Boat Insurance Survey Requirements

Carriers do not all want the same thing, and the request that lands in your inbox is usually three lines long and assumes you know the rest. Here is what is actually being asked for, and what I will be checking when I get aboard.

What triggers an insurance survey requirement?

Four situations account for almost all of it: the vessel has reached an age threshold, you are taking out a new policy, you are changing carrier, or the existing survey on file has expired. Storm claims history on a hull can trigger one as well.

The request is not a judgment on you or the boat. It is the underwriter refusing to price something nobody has looked at.

How old does a boat have to be to need a survey?

Age is the most common trigger by a distance. Many carriers want a survey once a hull passes somewhere around twenty to twenty-five years, then repeated every three to five years after that. Some want one sooner on wooden hulls or on vessels with a known problem history.

Thresholds vary by carrier and by vessel type, which is why the only reliable answer is the one in your carrier’s own request. Forward it to me and I will read it rather than guess at it.

Do I need a new survey if I change insurance carriers?

A new carrier has no history with the vessel and generally wants a current condition and valuation survey before binding. Switching carriers to save money is a common reason people discover they need one.

Buying a boat usually means both a pre-purchase survey and an insurance requirement, and in many cases one survey satisfies both. Tell me at the outset that you need it to do double duty and it will be written so it does.

What Underwriters Look For

Condition and value, and then specifically the things that cause claims: electrical faults, fuel system deficiencies, fire risk, through-hull and seacock condition, structural integrity, and the state of safety equipment.

They are also looking for the absence of surprises. A vessel with a clear, documented condition report is easier to underwrite than one with gaps, even where the report contains findings.

What a Compliant Report Contains

Full identification of the vessel including hull identification number, a dated condition assessment covering the areas above, findings separated by urgency, photographs, a stated fair market value, and where the carrier asks for it, a replacement cost figure.

It also has to be written by an independent surveyor with no interest in the vessel. A report from the seller, the broker or the yard doing the repairs is generally not accepted, and neither is an older survey that has simply been redated.

What to Fix Before I Get There

Most of what turns up on an insurance survey isn’t structural and isn’t expensive. It’s safety equipment that’s expired, missing, mounted wrong, or was never there in the first place. Every item below is something I find regularly, and every one of them is something you can deal with in a weekend for less than the cost of the survey.

Work through this list before your survey date. It’s the single best use of your time between the letter arriving and me stepping aboard.

Fire Extinguishers

One of the most common deficiencies, and one of the easiest to fix. Portable disposable fire extinguishers have a service life of 12 years from the date of manufacture, which most owners don’t know. Beyond age, they have to be properly mounted, readily accessible and in serviceable condition. Heavy UV damage, corrosion, a broken seal or a damaged gauge will all be written up.

Check that you have the minimum number required for your boat’s length, and then consider carrying more than that. When you actually need a fire extinguisher you’ll want more than the regulatory floor.

Expired Flares and Visual Distress Signals

Pyrotechnic signals – flares and aerial shells – have a shelf life of only a few years, and expired signals don’t satisfy Coast Guard carriage requirements. If your flare kit has been sitting in a dry box for several seasons, it almost certainly needs replacing.

A practical long-term alternative is an electronic visual distress signal paired with a day signal flag. It costs more up front, but unlike pyrotechnics it doesn’t need periodic replacement, so it’s cheaper over time and it removes a recurring compliance item entirely.

Sound Signaling Device

Every vessel has to carry a sound-producing device – a whistle, an air horn or a compressed air canister. Even with a fixed electric horn at the helm, an independent backup is sound practice. Simple, inexpensive, and easy to overlook until somebody goes looking for it.

Required Placards

Federal regulations require specific placards posted aboard, and the requirements scale with length:

• All motor vessels: a No Discharge of Oil placard.
• 26 feet and over: add a Trash Disposal placard.
• 39 feet 4 inches and over: add a written Waste Management Plan and a copy of the USCG Navigation Rules – the paper publication or the app.

Make sure the ones that apply to your boat are posted somewhere visible.

Personal Flotation Devices

Every vessel needs USCG-approved PFDs in serviceable condition for each person aboard, plus at least one throwable (Type IV) that’s immediately accessible. Inspect each one: faded or deteriorating fabric, broken buckles and expired CO₂ cartridges on inflatables are all deficiencies. And a PFD at the bottom of a locker under the dock lines doesn’t meet the “readily accessible” requirement.

Carbon Monoxide and Smoke Detection

Carbon monoxide is a real and recurring cause of boating fatalities – invisible, odorless and fast. ABYC A-24 covers the installation of carbon monoxide detectors and alarms, and a detector is required to monitor the atmosphere in any habitable space aboard.

Habitable space is the term that does the work there. It means a space enclosed by permanent structure with provision for sleeping, cooking, eating, washing, a head, navigation or steering. So in practice: your cabin, your pilothouse and any enclosed area where people sleep or spend real time. If there is no detector, or the one aboard has aged out, that is a priority before the survey.

“A smoke alarm or a smoke detector shall be installed in every sleeping area that is not open to a weather deck.”

NFPA 302, 13.4.2

Bilge High-Water Alarm

On a boat with an enclosed accommodation compartment, a working bilge alarm is a required safety system, not an upgrade. Rising water in an enclosed space can reach critical systems long before anybody sees it.

ABYC H-22, which covers electric bilge pump systems, requires an audible alarm indicating that bilge water is approaching the maximum bilge water level. That level is the point above which electrical or mechanical systems will be adversely affected, with the boat either static or underway.

So check that yours actually works and that it’s positioned correctly – not just that one exists. A sensor mounted too high gives you almost no useful warning.

LP and Propane Systems

If you have an LP system for cooking or anything else, the tank has to be secured in a dedicated vented locker, there has to be a regulator at the tank, and there has to be a pressure gauge. The system also has to hold pressure with all appliance valves closed.

“After pressurization, the system shall maintain pressure with all appliance valves closed for not less than three minutes, without a drop in pressure.”

ABYC A-1

If yours hasn’t been tested recently, test it before the survey. LP leaks are among the most dangerous failure modes on a boat.

Fixed Fire Suppression

Any boat with an enclosed engine space has to have a way of discharging extinguishing agent directly into that space without opening the primary access hatch. NFPA 302 Chapter 12 gives you two ways to satisfy it: a fixed fire extinguishing or suppression system, or a portable clean agent or CO₂ extinguisher used through a discharge port into the machinery space.

The first option is the better one. A fixed automatic system activates when heat hits a threshold and discharges on its own, whether or not anyone’s aboard. The two types you’ll run into are clean agent – modern, environmentally acceptable, highly effective – and Halon, which is legacy but still on a lot of older boats.

The second option is a portable clean agent extinguisher of the right size used through a dedicated port. The part people miss is that the extinguisher has to have a hose, so the agent can be directed into the space without opening the hatch and feeding the fire a fresh supply of oxygen.

Clean agent systems need annual professional service – NFPA 302 E.6.3.2.1 requires every system to be inspected, serviced and tested for operation by qualified personnel at least annually.

Halon needs it twice a year, and deserves a broader note. Halon is an ozone-depleting substance and the EPA has been working to phase it out of the marine industry. Recharging a discharged Halon system is getting harder and more expensive, and the regulatory pressure keeps building. NFPA 302 E.5.2.1 requires semi-annual inspection, testing and documentation by trained competent personnel.

If your boat has Halon, this is a good time to look at moving to a clean agent system – before that decision gets made for you.

Navigation Lights

Every required navigation light has to work. Walk the boat at dusk before your survey date and check all of them – bow, stern, masthead if it applies, anchor light. Replace burned bulbs, deal with corroded sockets, chase down any wiring problems. It’s one of the simplest things to check in advance and one of the most common findings on a report.

What the Process Is Actually Worth

An insurance survey is about more than satisfying a renewal requirement. It’s a standards-based review of the boat you and your family depend on, in the spaces and systems that rarely get looked at between haul-outs.

A good survey finds the shaft packing gland that’s been weeping slowly for a season. It identifies the fire suppression system that’s been out of service for years. It catches the CO detector with a dead battery in the forward cabin. Those aren’t abstract regulatory failures. They’re the conditions that turn into real emergencies on the water.

So when the letter arrives, take it as an invitation – to prepare, to address what you’ve been deferring, and to put a professional set of eyes on the boat before the season starts. Forward me the carrier’s request and the boat details when you are ready to get on the calendar.
