Hull Damage vs All Risk: What's the Difference?
Learn how these two coverages protect your boat—and what they leave out.
Updated July 18, 2026
**Hull damage insurance** and **all risk insurance** are two common types of coverage for yachts and boats. The key difference is that hull damage insurance only covers specific types of physical damage to your boat’s structure, while all risk insurance covers a much broader range of incidents — including theft, fire, and even mysterious disappearance. This guide will explain the difference clearly, with real examples and numbers, so you can choose the right coverage for your boat.
What is Hull Damage Insurance?
Basic Coverage for Physical Damage
Hull damage insurance, also called hull and machinery coverage, is the most basic form of boat insurance. It covers physical damage to your boat’s hull, engine, and other mechanical parts. This type of coverage is essential for protecting your boat from accidents like collisions, grounding, or fire.
What Hull Damage Insurance Does NOT Cover
Hull damage insurance typically does not cover:
- Theft or vandalism
- Fire caused by electrical faults
- Damage from storms or hurricanes (unless you have a named-storm deductible)
- Loss due to sinking or disappearance
- Damage from using the boat in unauthorized areas (outside navigation limits)
What is All Risk Insurance?
Covers More Than Just Physical Damage
All risk insurance is more comprehensive. It covers not only physical damage but also incidents like theft, fire, and even total loss due to unknown causes. This type of coverage is ideal for boat owners who want full protection, especially if their boat is valuable or frequently used in different conditions.
Key Features of All Risk Coverage
All risk insurance includes:
- Coverage for theft and vandalism
- Fire and explosion
- Collision with another vessel or object
- Grounding or stranding
- Damage from storms or hurricanes (with a named-storm deductible)
- Loss due to sinking or disappearance
Agreed Value vs Actual Cash Value (ACV)
Agreed Value: What You Pay, What You Get
With agreed value coverage, you and your insurer agree on a specific value for your boat upfront. If your boat is damaged beyond repair, you’ll receive the full agreed amount, regardless of the boat’s current market value.
Actual Cash Value (ACV): Depreciation Matters
With actual cash value coverage, the payout is based on the boat’s current market value, which takes into account depreciation. This means you’ll receive less if your boat has aged or lost value over time.
| Agreed Value | Actual Cash Value (ACV) |
|---|---|
| Fixed value set at the start of the policy | Value based on current market and depreciation |
| Higher premiums | Lower premiums |
| Guaranteed payout in case of total loss | Payout may be less than what you paid for the boat |
Named-Storm Deductibles and Navigation Limits
Named-Storm Deductibles: A Special Rule for Hurricanes
Many policies include a named-storm deductible, which is a higher percentage of your boat’s value that you must pay if damage is caused by a hurricane or tropical storm. This deductible is separate from your regular deductible and is designed to reduce claims from large-scale weather events.
Navigation Limits: Where You Can and Can’t Go
Navigation limits define the geographic areas where your boat is allowed to operate. If you damage your boat outside these limits, the claim may be denied. For example, if your policy only covers coastal waters and you run aground in the open ocean, the insurer may not pay for repairs.
Scenario: Damage Occurs While Outside Navigation Limits
What Happens When You Break the Rules
You own a $500,000 yacht with hull damage insurance and a 5% named-storm deductible. You decide to take your boat into international waters, outside the policy’s navigation limits. Unfortunately, you hit a reef and cause $100,000 in damage.
Because the damage occurred outside the navigation limits, your insurer denies the claim. You are responsible for the full $100,000 in repairs. This is a costly mistake — and it could have been avoided by staying within the policy’s boundaries.
Scenario: Theft and Named-Storm Deductible
How Deductibles Work in Real Life
You own a $600,000 yacht with all risk insurance and a 5% named-storm deductible. During a hurricane, your boat is stolen from a marina. The total loss is $600,000.
Because the damage was caused by a named storm, you must pay a 5% deductible: 5% of $600,000 is $30,000. Your insurer pays the remaining $570,000. This is a good outcome — all risk coverage protected you from a total loss, and the deductible was clearly defined in the policy.
Scenario: Agreed Value vs Actual Cash Value in a Total Loss
Which Option Pays More?
You own a 10-year-old $400,000 boat. You have two options:
- Agreed value: You and the insurer agreed on $400,000 at the start of the policy.
- Actual cash value (ACV): The boat is now worth $250,000 due to depreciation.
Your boat is destroyed in a fire. With agreed value coverage, you receive the full $400,000. With ACV coverage, you receive $250,000. The difference is $150,000 — a significant amount if you need to replace the boat.
Other Important Concepts to Know
Lay-Up Periods and Lay-Up Warranty
If you’re not using your boat for a long time, you may be able to put it into a lay-up period, which reduces your insurance costs. However, you must follow the lay-up warranty — for example, keeping the boat in a secure location and not using it during the lay-up period. If you break the warranty, the claim may be denied.
Salvage and Wreck Removal
If your boat is damaged beyond repair, the insurance company may pay for salvage and wreck removal. This includes the cost of recovering the boat and removing it from the water. This is especially important if your boat sinks or is lost at sea.
Takeaway: Choose the Right Coverage for Your Boat
Understanding the difference between hull damage and all risk insurance is essential for protecting your boat. Hull damage insurance is more limited and cheaper, while all risk insurance offers broader protection at a higher cost. Always check your policy’s navigation limits, named-storm deductibles, and agreed value or ACV terms. If you want full protection, especially for a valuable or frequently used boat, all risk insurance is the better choice.
One concrete takeaway: If your boat is worth more than $200,000 and you use it regularly, consider all risk insurance with agreed value coverage. This gives you the best protection in case of theft, fire, or total loss — and ensures you get the full value of your boat if it’s ever damaged beyond repair.
Questions, answered
Frequently Asked Questions
- Which type of coverage is better for me?
- If you want broader protection for more types of incidents, all risk is usually better. But if you're on a budget and only need coverage for specific types of damage, hull damage insurance might be enough.
- Does all risk insurance cover everything?
- Not quite — all risk covers a wide range of incidents, but it still has limits and exclusions, like normal wear and tear or damage from not maintaining your boat properly.
- What if my boat is stolen? Which insurance covers that?
- All risk insurance typically covers theft, while hull damage insurance usually does not unless it's part of a covered event like a break-in during a storm.
