What Is a Hull Depreciation Clause?
Learn how hull depreciation affects your yacht insurance payout—and what you can do about it.
Updated September 4, 2026
A hull depreciation clause in boat insurance means that if your boat is damaged and needs to be repaired or replaced, the insurance company will pay based on the boat’s current value—not the price you originally paid. This value is calculated by subtracting depreciation (the loss in value over time) from the original price. So, if your boat is older, the payout will be less than what you might expect. This is different from agreed value coverage, where the payout is set in advance and doesn’t change with age or condition.
What Is a Hull Depreciation Clause?
A hull depreciation clause is part of your boat insurance policy that determines how much the insurance company will pay if your boat is damaged or destroyed. Instead of paying the full cost to repair or replace the boat, the insurer calculates the boat’s current value by subtracting depreciation. This means the older your boat is, the less the insurance company will pay in the event of a total loss.
Why Depreciation Matters for Boat Insurance
Boats, like cars, lose value over time. This is called depreciation. If you buy a new $300,000 yacht, it might be worth only $250,000 after five years. A depreciation clause ensures the insurance company doesn’t pay more than the boat is worth at the time of the claim. This helps keep insurance premiums fair and prevents overpayment for older boats.
How Depreciation Is Calculated
Depreciation is usually calculated using a straight-line method. This means the boat’s value decreases by the same amount each year. For example, if your boat costs $200,000 and has a 10-year lifespan, it depreciates by $20,000 per year. After 5 years, it would be worth $100,000. The insurance company uses this value to determine the payout for a total loss.
Depreciation vs. Agreed Value
What Is Agreed Value?
Agreed value is an alternative to depreciation clauses. With agreed value coverage, you and the insurance company agree on a specific value for your boat at the time you buy the policy. This value doesn’t change over time, even if the boat depreciates. If your boat is totaled, the insurance company pays the agreed value, regardless of how old the boat is.
Depreciation vs. Agreed Value: Which Is Better?
Agreed value is often better for older or high-value boats. It gives you more certainty because you know exactly how much you’ll get if your boat is totaled. Depreciation clauses are more common for newer boats or for owners who want lower premiums. However, with depreciation, you might get less money than you expect if the boat is older or in poor condition.
How Depreciation Affects Your Payout
Let’s say you have a $250,000 boat with a depreciation clause. After 5 years, the boat is worth $180,000. If the boat is totaled, the insurance company will pay $180,000, not $250,000. This is the actual cash value (ACV) of the boat. If you want to replace the boat, you’ll need to cover the difference out of pocket.
Depreciation and Deductibles
What Is a Deductible?
A deductible is the amount you pay out of pocket before your insurance kicks in. For example, if your deductible is $5,000 and your boat is damaged for $15,000, you pay $5,000 and the insurance company pays $10,000.
How Deductibles Work with Depreciation
If your boat is totaled and the ACV is $180,000 with a $5,000 deductible, the insurance company will pay $175,000. You’ll receive $175,000, and you’ll still need to cover the remaining $75,000 to replace the boat. This is why it’s important to understand how depreciation and deductibles work together.
Scenario: Depreciation and a Total Loss
Your Boat: $200,000, 6 Years Old
Your boat originally cost $200,000 and is 6 years old. It has depreciated to $140,000. You have a $5,000 deductible. Your boat is totaled in a storm.
- Insurance company calculates ACV: $140,000
- You subtract your deductible: $140,000 - $5,000 = $135,000
- You receive $135,000 from the insurance company
- You need to cover the remaining $65,000 to replace the boat
Scenario: Depreciation and Partial Damage
Your Boat: $150,000, 4 Years Old
Your boat is 4 years old and has depreciated to $120,000. You have a $3,000 deductible. The boat is damaged in a collision and needs $18,000 in repairs.
- Insurance company calculates ACV: $120,000
- Repair cost is $18,000, which is less than the ACV
- You subtract your deductible: $18,000 - $3,000 = $15,000
- Insurance company pays $15,000 for repairs
- You pay $3,000 out of pocket
Depreciation and Named-Storm Deductibles
What Is a Named-Storm Deductible?
A named-storm deductible is a higher deductible that applies when damage is caused by a named storm, like a hurricane. It’s usually a percentage of the boat’s value, not a fixed amount.
How Named-Storm Deductibles Work with Depreciation
If your boat is damaged by a named storm, the deductible is calculated as a percentage of the ACV. For example, if your boat is worth $180,000 and you have a 5% named-storm deductible, you pay $9,000 before the insurance company covers the rest.
Scenario: Named-Storm Deductible and Depreciation
Your Boat: $250,000, 5 Years Old
Your boat is 5 years old and has depreciated to $180,000. You have a 5% named-storm deductible. Your boat is damaged in a hurricane and needs $120,000 in repairs.
- Insurance company calculates ACV: $180,000
- Named-storm deductible is 5% of $180,000 = $9,000
- Insurance company pays $120,000 - $9,000 = $111,000
- You pay $9,000 out of pocket
Depreciation and Salvage Value
What Is Salvage Value?
Salvage value is the amount the insurance company pays if the boat is damaged but not totaled. It’s based on the ACV and the cost to repair the boat. If the repair cost is less than the ACV, the insurance company will pay the repair cost minus your deductible.
How Salvage Value Works with Depreciation
If your boat is damaged but not totaled, the insurance company will calculate the ACV and subtract your deductible. If the repair cost is less than the ACV, you’ll get the repair cost minus your deductible. If the repair cost is more than the ACV, the boat is considered a total loss, and the insurance company will pay the ACV minus your deductible.
Depreciation and Total Loss
What Is a Total Loss?
A total loss is when the cost to repair your boat is more than its ACV. In this case, the insurance company will pay the ACV minus your deductible, and you’ll need to cover the difference to replace the boat.
How Depreciation Affects Total Loss
If your boat is totaled and the ACV is $180,000 with a $5,000 deductible, the insurance company will pay $175,000. You’ll receive $175,000, and you’ll still need to cover the remaining $75,000 to replace the boat. This is why it’s important to understand how depreciation and total loss work together.
Depreciation and Wreck Removal
What Is Wreck Removal?
Wreck removal is the cost of removing a damaged boat from the water. This is usually covered by your insurance policy, but the amount covered may depend on the ACV of the boat.
How Wreck Removal Works with Depreciation
If your boat is damaged and needs to be removed from the water, the insurance company will cover the cost of removal up to the ACV of the boat. If the removal cost is more than the ACV, you may need to cover the difference.
Depreciation and Navigation Limits
What Are Navigation Limits?
Navigation limits are the areas where your boat is allowed to operate. If your boat is damaged outside of these limits, the insurance company may not cover the damage.
How Navigation Limits Work with Depreciation
If your boat is damaged outside of your navigation limits, the insurance company may not pay for the repairs or replacement. This is true regardless of the ACV of the boat. It’s important to understand your navigation limits and stick to them to avoid being denied coverage.
Depreciation and Lay-Up Warranty
What Is a Lay-Up Warranty?
A lay-up warranty is a requirement in your insurance policy that you must follow if you’re not using your boat for a period of time. This usually includes storing the boat in a dry, secure location and not operating it during the lay-up period.
How Lay-Up Warranty Works with Depreciation
If you don’t follow the lay-up warranty and your boat is damaged, the insurance company may not cover the damage. This is true regardless of the ACV of the boat. It’s important to understand your lay-up warranty and follow it to avoid being denied coverage.
Depreciation and Crew Liability
What Is Crew Liability?
Crew liability is coverage for injuries to crew members on your boat. This is usually included in your insurance policy, but the amount covered may depend on the ACV of the boat.

Depreciation and General Average
What Is General Average?
General average is a legal principle that allows shipowners to share the cost of a loss if it was necessary to save the ship and its cargo. This is usually included in your insurance policy, but the amount covered may depend on the ACV of the boat.
How General Average Works with Depreciation
