Before You Buy: The Subtle Signals Every Marine Surveyor Learns To Hear
Buying a boat is emotional. Brokers know it, owners know it, and buyers feel it the moment they step aboard. As a marine surveyor, I’m there to slow everything down—to peel back the excitement just long enough to make sure the vessel is being represented fairly, honestly, and without missing pieces. What continues to surprise me isn’t always what’s said during a survey… It’s often what isn’t.
Brokers and owners usually aren’t trying to mislead anyone, but they’re not surveyors either. Their focus is the sale; mine is the vessel’s condition. And over time, I’ve learned that small comments, passing remarks, or oddly quiet moments can reveal more about a boat’s true story than any glossy listing ever will.
As I continue surveying vessels, more of these subtle, real-world scenarios surface — and each one carries a lesson that can help prospective buyers make better decisions. To keep these examples organized, easy to find, and continually updated, I’ve dedicated an entire section of my website to them.
“The Hidden Damage Beneath the Screw: Why Deck Fasteners Deserve More Respect”
Every season, I find it—the innocent little screw that opened the floodgates. A cleat, a rod holder, or a deck fitting installed with good intentions but no understanding of what lies beneath. Most yacht decks aren’t solid fiberglass; they’re sandwiches of fiberglass skins and a lightweight core that gives stiffness without weight. Drive a screw straight into that core and you’ve just created a hidden pathway for water, rot, and structural failure. What looks secure today can quietly destroy a boat from the inside out.
“Probably Just The Bulb”
One of the most common statements I hear during pre-offer conversations is, “I’m sure it’s just a bulb.” A light is out on the masthead, the steaming light doesn’t come on, the spreader lights are dark—and the seller assumes a quick, inexpensive fix. But on a 25–30-year-old sailboat, a non-functioning light aloft is often the first clue of a much deeper issue.
In one recent case, the buyer was told exactly this. After the sale, their rigger went up the mast to “pop in a new bulb” only to discover that the wiring inside the mast was so aged that the copper conductors literally crumbled on contact. The failure wasn’t the bulb—it was the entire wiring run, from masthead to exit, which now required a full replacement. A fix that costs a few dollars quickly became a major job.
“That Tank Hasn’t Been Used In A While”
Buying a boat is emotional. Brokers know it, owners know it, and buyers feel it the moment they step aboard. As a marine surveyor, I’m there to slow everything down—to peel back the excitement just long enough to make sure the vessel is being represented fairly, honestly, and without missing pieces. What continues to surprise me isn’t always what’s said during a survey… It’s often what isn’t.
“The Leak They Tried to Ignore”
When the owner of a brand-new Parker boat discovered water collecting inside his hull, he did what any responsible boater would do — he called the dealer. What followed, however, wasn’t reassurance or resolution, but a pattern of avoidance. The dealership claimed to have found and fixed the source, yet weeks later, the problem persisted. Instead of standing behind their product, management deflected, leaving the owner to navigate the issue alone. By the time I was brought in to investigate, what appeared to be a simple warranty concern had become a deeper story of neglect — one that revealed how easily a small leak can expose a much larger failure in accountability.
