Hull Insurance vs Agreed Value Explained

When you're insuring your boat or yacht, you'll often see two terms: "hull insurance" and "agreed value." Here's the short version: **hull insurance** is the type of coverage that protects the physical structure of your boat, while **agreed value** is a specific way of setting the payout amount in case your boat is damaged or destroyed. The key difference is that **agreed value locks in a set payout amount when you buy the policy**, while **actual cash value (ACV)**, the alternative, bases the payout on the boat’s current market value at the time of the claim — which can be lower than what you expect.

What Is Hull Insurance?

Hull insurance is the part of your boat insurance policy that covers physical damage to your boat. This includes damage from collisions, storms, fires, or theft. It's often called "hull and machinery" cover in more technical terms, but you can think of it as the insurance that keeps your boat in good shape — or pays to fix it if it isn't.

What Hull Insurance Typically Covers

• Collision damage: If you hit a dock, another boat, or a submerged object.
• Weather damage: Storms, lightning, or hail that damage your boat.
• Fire or explosion: Covers accidental fires or explosions on board.
• Theft or vandalism: If your boat is stolen or damaged by vandals.
• Salvage and wreck removal: Helps pay to recover or remove a damaged boat from the water.

What Is Agreed Value?

Agreed value is a type of valuation method used in hull insurance. When you and your insurer agree on a specific value for your boat at the time you buy the policy, that becomes the maximum amount you’ll receive if your boat is a total loss. This is different from actual cash value (ACV), where the payout is based on the boat’s current market value at the time of the claim — which can be much lower, especially if your boat has depreciated over time.

Agreed Value vs Actual Cash Value (ACV)

Agreed Value	Actual Cash Value (ACV)
Set value at the time of policy purchase	Value determined at the time of the claim
Higher payout in case of total loss	Payout may be lower due to depreciation
More expensive premium	Cheaper premium

Why Agreed Value Matters for Boat Owners

Boats, especially yachts, can be expensive and depreciate over time. If you buy a $500,000 boat and set an agreed value of $450,000, you know that if something happens to it, you’ll get $450,000 — not less. With ACV, if your boat is worth $300,000 at the time of the claim, that’s all you get. Agreed value gives you peace of mind, especially for high-value or classic boats.

How Deductibles Work with Agreed Value

Every hull insurance policy includes a deductible (also called an "excess" in some regions). This is the amount you pay out of pocket before your insurance kicks in. If you have agreed value, your deductible is usually a percentage of the agreed value — not the actual cash value.

Example Deductible Calculation

If your boat is insured for $450,000 with a 5% deductible, your deductible is $22,500. That means if your boat is damaged and the repair costs $30,000, you pay $22,500 and your insurer pays the remaining $7,500.

Scenario: Damage Occurs While Outside Navigation Limits

Background

You own a $600,000 yacht insured with agreed value of $550,000 and a 5% deductible. Your policy has navigation limits that restrict you from sailing more than 100 nautical miles from your home port. You take the boat 150 miles out for a fishing trip and hit a submerged rock, causing $100,000 in damage.

What Happens

• Damage amount: $100,000
• Deductible (5% of $550,000): $27,500
• Navigation limit violation: Your policy excludes coverage for damage that occurs outside the allowed area.
• Insurer’s response: You are responsible for the full $100,000 in repairs.

Scenario: Total Loss with Agreed Value

Background

Your $400,000 boat is insured for agreed value of $380,000 with a 10% deductible. A storm causes a total loss — the boat is destroyed and cannot be repaired.

What Happens

• Agreed value: $380,000
• Deductible (10% of $380,000): $38,000
• Insurer’s payout: $380,000 - $38,000 = $342,000
• Your out-of-pocket: $38,000

Scenario: Total Loss with Actual Cash Value

Background

Your $400,000 boat is insured with actual cash value. Due to depreciation, it’s now worth $250,000. A fire destroys the boat.

What Happens

• Actual cash value at time of claim: $250,000
• Deductible (10% of $250,000): $25,000
• Insurer’s payout: $250,000 - $25,000 = $225,000
• Your out-of-pocket: $25,000

How Lay-Up Periods and Warranties Affect Coverage

If you're not using your boat for a period — say, during the winter — you may be able to reduce your premium by placing it in a lay-up period. However, you must follow a lay-up warranty, which typically requires you to:

• Keep the boat in a secure, dry location
• Drain the fuel and water tanks
• Remove the battery or disconnect it
• Close all hatches and doors

Failure to follow the lay-up warranty can void your coverage if a claim occurs during the lay-up period.

What to Know About Named-Storm Deductibles

If your boat is damaged by a named storm — like a hurricane — your deductible may be higher. For example, if your regular deductible is 5%, your named-storm deductible might be 10%. This is a common feature in coastal regions where storms are frequent.

Why You Should Understand Seaworthiness

Your insurance policy may require your boat to be seaworthy — meaning it's in good condition and safe to operate. If your boat is damaged because it wasn't properly maintained or was operated unsafely, your claim could be denied. This is especially important if you're involved in a collision or if your boat sinks due to poor maintenance.

Final Takeaway

Choosing between agreed value and actual cash value is a big decision. If you want to ensure you're fully covered in case of a total loss, agreed value is the safer bet — even though it costs more. Always read your policy carefully, understand your deductibles, and follow any lay-up or navigation rules. Your boat is a big investment — make sure your insurance matches its value.
