Marine Surveys and Boat Insurance in Connecticut: When You Need One and How to Pass

There is no single industry rule on when a survey is required - it varies by carrier, and one insurer wanting one does not mean they all will. Here is what triggers the requirement, what a surveyor looks at, and how to clear the recommendations.
Why This Question Has No Clean Answer
Search for whether you need a marine survey and you will get confident, contradictory answers. That is because there genuinely is no single set of underwriting requirements across the industry. Some carriers want a survey on any boat over a certain age or length. Others - Progressive among them - do not require one at all.
So the honest answer to "do I need a survey?" is: it depends which carrier you end up with, and that is exactly the sort of thing worth knowing before you have committed to a purchase with a closing date.
What Usually Triggers It
The two common triggers are age and size:
- Age. Surveys have long been a standard requirement on older vessels. Where carriers draw the line varies considerably - some at around ten years, others nearer fifteen or twenty.
- Length. Many carriers require a survey on larger boats, with thresholds commonly in the high twenties of feet and up.
Other things that raise the odds: a hull material or construction the carrier sees rarely, a boat with a claims history, a vessel being brought in from out of state, a major refit, or a high declared value relative to what the market says the boat is worth.
What a Surveyor Actually Examines
A marine survey is a detailed inspection covering the boat's exterior, rigging, interior, safety equipment, electronics and mechanical systems. The surveyor documents current condition and seaworthiness, and produces a value estimate.
That value estimate matters more than people expect. It is what an agreed-value policy gets written against, so a survey does not just clear an underwriting hurdle - it sets the number you would be paid on a total loss. Agreed value versus actual cash value is worth understanding before the survey, not after.
Who Is Allowed to Do It
Insurers generally require the survey to be performed by a certified third-party professional. Specifically, the following are usually not accepted:
- A survey you performed yourself
- One done by the broker selling you the boat
- One done by the marina
The reason is straightforward - each of those parties has an interest in the outcome. Look for a surveyor accredited by a recognised body such as SAMS or NAMS, and confirm with your carrier that their accreditation is acceptable before you book, rather than after you have paid.
Types of Survey - Ask for the Right One
- Condition and value survey. The comprehensive one, and what insurers and lenders normally want. Usually requires the boat hauled so the underside of the hull, running gear and through-hulls can be inspected.
- Insurance survey. Effectively a condition and value survey framed for underwriting.
- Pre-purchase survey. The one a buyer commissions, typically the most thorough, and often accepted for insurance if recent.
- Damage survey. Post-incident, to establish cause and extent. Not a substitute for the above.
If you are buying, commission a pre-purchase survey and ask the surveyor to produce it in a form your insurer will accept. Paying twice for overlapping inspections is a common and avoidable waste.
Timing It Around a Connecticut Season
This is where Connecticut owners get caught. A full condition and value survey generally needs the boat out of the water, which means coordinating a haul with the yard. In spring, every yard on the shoreline is launching boats and every surveyor is booked. If you are buying in April and want to be on the water in May, start the survey conversation before you have an accepted offer.
Off-season has an advantage worth knowing: boats are already ashore, so the haul is not an extra step. If you are buying over the winter, the survey is usually easier to arrange than it will be in April.
What Fails, and What Is Just a Recommendation
A survey report typically ends with findings sorted by urgency. The distinction matters:
- Safety and seaworthiness items - through-hulls, fuel systems, wiring, corroded fittings, gas detection, fire extinguishers, structural issues. These generally must be addressed before a carrier will bind, and there is no negotiating around them.
- Recommendations - things the surveyor thinks you should do that are not immediate hazards. Carriers may accept the risk, ask for a timeframe, or ignore them.
Common items that hold up a binding: old or corroded through-hull fittings, fuel line and hose age, wiring that has been extended informally over the years, missing or expired safety equipment, and soft decks or moisture readings suggesting core saturation.
How to Improve the Outcome Before the Surveyor Arrives
- Have the boat clean and accessible - lockers empty, floorboards liftable, engine spaces reachable
- Assemble documentation: registration, prior survey, service records, any repair invoices
- Replace expired safety equipment beforehand. Flares and extinguishers are cheap and turn up as findings every time
- Fix what you already know about. A surveyor will find it, and a report with fewer findings gets through underwriting faster
- Be present if you can. Watching the inspection tells you more about the boat than reading the report will
If Your Carrier Wants a Survey and You Would Rather Not
Because requirements vary between carriers, "this insurer wants a survey" is not the same as "you need a survey." It is worth having the market checked. But be realistic: on an older or larger boat, most of the carriers worth being with will want one, and a recent survey is also what makes an agreed-value policy possible. It is often less an obstacle than a step toward better coverage.
If your boat is old enough that carriers are getting difficult, that is a different problem with different solutions - see how vessel type affects placement and what actually moves your rate.
