How Often Should You Get a Hull Survey?

How often should you get a hull survey? Most boat and yacht owners should get a full hull survey every 3 to 5 years, and a more basic annual condition check every year. If your boat is older than 10 years, or if you're storing it for long periods, you may need a survey more often. This guide explains why, how, and when you need hull surveys, and how they connect to your insurance coverage.

Why Hull Surveys Matter for Your Insurance

A hull survey is a professional inspection of your boat’s structure and systems. It checks for hidden damage, wear, and safety issues. Insurance companies use these surveys to assess risk and determine coverage terms. If you skip a survey when required, your insurance might not pay out after a claim.

Key Insurance Concepts Related to Hull Surveys

• Agreed Value vs. Actual Cash Value (ACV): Agreed value means your boat is insured for a set amount you agree on with your insurer. ACV means the payout is based on the boat’s current market value, which can be lower. Hull surveys help determine the agreed value.
• Seaworthiness: Your boat must be seaworthy to qualify for coverage. A survey proves it is in good condition and fit to sail.
• Salvage and Wreck Removal: If your boat is damaged beyond repair, the insurance company may take it as salvage. A recent survey helps determine if the damage is a total loss.
• Lay-Up Warranty: If you're not using your boat for a long time, you must follow specific storage rules. A survey can confirm that the lay-up is done correctly and safely.

How Often You Should Get a Hull Survey

As a general rule, you should get a full hull survey every 3 to 5 years. However, the exact frequency depends on your boat’s age, condition, and use. Here’s a breakdown:

• New boats (0–5 years): A survey is usually done at purchase and again in 5 years.
• Mid-age boats (5–10 years): A survey every 3 to 4 years is recommended.
• Older boats (10+ years): A survey every 2 to 3 years is best, especially if the boat is used frequently or stored outdoors.
• Boats in lay-up: A survey is needed before and after lay-up, and sometimes during the lay-up period if the warranty requires it.

When a Survey is Required by Your Insurance Policy

Some insurance policies require a hull survey under specific conditions. For example:

• When you first take out a policy
• After a major repair or refit
• Before a long lay-up period
• If the boat changes ownership
• If the boat is being moved to a new location or used in different waters

Failure to meet these requirements could result in denied claims or reduced coverage. Always check your policy for survey requirements.

How Surveys Affect Your Agreed Value

If you have agreed value insurance, the survey helps set the insured value of your boat. This is the amount your insurer will pay if your boat is totaled. Without a recent survey, the insurer may argue that the agreed value is too high and reduce the payout.

Scenario: Agreed Value and Survey Timing

You own a 10-year-old 45-foot yacht with agreed value insurance of $300,000. You had a survey 4 years ago. Now, you have a collision that totals the boat. The insurer says the boat is now worth $250,000 and offers to pay that instead of the agreed $300,000. You argue that the survey 4 years ago showed the boat was in good condition, and the agreed value should still apply. The insurer may agree to pay the full $300,000 if the survey is still valid and the damage is unrelated to age or neglect.

Surveys and Lay-Up Periods

If you're not using your boat for a long time, you must follow a lay-up warranty to keep your insurance valid. This includes things like draining the engine, covering the boat, and storing it in a secure location. A survey can confirm that the lay-up is done properly and that the boat is in good condition before and after the lay-up period.

Scenario: Lay-Up and Survey Requirements

You own a 30-foot powerboat and plan to lay it up for 12 months. Your insurance requires a survey before and after the lay-up. You get a survey before storage and again when you bring the boat out. During the lay-up, a storm damages the boat. Because you had a survey before storage and followed the lay-up rules, your insurer covers the damage. If you hadn’t had a survey, the claim might be denied on the grounds that the damage was due to poor storage.

Surveys and Seaworthiness

Your boat must be seaworthy to qualify for coverage. A survey proves that the boat is in good condition and fit to sail. If your boat is damaged due to a lack of maintenance or poor condition, the insurer may deny the claim.

Scenario: Seaworthiness and Survey Timing

You own a 15-year-old sailboat and skip a scheduled survey. You go sailing and the engine fails due to a known but unaddressed issue. You claim the damage under your hull & machinery cover. The insurer investigates and finds that the engine failure was due to neglect. Because you didn’t have a recent survey, the insurer denies the claim, arguing that the boat was not seaworthy at the time of the incident.

How to Choose a Surveyor

Not all surveyors are the same. Look for 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 good surveyor will give you a detailed report that your insurer can use to assess risk and coverage.

Cost of a Hull Survey

The cost of a hull survey depends on the size and type of your boat. Here’s a rough guide:

Boat Length	Estimated Survey Cost
Under 25 feet	$300–$600
25–40 feet	$600–$1,200
40–60 feet	$1,200–$2,500
Over 60 feet	$2,500–$5,000+

These are average costs. Some surveyors may charge more for specialized services like underwater inspections or engine testing.

Final Takeaway

Get a full hull survey every 3 to 5 years, and a basic condition check every year. If your boat is older, in lay-up, or used frequently, you may need a survey more often. A survey helps keep your insurance valid, proves your boat is seaworthy, and protects your agreed value. Always check your policy for specific survey requirements and follow them to the letter.
