How Much Does a Boat Survey Cost? (What You're Actually Paying For)
The number on the invoice isn't what you're buying — you're buying the list of everything wrong with the boat before it becomes your problem.
The invoice for my last pre-purchase survey came in at $875 — for a guy with a moisture meter, a flashlight, and about five hours on the boat. My first reaction was that it seemed steep for the equipment involved. My second reaction, after reading the fourteen-page report that came with it, was that I'd have paid double. It found a soft spot behind the aft head bulkhead I never would have caught, and a set of through-hulls original to a boat that had changed hands three times without anyone replacing them.
That's the part nobody tells you when you're pricing out a survey. The number on the invoice isn't really what you're buying. You're buying the list of things wrong with a boat before they become your problem instead of the seller's. Whether that's worth $875 depends entirely on what's in the report — and you don't find that out until after you've paid for it.
Here's what a marine survey actually costs in 2026, what changes the price, and what to do with the report once you have it.
The Short Answer
A marine survey costs $20 to $25 per foot of boat length, which works out to $700 to $875 for a 35-foot boat and $1,000 to $1,250 for a 50-footer. Most surveyors have a minimum fee of $400 to $500 regardless of size, so a small boat under 20 feet still costs close to what a 25-footer does. Haul-out, if the boat needs to come out of the water, adds $300 to $600 on top. An engine survey — a separate service, done by a mechanic rather than the marine surveyor — typically runs another $200 to $500 per engine.
Those are pre-purchase survey rates. Insurance surveys and appraisal-only surveys are usually priced the same way, though some insurers negotiate flat rates with specific surveyors for routine renewals.
The Three Types of Survey, and Why the Name Matters
“Survey” gets used loosely, but there are three distinct services, and asking for the wrong one wastes money.
Pre-purchase, or condition-and-valuation survey. The full inspection: hull, deck, structure, systems, safety equipment, and a valuation opinion. This is the one you need before buying a boat, and the one insurers usually accept as proof of condition.
Insurance survey. A lighter version of the same inspection, often done without haul-out, focused on establishing that the boat is insurable and roughly what it's worth. Insurers typically require one for boats over 10 years old or over a certain value, and some will accept a pre-purchase survey done within the last 12 months instead of ordering their own.
Damage or appraisal survey. Done after an incident, or purely to establish current value for a sale, refinance, or estate purposes. No general condition opinion — just a focused answer to a specific question.
If you're buying a boat, ask for a condition-and-valuation survey by name. A surveyor who only does insurance work may not check things a buyer needs to know about, like the standing rigging's age or the state of the below-waterline fittings.
What a Boat Survey Costs, by Size
| Boat Length | Typical Survey Cost | Haul-Out (if needed) | Engine Survey (per engine) |
|---|---|---|---|
| Under 20 ft | $400–500 (minimum fee) | $150–300 | $150–300 |
| 20–30 ft | $500–750 | $200–400 | $200–350 |
| 30–40 ft | $700–1,000 | $300–500 | $250–400 |
| 40–50 ft | $1,000–1,250 | $400–600 | $300–500 |
| Over 50 ft | $1,250–2,000+ | $500–900+ | $400–700+ |
These are North American ranges for a standard fiberglass sail or powerboat. Add roughly 15–25% for steel, aluminum, or wood hulls, which take longer to inspect properly, and for multihulls, which have two or three hulls' worth of through-hulls and structure to check in the same visit.
What Pushes the Price Up
Haul-out. An in-water survey is faster and cheaper, but it can't check the bottom, the running gear, or the through-hulls from outside the hull. For a pre-purchase survey, insist on haul-out. It's the single most common thing sellers try to avoid, and the single most common place expensive problems hide.
The engine. Most marine surveyors explicitly exclude engine internals from their inspection — they'll note the hour meter reading and visual condition, not compression or injector condition. A proper engine survey is a separate booking with a marine mechanic, and it's the item people skip most often to save $300, right before the item that actually fails.
Age and complexity. A 1985 wooden trawler takes longer to survey properly than a 2015 production fiberglass sailboat, and the invoice reflects it. Custom electrical systems, non-standard rigging, and older boats with a longer maintenance history to review all add time.
Location. Surveyors in high-demand markets — the Pacific Northwest and California boating season, the Northeast in spring — charge more and book out further. Travel fees apply if the boat is more than 30–50 miles from the surveyor's base.
Rush timing. Needing a survey inside a tight subject-removal window, common in competitive markets, sometimes carries a rush premium of 10–20%.
What the Surveyor Is Actually Checking
A condition-and-valuation survey covers the hull and deck structure (moisture readings with a meter, soft-spot checks by tapping and pressing), all through-hull fittings and seacocks, standing and running rigging on a sailboat, the electrical system's wiring and panel, plumbing, the fuel system, safety equipment on board, and the steering and control systems. You get a written report with findings sorted by severity — usually something like safety-critical, needs attention, and cosmetic or deferred maintenance.
What you don't get, unless you've booked it separately, is a real opinion on the engine's internal condition. That gap is the one that costs people the most after closing, because a boat can survey beautifully and still need a $6,000 engine rebuild eighteen months later.
Reading the Report and Using It
A survey with findings on it isn't a reason to walk away — it's a negotiating tool and, if you go ahead with the purchase, a punch list. Major structural damage, significant core moisture, or a failed engine survey are reasons to reconsider. A list of aging safety gear, tired hoses, and deferred maintenance is normal on almost every used boat and is exactly what the report exists to surface.
The mistake I see most — and made myself, on an earlier boat — is treating the survey as a one-time gate you pass through and then filing the PDF. Every finding on that report is a task with a rough cost and, often, a real safety implication. A surveyor who flags “fire extinguishers expired 2023” isn't being pedantic. That's a task with a due date, and six months later nobody remembers it was ever written down.
Make the Survey Earn Its Keep
You just paid $700 to $1,250 for someone to tell you exactly what's wrong with your boat. The report is worth the most in the first month, while every finding is fresh, and worth the least a year later when it's a PDF in a folder nobody's opened since closing.

My Boat Brain lets you turn a survey report straight into a tracked to-do list — log each finding as a task or piece of equipment, set a recurring reminder for the ones tied to engine hours or a calendar interval, and keep the original report attached for the day you sell the boat and hand it to the next buyer's surveyor. It's the same $9/month per vessel whether you're tracking one finding or forty. 30-day free trial, no credit card. myboatbrain.com
