What's Not Covered: Yacht Hull Damage Exclusions

Yacht hull damage insurance is designed to protect your boat from physical damage, but it doesn’t cover everything. This page explains the most common exclusions in yacht hull damage policies — what your insurance won’t pay for — and how to avoid being surprised when a claim happens. You’ll learn what’s not covered, why it matters, and how to protect your boat and your wallet.

Common Hull Damage Exclusions in Yacht Insurance

What Hull Damage Insurance Covers (Briefly)

Yacht hull damage insurance, also called hull & machinery cover, typically pays to repair or replace your boat’s structure and mechanical systems if they’re damaged by covered events like collisions, fire, or storms. But there are limits — and exclusions — that define what is and isn’t covered.

Four Key Exclusions You Must Know

Here are four important exclusions that often trip up boat owners:

• Navigation Limits: Damage that happens outside the area your policy allows.
• Lay-Up Warranty: Damage that occurs when your boat is not properly secured during lay-up.
• Named-Storm Deductibles: A higher deductible that applies if damage is caused by a named storm.
• Agreed Value vs. Actual Cash Value: How much your insurer will pay if your boat is totaled.

How Navigation Limits Change Your Coverage

What Are Navigation Limits?

Navigation limits are the geographic boundaries your policy allows. If your boat is damaged outside these limits, the claim is denied. These limits are usually set by the insurer based on risk zones.

Scenario: Damage Occurs Outside Navigation Limits

You own a $500,000 yacht with a hull policy that covers the U.S. East Coast up to Florida. You take your boat to the Bahamas for a week and hit a submerged rock. The damage costs $40,000 to repair.

Because the Bahamas is outside your navigation limits, your insurer will not cover the damage. You pay the full $40,000 out of pocket.

What Happens If You Don’t Follow the Lay-Up Warranty

What Is a Lay-Up Warranty?

A lay-up warranty is a requirement in your policy that you must properly secure your boat during periods of inactivity — like winter or long-term storage. This includes things like removing fuel, draining water systems, and covering the boat.

Scenario: Boat Damages During Improper Lay-Up

Your $300,000 yacht is stored in a marina during the winter. You didn’t follow the lay-up warranty — you left fuel in the tank and didn’t winterize the engine. A freeze causes the engine block to crack, costing $25,000 to repair.

Because you didn’t follow the lay-up warranty, your insurer denies the claim. You pay the full $25,000.

Named-Storm Deductibles: What You Pay When a Hurricane Hits

What Is a Named-Storm Deductible?

A named-storm deductible is a higher percentage of your boat’s value that you must pay if damage is caused by a named storm — like a hurricane or tropical storm. This deductible is in addition to your regular deductible.

Scenario: Damage From a Named Storm

Your $600,000 yacht has a 5% named-storm deductible. A hurricane causes $70,000 in damage. Your insurer pays $67,000, and you pay the first $30,000 (5% of $600,000).

Boat Value	Named-Storm Deductible (%)	Your Payment	Insurer Pays
$600,000	5%	$30,000	$40,000

Agreed Value vs. Actual Cash Value: What You Get If Your Boat Is Totaled

What Is Agreed Value?

Agreed value is the amount you and your insurer agree your boat is worth at the start of the policy. If your boat is totaled, you get that agreed amount — no matter what it’s worth now.

What Is Actual Cash Value?

Actual cash value (ACV) is the current market value of your boat, minus depreciation. If your boat is totaled, you get what it’s worth today — which could be less than what you paid for it.

Scenario: Total Loss Under Agreed Value vs. ACV

You bought a $400,000 yacht 5 years ago. It’s now worth $250,000. You have a policy with agreed value of $350,000. A fire totals the boat.

• If you have agreed value, you get $350,000.
• If you have actual cash value, you get $250,000.

Agreed value gives you more money in a total loss — but it usually costs more in premiums.

Other Important Exclusions to Watch For

Salvage and Wreck Removal

If your boat is wrecked and needs to be removed from the water, the cost of salvage and wreck removal is often not covered by standard hull damage insurance. You may need a separate policy or endorsement for this.

General Average

General average is a maritime law concept where all shipowners share the cost of a loss if it was caused to save the ship or cargo. Most hull policies do not cover general average claims — you may need a separate policy for that.

Seaworthiness

If your boat is damaged because it wasn’t seaworthy — for example, if you ignored a maintenance issue — the claim may be denied. Insurers assume you keep your boat in good condition.

How to Avoid Being Surprised by Exclusions

Read Your Policy Carefully

Don’t just skim the fine print. Look for sections like “Exclusions,” “Conditions,” and “Warranties.” If something is unclear, ask your broker to explain it in plain language.

Review Navigation Limits and Lay-Up Requirements

Know where you can and cannot sail. If you plan to lay up your boat, make sure you follow the lay-up warranty exactly — even small mistakes can lead to denied claims.

Understand Your Deductibles

Know what your regular deductible is and what the named-storm deductible is. If you live in a hurricane-prone area, this can be a big part of your out-of-pocket costs.

Choose Agreed Value If You Can Afford It

If you want more protection in a total loss, agreed value gives you peace of mind. But it costs more — weigh the cost against the benefit.

Final Takeaway

Yacht hull damage insurance is essential, but it’s not a magic shield. You need to understand what it covers — and what it doesn’t. Read your policy, follow the rules, and plan for the worst. The more you know, the better you’ll be protected — and the less you’ll pay when the unexpected happens.
