How Hull Damage Coverage Works

Learn exactly what hull damage coverage protects and why it's essential for boat owners.

Updated July 19, 2026

Hull damage coverage in yacht insurance is the part of your policy that pays to repair or replace your boat if it’s damaged by covered events like collisions, storms, or fire. It’s based on the agreed value you set with your insurer, not the boat’s current market value. If your boat is totaled, you get the full agreed value minus your deductible. This guide explains how it works, including key concepts like deductibles, navigation limits, and agreed value vs actual cash value.

What Hull Damage Coverage Covers

Common Covered Events

Hull damage coverage typically includes:

  • Collision with another boat or object
  • Fire or explosion
  • Storm or lightning damage
  • Grounding or running aground
  • Volcanic eruption or earthquake (in some policies)

What’s Usually Not Covered

Hull damage coverage doesn’t include:

  • Normal wear and tear or mechanical breakdowns
  • Damage from improper maintenance
  • Damage from using the boat in a way not approved by your policy
  • War, terrorism, or nuclear incidents

Agreed Value vs Actual Cash Value

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 the full agreed value minus your deductible. This is popular for older or classic boats, where market value can be hard to determine.

Actual Cash Value (ACV)

Actual cash value is based on the current market value of your boat, minus depreciation. If your boat is totaled, you get the depreciated value minus your deductible. This can mean you receive less than what you paid for the boat, especially if it’s older.

Choosing Between the Two

Agreed value gives you more certainty, especially for high-value or classic boats. ACV is cheaper but can leave you undercompensated if your boat depreciates quickly. Most insurers let you choose which option to use when you buy the policy.

How Deductibles Work

Standard Deductibles

A standard deductible is a fixed amount you pay out of pocket before your insurance kicks in. For example, if your deductible is $5,000 and your boat sustains $20,000 in damage, you pay $5,000 and the insurer pays $15,000.

Named-Storm Deductibles

Named-storm deductibles apply only to damage from hurricanes or tropical storms. These are usually a percentage of your boat’s value. For example, a 5% named-storm deductible on a $500,000 boat means you pay $25,000 for storm-related damage.

Scenario: Damage from a Hurricane

Your boat is worth $500,000 with a 5% named-storm deductible. A hurricane causes $100,000 in damage. You pay the first $25,000 (5% of $500,000), and your insurer pays the remaining $75,000. Total out-of-pocket cost: $25,000.

Navigation Limits and Lay-Up Warranty

Navigation Limits

Navigation limits define the geographic areas where your boat is covered. If your boat is damaged outside these limits, the claim may be denied. For example, if your policy covers only U.S. coastal waters and your boat is damaged in the Caribbean, you may not get coverage.

Lay-Up Warranty

If you’re not using your boat for a long time, you may put it in lay-up. A lay-up warranty requires you to secure the boat in a safe location and notify your insurer. Failing to do so can void coverage if damage occurs during lay-up.

Scenario: Damage Outside Navigation Limits

Your boat is worth $600,000 with a 10% named-storm deductible. You take it to the Bahamas, which is outside your policy’s navigation limits. A storm causes $150,000 in damage. Because the damage occurred outside the covered area, your claim is denied. You pay the full $150,000 out of pocket.

Salvage and Wreck Removal

Salvage

If your boat is damaged and needs to be recovered, your insurer may pay for salvage services. This includes towing, lifting, or recovering the boat from water or land.

Wreck Removal

If your boat is a total loss and needs to be removed from the water, your insurer may cover the cost of wreck removal. This is especially important in areas with strict environmental or navigational rules.

Scenario: Grounding and Salvage

Your boat runs aground and is stuck in shallow water. Salvage costs are $10,000 to free it. Your policy covers salvage up to $15,000. You pay nothing because the cost is within the limit. If the cost were $20,000, you’d pay the extra $5,000 out of pocket.

Total Loss and Constructive Total Loss

Total Loss

A total loss means your boat is so damaged it’s not worth repairing. In this case, you receive the agreed value (or ACV) minus your deductible. For example, a $400,000 boat with a $10,000 deductible is a total loss. You get $390,000 from your insurer.

Constructive Total Loss

A constructive total loss means the cost to repair is more than the boat’s value. For example, a $300,000 boat with $280,000 in damage. You receive the agreed value minus your deductible, and the boat is considered a total loss.

Scenario: Constructive Total Loss

Your boat is worth $350,000 with a $15,000 deductible. It sustains $320,000 in damage. The repair cost is more than the boat’s value, so it’s a constructive total loss. You receive $335,000 from your insurer ($350,000 minus $15,000 deductible).

Key Coverage Limits and Deductibles

Concept Typical Range Example
Standard Deductible $1,000 to $10,000 $5,000
Named-Storm Deductible 1% to 10% of boat value 5% of $500,000 = $25,000
Salvage Coverage $5,000 to $20,000 $10,000
Agreed Value Set at policy start $500,000
Actual Cash Value Varies by depreciation $350,000 for a 10-year-old $500,000 boat

Final Takeaway

Make sure you understand your policy’s agreed value, deductibles, and navigation limits. These details determine how much you’ll pay if your boat is damaged. Review your coverage annually and update your agreed value as needed. A clear, up-to-date policy can save you thousands in a crisis.
