What Underwriters Want in Survey Reports

Learn exactly what insurers look for in boat surveys to help you get approved and save on premiums.

Updated July 24, 2026

Underwriters want survey reports that are clear, honest, and detailed. They need to know the boat’s condition, its history, and any risks it might carry. A good report helps them decide how much to charge for coverage and what risks to accept. This guide explains exactly what underwriters look for in survey reports and how to meet their expectations.

What Underwriters Want in Survey Reports

Clarity and Specificity

Underwriters don’t want vague descriptions like “the hull looks okay.” They want precise details. For example, instead of saying “the engine runs fine,” a report should state, “the main engine starts on the first try, idles smoothly, and reaches 3,000 RPM without knocking.” This level of detail helps underwriters assess the boat’s condition accurately.

Condition of Key Systems

Underwriters pay close attention to the condition of the hull, engine, electrical system, and safety equipment. A survey report should include:

  • Age and condition of the hull (e.g., no cracks, no soft spots, no blistering)
  • Engine hours and performance (e.g., 1,200 hours on the main engine, no smoke or unusual noise)
  • Electrical system (e.g., no frayed wires, all circuits labeled)
  • Safety gear (e.g., 10 life jackets, 2 fire extinguishers, working bilge pump)

History of Repairs and Modifications

Any major repairs or modifications should be clearly documented. For example, if the boat had a new engine installed in 2022, the report should note the make, model, and hours on the engine. If the owner added a new radar system, the report should describe the brand and installation date. This helps underwriters understand the boat’s history and potential risks.

How Navigation Limits Affect Your Coverage

What Are Navigation Limits?

Navigation limits define where your boat is allowed to operate. These limits are based on the boat’s size, construction, and equipment. For example, a 40-foot monohull might be limited to coastal waters within 100 miles of shore.

Why Navigation Limits Matter

If your boat is damaged while sailing outside its navigation limits, the insurance company may deny the claim. Underwriters want to know if the boat is being used as intended. A survey report should confirm the boat is suitable for its intended use and that the owner understands the limits.

Scenario: Damage Outside Navigation Limits

A $500,000 Yacht with a 5% Named-Storm Deductible

Your 40-foot monohull is insured for $500,000 with a 5% named-storm deductible. You sail it into a hurricane zone, which is outside your navigation limits. The boat is damaged in a storm and needs $100,000 in repairs.

  • Named-storm deductible: 5% of $500,000 = $25,000
  • Damage is outside navigation limits = claim denied
  • You pay the full $100,000 out of pocket

Agreed Value vs. Actual Cash Value

What’s the Difference?

Agreed value is the amount you and the insurance company agree your boat is worth. Actual cash value (ACV) is what the boat is worth at the time of a loss, based on depreciation.

Why It Matters for Claims

With agreed value, you get the full amount you paid for coverage, regardless of the boat’s current value. With ACV, you only get the depreciated value. Underwriters want to know which type of coverage you have and the agreed value if applicable.

Scenario: Agreed Value vs. ACV

A $300,000 Yacht with 5 Years of Depreciation

Your 5-year-old boat is insured for $300,000. You have two options:

Coverage Type Claim Value What You Receive
Agreed Value $300,000 $300,000
Actual Cash Value $300,000 $225,000 (after 25% depreciation)

Seaworthiness and Total Loss

What Is Seaworthiness?

Seaworthiness means your boat is fit to sail. Underwriters want to know if the boat is properly maintained and equipped. A survey report should confirm the boat is seaworthy and ready for its intended use.

What Is a Total Loss?

A total loss happens when the cost to repair the boat is more than its value. For example, if your boat is worth $200,000 and the repairs would cost $210,000, the insurance company will declare it a total loss and pay you the agreed value.

Scenario: Total Loss After a Collision

A $250,000 Yacht with $260,000 in Repair Costs

Your boat collides with a dock and needs $260,000 in repairs. The boat is insured for $250,000.

  • Repair cost > agreed value = total loss
  • Insurance company pays $250,000
  • You keep the wreck or let the company remove it

Salvage and Wreck Removal

What Happens After a Total Loss?

If your boat is declared a total loss, the insurance company may take ownership of the wreck. They might sell it for parts or have it scrapped. You may be entitled to a portion of the salvage value, depending on your policy.

Why Underwriters Care

Underwriters want to know if the boat is a total loss and what the salvage value might be. This affects how much they pay and whether they take ownership. A survey report should include the boat’s condition and any visible damage that could lead to a total loss.

How to Meet Underwriter Expectations

Be Honest and Detailed

Underwriters can tell when a report is vague or misleading. Be specific about the boat’s condition, history, and any issues. If there’s a problem, don’t hide it. A good surveyor will note it and explain it clearly.

Use a Qualified Surveyor

Choose a surveyor who is certified by a reputable organization like the National Association of Marine Surveyors (NAMS) or the Society of Accredited Marine Surveyors (SAMS). A qualified surveyor knows what underwriters want and how to present the information clearly.

Keep Records Updated

Underwriters want to see that you maintain your boat. Keep records of all repairs, maintenance, and upgrades. A well-maintained boat is less risky and easier to insure.

Know Your Policy Limits

Understand your navigation limits, deductible, and coverage type. A survey report should reflect these limits and confirm the boat is being used as intended. If you’re unsure, ask your insurance agent to explain the terms in plain language.

Final Takeaway

Underwriters want survey reports that are clear, honest, and detailed. They need to know the boat’s condition, its history, and any risks it might carry. A good surveyor will help you meet these expectations and make it easier to get the coverage you need. Always use a qualified surveyor, keep your records up to date, and understand your policy limits. This will help you avoid surprises and get the best coverage for your boat.
