.

7. Trailer, gear, and electronics

Your trailer, fishing gear, electronics, and safety equipment may be covered, covered with low limits, or not covered at all. Check each one.

The trailer is worth a closer look. South Carolina doesn't require a title or registration for privately owned boat trailers under 2,500 pounds empty, so a lot of people forget the trailer exists when they buy coverage. Your auto policy may only give you liability while you're towing, not physical damage to the trailer itself.

For tournament anglers, a good set of electronics can be worth more than some boats. Make sure the policy limit for equipment is high enough to replace yours.

8. Uninsured boater coverage

South Carolina requires uninsured motorist coverage on car insurance. Boat policies are separate, and uninsured boater coverage is usually optional. Plenty of boats on the water carry no insurance at all, since the state doesn't require it. If one of them hits you, this coverage helps pay for your injuries. It's usually inexpensive. Ask for it.

9. Towing and on-water assistance

Running out of gas or losing an engine in the middle of the lake is a common problem, and a tow can be expensive. Some policies include towing and assistance, some offer it as an add-on, and some leave it out. If you already pay for a separate towing membership, you may not need both.

10. Discounts

Ask about discounts for:

• Completing a boater safety course
• Years of boating experience
• A claims-free history
• Bundling with your home or auto policy
• Safety and anti-theft equipment
• Secure storage

The SC Department of Insurance recommends checking rates, discounts, and safety guidelines with the insurer before you buy.

11. Claims service and specialization

Price and coverage are only half of it. The other half is how the company treats you when something goes wrong. The SC Department of Insurance suggests comparing customer service and quality along with price and coverage, and getting quotes from more than one company.

Carriers that specialize in boats tend to understand marine claims better. They know what a salvage operation costs, how to value a custom build, and how to handle a boat that sank at the dock. That's worth something.

Your homeowners policy probably isn't enough

A lot of people assume their homeowners policy covers the boat. It might, but only a little. The SC Department of Insurance notes that homeowners coverage may only extend to a small boat, and the liability protection is limited. A kayak or a small jon boat might be fine. A bass boat, pontoon, or wake boat almost certainly needs its own policy.

Does South Carolina require boat insurance?

No. SCDNR says state registration laws don't require proof of insurance to register a boat in South Carolina. That doesn't mean you don't need it. If you financed the boat, your lender will almost certainly require coverage. Many marinas and storage facilities require liability coverage too. Even without either of those, one bad accident can put your savings at risk.

Frequently asked questions

What is the best boat insurance in South Carolina? There isn't one best company for everyone. The right policy depends on your boat's value, where you use it, and how much risk you want to carry. Compare valuation method, liability limits, and navigation area before you compare price.

Is boat insurance required in South Carolina? No. The state doesn't require proof of insurance to register a boat. Lenders and many marinas do require it.

Is agreed value better than actual cash value? For a newer or well-maintained boat, agreed value usually pays out much better on a total loss. It typically costs more. ACV can make sense for an older boat with a low market value.

Does my homeowners insurance cover my boat? Possibly a small boat, with limited liability. Larger boats almost always need a separate policy.

Does boat insurance cover my trailer? Sometimes. Check the policy. Your auto policy may only cover liability while towing.

Will my policy cover me in the ocean if I usually boat on Lake Murray? Only if the navigation area on your policy includes coastal or offshore waters. Ask before you head to the coast.

What's a lay-up period? A stretch of months when the policy assumes the boat is out of the water. Coverage may be reduced or suspended during that time.

How can I lower my boat insurance premium? Take a boater safety course, bundle with your home or auto policy, keep a clean claims history, and consider a higher deductible if you can afford it.
