Pre-Purchase Boat Surveys in Miami
Buying a used boat or yacht can represent a substantial financial investment.
A professional pre-purchase boat survey in Miami provides an independent evaluation of the vessel before the transaction is completed.
Depending on vessel type and accessibility, our surveyors may inspect accessible portions of the:
Hull and structural components
Deck and superstructure
Engines and propulsion systems
Electrical systems
Fuel systems
Steering systems
Plumbing systems
Navigation electronics
Safety equipment
Batteries and charging systems
Generators
Interior systems
Ground tackle
Accessible tanks and fittings
The completed marine survey report documents observable vessel condition, significant findings, recommendations, vessel specifications, photographs, and valuation information when included in the survey scope.
Boat Inspection Before You Buy
A professional boat inspection can help identify conditions that may not be obvious during a normal vessel showing.
Potential findings may involve:
Structural concerns
Moisture-related conditions
Electrical deficiencies
Fuel-system problems
Corrosion
Machinery concerns
Water intrusion
Safety deficiencies
Deferred maintenance
Previous repairs
Damaged equipment
Underwater damage
Systems requiring further evaluation
The survey provides the buyer with independent information to consider before completing the purchase.

Miami has a substantial yacht and luxury-vessel market, making professional yacht surveying an important part of our South Florida operation.
We inspect vessels including:
Motor yachts
Luxury yachts
Sportfishing yachts
Express cruisers
Trawlers
Center consoles
Cabin cruisers
Sailboats
Cruising yachts
Catamarans
Performance boats
Twin-engine vessels
Multi-engine yachts
Survey scope is adjusted based on vessel size, construction, machinery, equipment, and the purpose of the inspection.
Boat Surveys on Biscayne Bay
Biscayne Bay supports a large recreational and commercial boating community with marinas, yacht facilities, private docks, charter vessels, sailing vessels, fishing boats, and commercial marine operations.
The City of Miami's Dinner Key Marina in Coconut Grove has approximately 582 wet slips, making it one of the area's major boating facilities. The City also operates Miamarina at Bayside, which has approximately 130 slips and accommodates vessels up to 150 feet.
Our surveyors can coordinate inspections at accessible marinas, boatyards, yacht facilities, dealerships, private docks, and storage locations throughout Miami and Biscayne Bay.
Haul-Out Boat Inspections
For comprehensive pre-purchase surveys, we generally recommend arranging a haul-out when practical.
A haul-out allows the surveyor to inspect underwater components that cannot be adequately evaluated while the boat remains afloat.
Typical Haul-Out Inspection Areas
Depending on vessel configuration, inspection areas may include:
Hull bottom
Keel
Propellers
Propeller shafts
Struts
Rudders
Pods
Outdrives
Saildrives
Trim tabs
Through-hull fittings
Transducers
Sacrificial anodes
Underwater running gear
Observable grounding or impact damage
The underwater condition of a vessel can materially affect maintenance costs, insurability, performance, and overall value.
Sea Trial Inspections
A sea trial may also be incorporated into a comprehensive pre-purchase survey.
Depending on vessel configuration and survey scope, observations may include:
Engine startup
Engine RPM
Operating temperatures
Oil pressure
Transmission operation
Steering response
Vessel handling
Controls
Gauges and instrumentation
Navigation equipment
Generator operation
Vibration or unusual operating conditions
A sea trial does not replace specialized engine diagnostics but can provide valuable information about vessel operation.

How Much Does a Boat Survey Cost in Miami?
The cost to survey a boat in Miami depends on several factors, including:
Vessel length
Vessel type
Vessel age
Hull construction
Number of engines
Complexity of onboard systems
Exact location
Type of survey
Haul-out requirements
Sea-trial requirements
Additional testing requested
A basic insurance survey generally costs less than a comprehensive pre-purchase survey because a pre-purchase inspection involves a substantially more detailed evaluation of the vessel.
For an accurate quote, provide our office with the vessel's year, make, model, length, engine configuration, exact location, and type of survey needed.
