A professional marine survey may use thermal imaging and other inspection methods to identify anomalies that deserve closer evaluation before a buyer completes the purchase
If you're buying a used boat in Florida, a marine survey and a sea trial are two of the most important steps in the purchasing process. A marine survey evaluates the vessel's structural integrity, systems, and overall condition, while a sea trial verifies how the boat performs on the water under real operating conditions. Together, they help identify potential issues before closing, giving buyers greater confidence and protecting their investment.
At Jupiter Marine Sales, we've guided buyers through hundreds of successful boat purchases across Florida. One lesson has remained consistent throughout the years: never skip either the survey or the sea trial.
Buying a boat is one of the largest recreational investments many people will ever make. Whether you're purchasing your first center console, upgrading to a larger offshore fishing boat, or investing in a luxury yacht, it's easy to get caught up in the excitement of finding the perfect vessel.
While beautiful gelcoat, low engine hours, and upgraded electronics may be appealing, appearances alone don't tell the whole story.
A professional marine survey combined with a properly conducted sea trial provides valuable insight into a boat's true condition and performance. These steps often uncover issues that cannot be seen while the boat is sitting at the dock and can save buyers thousands of dollars after closing.
A marine survey is an independent inspection performed by a qualified marine surveyor. Think of it as the boating equivalent of a home inspection.
During the inspection, the surveyor typically evaluates:
Depending on the vessel, the surveyor may also recommend additional inspections by certified engine technicians for Yamaha, Mercury, Suzuki, Volvo Penta, Caterpillar, Cummins, or other propulsion systems.
Selecting an experienced, independent marine surveyor is one of the most important decisions you'll make during the buying process.
At Jupiter Marine Sales, we've developed relationships with some of the most respected surveyors in Florida. One of our most trusted recommendations is Coast 2 Coast Marine Surveyors, a licensed and insured marine surveying company with more than 20 years of experience providing pre-purchase surveys, insurance surveys, valuation surveys, and damage inspections throughout South Florida.
They are one of our most trusted surveying partners and have performed more than 300 marine surveys for Jupiter Marine Sales clients alone, consistently delivering thorough, professional reports that help buyers make informed decisions.
As with any surveyor, buyers should choose an independent professional they are comfortable working with and ensure the surveyor has experience with the specific type of vessel being purchased.
A sea trial is your opportunity to evaluate how the boat actually performs on the water. Unlike a dockside inspection, a sea trial allows buyers, brokers, mechanics, and surveyors to observe the vessel under real operating conditions.
During a typical sea trial, you'll evaluate:
Many performance or mechanical issues only become apparent while the vessel is underway, making the sea trial an essential part of the buying process.
A successful sea trial begins before the engines are ever started.
Always review the marine weather forecast, tide conditions, and local navigation information. Buyers should also check the latest U.S. Coast Guard Marine Safety Information Bulletins (MSIBs) for temporary hazards that may affect the planned route. These bulletins can include safety zones, bridge restrictions, dredging operations, shoaling, aids to navigation issues, and other hazards that may not yet appear on your chartplotter.
At Jupiter Marine Sales, we review local marine conditions with our clients before scheduled sea trials whenever practical, helping ensure a safer and more productive on-the-water evaluation.
One of the most common misconceptions is that a successful sea trial eliminates the need for a marine survey.
It doesn't.
A boat can perform exceptionally well during a one-hour sea trial while still having hidden structural or mechanical issues such as:
Likewise, a marine survey cannot fully evaluate how the boat performs under load or how the engines behave at cruising speeds and wide-open throttle.
These two inspections complement one another and provide a far more complete picture of the vessel's overall condition.
Professional surveys often uncover items that are relatively inexpensive to repair but important for buyers to know before closing.
Common findings include:
Many of these items become negotiation points rather than deal breakers.
One of the greatest benefits of a professional survey is that it provides objective information for both buyer and seller.
Depending on the findings, buyers may negotiate:
An experienced yacht broker helps both parties reach a fair agreement while keeping the transaction moving toward a successful closing.
Buying a boat involves much more than simply finding the right listing.
At Jupiter Marine Sales, we help coordinate every step of the transaction, including:
Our goal is to make the entire buying process as smooth, transparent, and enjoyable as possible.

While Florida law does not require a survey for every used boat purchase, many lenders and insurance companies do. Even when it's optional, a professional survey is one of the best ways to protect your investment.
Most surveys take several hours, depending on the size and complexity of the vessel. A detailed written report is typically provided afterward.
No. A survey and sea trial evaluate different aspects of the boat. Together they provide the most complete picture of its condition and performance.
Yes. Survey findings frequently lead to negotiated repairs, credits, or purchase price adjustments before closing.
A marine survey and sea trial are among the smartest investments you can make when purchasing a used boat. Together, they provide a comprehensive understanding of the vessel's condition, performance, and overall value before money changes hands.

Placing a yacht on the internet is easy. Choosing the right advertising strategy is not.
Professional yacht brokers do not select advertising platforms simply because they are popular or because competing brokers use them. They consider the vessel, likely buyer, price range, location, seaso
A boat can be mechanically sound, well equipped, and located in one of the most active boating markets in the country—and still sit unsold for months.
When that happens, sellers often blame interest rates, fuel prices, the economy, the season, or a lack of serious buyers. Those factors can
I recently sat down with Jamin Goecker from Palm Beach County Living for a wide-ranging conversation about moving to Jupiter, boating in South Florida, raising a family in Palm Beach County, and building Jupiter Marine Sales and Florida Yacht Trader.

Preparing a boat properly, taking professional photographs, writing a compelling description, and producing a detailed video walkthrough are all essential parts of selling a vessel.
But none of those things will generate results if buyers never see the listing.
