Hull Insurance vs Total Loss Only

When you're insuring your boat or yacht, you'll often see two main types of hull coverage: **hull insurance** and **total loss only (TLO)**. The difference between them is simple but important. Hull insurance covers both partial and total losses, meaning it pays for repairs if your boat is damaged. Total loss only insurance only pays if your boat is completely destroyed or beyond repair. This guide will help you understand which is right for you, and how other insurance concepts like agreed value, navigation limits, and deductibles affect your coverage.

What is Hull Insurance?

Hull insurance is the most comprehensive type of coverage for your boat. It protects against damage to the physical structure of your boat — the hull — as well as mechanical systems, engines, and onboard equipment. If your boat is damaged in a covered event — like a collision, fire, or storm — hull insurance will pay to repair or replace it, up to the policy limit.

What Hull Insurance Covers

• Physical damage to the hull — like a collision with a dock or another boat.
• Engine and machinery damage — such as a failed engine or electrical system.
• Storm damage — including wind, hail, or lightning strikes.
• Theft or vandalism — if your boat is stolen or damaged intentionally.

What is Total Loss Only (TLO) Insurance?

Total loss only insurance is a more limited form of coverage. It only pays out if your boat is completely destroyed or if the cost to repair it exceeds its value. TLO is often used for older boats or those that are no longer worth the cost of insuring them in full. It's also a good option if you're storing your boat and not using it regularly.

What TLO Insurance Covers

• Complete destruction — such as a fire or sinking that makes the boat unrecoverable.
• Constructive total loss — when repair costs exceed the boat's value.
• Salvage and wreck removal — if your boat is damaged beyond repair, TLO may cover the cost to remove it from the water.

Agreed Value vs. Actual Cash Value

One of the most important decisions when choosing hull or TLO insurance is whether to go with **agreed value** or **actual cash value (ACV)**. This determines how much your insurance company will pay in the event of a total loss.

Agreed Value

Agreed value is a fixed amount you and your insurer agree on when you buy the policy. If your boat is a total loss, you get that full amount — no matter how much it's depreciated. This is great for newer or high-value boats.

Actual Cash Value (ACV)

Actual cash value is based on the current market value of your boat, which takes depreciation into account. If your boat is a total loss, you’ll get less than you paid for it — sometimes significantly less. ACV is often used for older boats or those with lower value.

How Deductibles Work in Hull and TLO Insurance

A deductible is the amount you pay out of pocket before your insurance kicks in. It’s a key part of both hull and TLO insurance, and it can vary depending on the type of damage and the policy terms.

Standard Deductibles

Most policies use a standard deductible, like 5% of the boat's value. For example, if your boat is valued at $200,000 and your deductible is 5%, you’ll pay $10,000 before your insurance covers the rest.

Named-Storm Deductibles

Some policies have a separate deductible for storm-related damage — often higher than the standard deductible. For example, a 10% named-storm deductible on a $200,000 boat would require you to pay $20,000 for hurricane or storm damage, even if your standard deductible is 5%.

Navigation Limits and Lay-Up Warranties

Navigation limits and lay-up warranties are two policy terms that can affect whether your boat is covered when and where you use it.

Navigation Limits

Navigation limits define where your boat can be operated and still be covered. If you take your boat outside these limits — say, from a coastal lake to the open ocean — your insurance may not cover any damage that happens there.

Lay-Up Warranty

If you're not using your boat for a period of time — like during the winter — you may need to put it into a "lay-up" period. During this time, you must follow specific rules, like securing the boat in a dry storage location and not using the engine. If you don't follow the lay-up warranty, your insurance may not cover any damage that occurs during this time.

Scenario: Damage Occurs While Outside Navigation Limits

Boat Details

• Boat value: $500,000
• Navigation limits: Limited to inland lakes and coastal bays
• Policy: Hull insurance with 5% standard deductible

What Happens

You take your boat out to the open ocean for a fishing trip — outside the policy’s navigation limits. While there, you hit a submerged rock and damage the hull. The repair costs $40,000.

Insurance Coverage

• Damage occurred outside navigation limits — no coverage
• You are responsible for the full $40,000 in repairs

Scenario: Total Loss with Agreed Value

Boat Details

• Boat value: $300,000
• Policy: Hull insurance with agreed value
• Deductible: 5% of value = $15,000

What Happens

Your boat is destroyed in a fire. The agreed value of the boat is $300,000. You have a 5% deductible, which is $15,000.

Insurance Coverage

• Insurance pays: $300,000 - $15,000 = $285,000
• You receive the full agreed value minus your deductible

Scenario: Total Loss with Actual Cash Value

Boat Details

• Boat value: $300,000 (original purchase price)
• Current market value: $180,000 (after depreciation)
• Policy: Hull insurance with actual cash value
• Deductible: 5% of current value = $9,000

What Happens

Your boat is destroyed in a storm. The insurance company assesses the actual cash value at $180,000. You have a 5% deductible, which is $9,000.

Insurance Coverage

• Insurance pays: $180,000 - $9,000 = $171,000
• You receive less than the original purchase price due to depreciation

Other Important Concepts to Know

There are several other insurance concepts that can impact your coverage and claims, even if you're only comparing hull and total loss only insurance.

Salvage and Wreck Removal

If your boat is a total loss, your insurance may cover the cost to remove it from the water and dispose of it. This is especially important if your boat sinks or is damaged in a remote location.

General Average

General average is a maritime law concept that allows all shipowners to share the cost of a loss if it was made to save the ship or cargo. For example, if your boat is damaged to save others during a storm, your insurance may cover the cost under a general average claim.

Seaworthiness

Your boat must be seaworthy — in good condition and fit for the waters you're sailing. If an accident happens because your boat wasn't properly maintained, your insurance may deny the claim.

Choosing Between Hull and Total Loss Only

Here’s a quick comparison to help you decide:

Feature	Hull Insurance	Total Loss Only (TLO)
Covers partial damage	Yes	No
Covers total loss	Yes	Yes
Typical use	Active, regularly used boats	Older or stored boats
Cost	Higher	Lower
Best for	Newer or high-value boats	Older or lower-value boats

Final Takeaway

If you're actively using your boat and want full protection for both partial and total losses, go with hull insurance. If your boat is older, not in regular use, or you're looking to save money, total loss only may be the better choice. Always make sure you understand your policy’s navigation limits, deductibles, and valuation method — these can make a big difference when a claim happens.
