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:

  • Fuel systems

  • Steering systems

  • Plumbing systems

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.

Yacht Surveys in Miami

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.

Depending on insurer requirements, the survey may document the vessel's hull, structure, machinery, electrical systems, fuel systems, steering, safety equipment, navigation equipment, major installed systems, and estimated fair market value.

If your insurance company provides a specific form or checklist, send it to our office before scheduling.

Engine Oil Sampling & Analysis

Engine and generator oil analysis may be added to a marine survey when appropriate.

Laboratory analysis may help identify indicators involving:

  • Wear metals

  • Fuel dilution

  • Coolant contamination

  • Water contamination

  • Lubricant condition

  • Other abnormal findings

Oil sampling can be particularly useful when evaluating diesel-powered yachts, high-hour engines, generators, and vessels with limited maintenance documentation.

Thermal Imaging & Advanced Inspection Services

Additional inspection tools may be used when appropriate, including:

  • Thermal imaging

  • Digital borescope inspection

  • Moisture testing

  • Engine oil sampling

  • Generator oil sampling

  • Electrical-system observations

  • Additional mechanical inspections

These tools supplement the traditional visual survey and may be used when specific areas warrant further investigation.

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.
