How much does a marine survey cost in Connecticut?

A marine survey in Connecticut generally costs about $30 per foot of boat length. That works out to roughly $660 for a 22-foot boat, $900 for a 30-footer, and $1,200 for a 40-footer. At Helm Marine Survey, that rate is flat — $30 per foot regardless of make, model, or hull type — and there's no deposit and no credit card required to reserve the date. Payment is due only once the survey is finished and the report is in your hands.

That's the headline number. But "how much does it cost" is really three questions wearing one coat: what's the rate, what does the rate buy you, and what can change the total. Here's all three, plainly.

Marine survey cost in Connecticut, by boat length

Because Helm prices by the foot, the math is easy to run before you ever call. Here's what a standard pre-purchase survey runs at $30 per foot:

No surcharge for a sailboat versus a powerboat, no premium for a wood or steel hull, no "complexity" line item. A 38-foot sloop and a 38-foot trawler are surveyed for the same price. We think pricing should be one of the few things about buying a boat that isn't a surprise.

What the price includes

A pre-purchase survey at Helm is a credentialed, top-to-bottom inspection of every accessible system on the vessel, documented in a report your lender and insurer will accept. For the flat per-foot rate, you get:

• Hull and structure — moisture readings on the deck and hull, gelcoat and laminate condition, keel and rudder attachment, bulkheads, and evidence of prior damage or repair.
• Mechanical and propulsion — a visual and operational assessment of the engine, drivetrain, and steering, run and observed in the systems' working state.
• Electrical — wiring condition, panels, batteries, charging, and corrosion, checked against safe-practice standards.
• Rigging and sails (where fitted) — standing and running rigging, fittings, and signs of fatigue.
• Safety gear and systems — bilge pumps, through-hulls, ground tackle, fire and life-safety equipment.
• A 30+ page written Marine Survey Report — photographs of every finding, a plain-language summary, and a fair-market valuation.

The report is delivered within two to three business days of the inspection, which itself takes about four to six hours on-site. The accredited surveyor who inspects your boat is the one who writes and signs the report — no junior handoff, no anonymous template — and you can reach that person directly with questions long after delivery.

What can change the cost

The per-foot rate covers the standard pre-purchase survey. A few situations add to the total, and we quote every one of them up front:

A separate mechanical (engine) survey

Our survey includes a visual and operational look at the engine — we report on what we observe with the systems running. A full internal engine evaluation — oil analysis, compression or borescope testing — is a specialized mechanical survey performed by a marine mechanic. For higher-hour or higher-value engines we'll tell you plainly when one is worth it, and we can coordinate it alongside our inspection.

Sea trial and haul-out

A standard survey covers the vessel in and out of the water as access allows. A sea trial (running the boat under way) and a short-haul or out-of-water inspection can be arranged when the seller or yard makes the boat available. Any yard or lift fees come from the facility, not from us — tell us what you need when you book and we'll coordinate it.

Travel to the boat

Helm travels to the vessel wherever it's slipped or hauled, across all of Connecticut and Long Island Sound — Greenwich to Stonington — plus inland lakes and river systems. For the vast majority of locations there's no travel surcharge; for anything unusually remote, we'll say so before you commit.

How Connecticut pricing compares

Nationally, pre-purchase marine surveys commonly run somewhere between $18 and $30 per foot, and many surveyors quote flat fees with add-on charges layered on for sail rigs, older hulls, or larger vessels. The result is that two buyers with similar boats can pay very different amounts depending on how the surveyor structures fees.

Helm's flat $30-per-foot rate sits at the transparent end of that range: a single, predictable number you can calculate yourself, with the report quality that marine lenders and insurers require. There's no deposit, no card on file, and no payment until the work is done — which is unusual in the trade and, we think, the right way to do it.

Is a marine survey worth it?

For most buyers in Connecticut, a survey isn't really optional. Marine lenders and insurers generally require a recent survey from an accredited surveyor before they'll finance or insure a vessel — so the question is usually which surveyor, not whether.

Beyond the paperwork, the survey is the one moment in a boat purchase when someone independent — working for you, not the seller — looks past the fresh wax and tells you what you're actually buying. On a $900 survey, a single finding that uncovers a soft deck core, a tired engine, or corroded wiring can save many times the cost, or hand you the leverage to renegotiate. The report is yours to use: negotiate, walk away, or proceed with your eyes open.
