Inspection With a Scare
What We Learned About Boat Inspections
With the kids safely with their grandparents, Reiss and I flew out for our long-awaited boat inspection trip, giddy about a few kid-free days and the boat we'd been dreaming about for months. Then I turned my phone on after landing and found a frantic WhatsApp message waiting. An accident, involving our boat. Before we'd even seen it in person.
We couldn't reach the broker. Every unanswered call fed the panic a little more. Had we been scammed? Was this whole thing about to fall apart before it started? By the time a message finally came through, hours later, we'd run through every worst-case scenario twice.
The real story was almost anticlimactic: a neighbouring boat hadn't been properly secured, a storm pushed it into ours, and the damage was cosmetic, a bit of paint and a toerail, covered by insurance on both sides. We went ahead with the inspection. We fell for the boat. And we still walked away with real question marks: some unexplained water in the bilge, and uncertainty about how much life was left in the teak deck and sails.
That water in the bilge turned into one of the biggest jobs we've ever done on this boat, which is exactly why we think inspections deserve a proper, unromantic breakdown. Here's what we've learned about what to actually check, what a survey does and doesn't cover, and what to trust when someone tells you not to worry about something.
What a Boat Inspection Actually Is
There's a difference between a few things people lump together as "the inspection":
- A viewing – walking the boat with a broker, mostly a first impression, not a technical check
- A pre-purchase survey – a paid, independent, qualified marine surveyor going through the boat systematically and producing a written report
- Your own inspection – you, physically checking things yourself, asking questions, and trusting your own eyes and nose over anyone's reassurances
- A sea trial – taking the boat out under power and sail to see how it actually performs, not just how it looks tied to a dock
All four matter. We leaned hard on the survey and the viewing and didn't push hard enough on our own inspection, which is exactly how a bit of water in the bilge slipped past everyone into a boat we'd already agreed to buy.
How Inspections Actually Go in Real Life
Here's the honest version, not the brochure version. You're often jet-lagged, on a tight schedule, and emotionally already halfway to owning the boat before you've stepped aboard. Brokers are generally decent people doing their job, but their job is to sell the boat, not to talk you out of it. Sellers have a story ready for every quirk, and most of those stories are at least partly true, which makes them easy to accept without pushing further.
In our case, the explanation for the water in the bilge was that it came from a corroded boiler. That was plausible. The boiler really was corroded. It just wasn't the actual source, and nobody, including the surveyor, dug deeper before we signed.
That's the real lesson: a reasonable-sounding explanation is not the same as a confirmed one.
What to Actually Pay Attention To
Hull and keel Look for blistering (osmosis), soft spots when you press or tap the hull, staining around the keel-to-hull joint, and any signs of previous repairs that weren't disclosed.
Rigging Ask the age of the standing rigging. Wire rigging has a realistic lifespan (commonly cited around 10-15 years depending on use and climate), and replacing it isn't cheap. Check for rust bleeding at swages, cracked fittings, and chainplates for corrosion where they pass through the deck.
Engine Ask for the hours and the service history, not just a verbal "it runs great." Look for oil in the bilge, corrosion on the block, and ask when the raw water impeller, belts, and mounts were last done. A cold start (engine not run for a few hours beforehand) tells you far more than watching a warm engine start easily.
Electrical system Check for exposed or unsecured wiring near hatches and deck fittings, corrosion at terminals, and whether the panel is labeled and makes sense. If you want the full picture, our guide to 12V/24V/48V/230V boat electrical systems goes into exactly what to check and how these systems should be wired.
Tanks and plumbing Ask when the water tanks were last inspected, what they're made of, and whether there's been any history of water where it shouldn't be. Taste-test any water you find in the bilge, salt versus fresh narrows down the source fast. We wrote a full breakdown of where bilge water actually comes from and how to trace it, learned the hard way, in our Water in the Bilge guide.
Teak decks and sails Both wear out gradually and both are expensive to replace. Ask the age of the sails and when the teak was last re-caulked or replaced, and don't take "still got a few good years" at face value if the boat is heading into a demanding cruising life.
Documentation Title and ownership history, VAT status (a genuinely important one in Europe), any liens or outstanding finance, flag registration, and CE certification if relevant. This paperwork side is unglamorous and it's exactly the kind of thing that gets rushed at the end of an exciting viewing.
What a Survey Does (and Doesn't) Cover
A proper marine survey is worth paying for, but it's not exhaustive by default. Surveyors typically do a visual and moisture-meter check of the hull, check the rig visually, and note obvious issues, but they don't strip the boat down, and they won't necessarily catch something like a slow tank leak that only shows up after the tanks have been full for a while. Our own surveyor's report never mentioned the water we'd already flagged in the bilge.
Ask directly what is and isn't included before the survey happens, and don't assume "surveyed" means "fully verified." It means "professionally inspected within the scope they were hired for."
What to Trust, and What Not to Trust
Trust:
- Your own eyes, nose, and hands, if something smells off, looks off, or feels off, that's real information
- A surveyor you hired independently, not one simply recommended by the seller or broker without you checking their credentials
- Physical evidence like maintenance receipts, service logs, and photos over time
- A proper sea trial under realistic conditions
Be more careful with:
- A confident explanation for something you noticed yourself, confirm it, don't just accept it
- Verbal reassurances with no paperwork behind them ("it's nothing, don't worry about it")
- A survey report that doesn't mention something you can see with your own eyes, that's a gap, not a clean bill of health
- Recommendations for local tradespeople or contractors handed to you on the spot, ask around independently before you hire anyone, a good recommendation from another boat owner in the area is worth far more than the first name you're given
Questions Worth Asking Directly
- Why are you selling the boat?
- Has the boat had any accidents, insurance claims, or groundings?
- Can I see maintenance records and receipts, not just a verbal summary?
- What's the age of the standing rigging, sails, and any tanks?
- Has there ever been water where it shouldn't be, in the bilge, in a locker, anywhere?
What We'd Do Differently
We'd push harder on verifying explanations instead of accepting the plausible one, and we'd treat "the surveyor didn't mention it" as a reason to ask more questions, not fewer. The boat was still the right boat for us. The inspection just could have saved us months of surprise work if we'd trusted our own instincts a little more and other people's reassurances a little less.
FAQ
Is a professional survey enough on its own? It's an important layer, but not the whole picture. A survey is scoped to what the surveyor was hired to check, it won't catch everything, especially issues that only show up under specific conditions like full water tanks or a running engine.
What's a normal thing to see during an inspection versus a red flag? Cosmetic wear, honest signs of use, and disclosed prior repairs are normal on any boat with real history. A red flag is an explanation that doesn't hold up when you ask a follow-up question, or a survey report that's silent on something you can see yourself.
Should I bring someone else along to an inspection? If you can, yes. A second set of eyes, ideally someone mechanically minded or an experienced sailor, catches things you'll miss when you're emotionally invested in the boat already.
What should I do if I find something during my own walk-through that the survey missed? Ask about it directly, in writing if possible, before moving forward. A gap between what you see and what the report says is worth resolving before you sign, not after.
