Marine Survey Types

Pre-Purchase Survey

This is the most comprehensive inspection of a vessel and is strongly advised when purchasing a new or used vessel. The purpose of the survey is to gather as much information about the condition of the vessel before purchase. The survey will consist of an inspection of the topsides, hull, cabin and interior that are normally accessible. A haul out and inspection of the hull bottom, running gear and rudder(s). An examination of the visible structural components of the vessel is made. The fuel system, steering system, electrical system, sanitation system, electronics and safety equipment are inspected and tested to ascertain their operation. An inspection of rigging and sails when appropriate can also be made. A sea trial is conducted to evaluate the overall performance of the vessel. A review of the vessel documentation, hull numbers, and the history of service records when available. A current market valuation and replacement valuation of the vessel will also be given. 

​

Insurance Survey

This survey is meant to be a general overview of the vessel and its systems for insurance underwriting and financing. This type of survey is intended for use by insurance and finance companies to determine the underwriting decision of a particular vessel. This survey will not approach the level of a pre-purchase survey. The primary focus is to identify the vessel, its equipment, overall condition and general value without testing full system operation. It also seeks to identify hazardous conditions that pose a safety risk to the vessel and its passengers. An assessment of vessel safety equipment as per the U.S.C.G. Federal requirements are stated. 

​

Appraisal Inspection

Is performed to gather information to justify and determine the fair market of the vessel. This survey may be used in refinancing, legal claims, an estate case, or a donation to charity. The focus of this survey is limited to setting a fair market value based on the vessel systems and overall condition. 

​

Damage Inspection

The surveyor can be retained by an insurance company to determine the cause of a loss and determine the extent of loss-related damage and may be asked to recommend repairs, review estimates, and determine the pre-loss value of a vessel. A vessel owner can retain a surveyor for the same purposes, but for the owner’s behalf.

​

Sea Trial

A sea trial is conducted to determine that the engine operates within the manufacturer's specifications. A rudimentary engine inspection is conducted. The engine is observed for wide-open throttle RPMs, as recommended by the engine manufacturer. The condition of the hoses, belts, and fuel lines are observed. Motor mounts are checked and the engine is monitored for any fluid leaks. Exhaust smoke is gauged and engine temperature readings are taken. Were the manifolds and risers changed? We also check the steering, throttle and shift controls, and any other equipment that may be installed on the vessel. If an engine is not performing properly or a problem is observed, a repair recommendation is made, or you will be advised to consult a manufacturer's certified mechanic for further diagnosis. 

​

Osmosis Testing:

Used to determine if excess moisture is present in areas of the hull that may not be visible to the eye. Moisture can be present without delamination occurring and this can pinpoint potential problem areas. This type of testing may be undertaken on a vessel that shows signs of moisture intrusion around fittings, blisters, or soft spots in the transom stringers and bulkheads. However, this test is not an infallible way to test for moist areas. Many variables come into play when using a moisture meter. These include delamination, bottom paint, voids in the lay-up of mat and resin, water in the bilge, and the length of time the boat has been out of the water. The meter may detect moisture that can only be verified by destructive testing of the hull to verify the meter readings. 

​

Oil Analysis (spectrometry)

This is a test of the engine's oil to determine if excess engine wear is occurring This is based on the different types of metal particles found in the oil. It will also test for fuel, engine coolant, and saltwater contamination. To do an analysis of wear metals, one first needs to know how long the engine oil has been in service, and if any makeup oil was added between oil changes. The main benefit of a first-time oil analysis is that it can determine if there is saltwater, antifreeze, or fuel in the oil. This may tell us if a head gasket is blown or an exhaust manifold is leaking. After the samples are obtained, they are then sent out to a laboratory service. It usually takes 7-10 days before obtaining the results, but well worth the wait. 

​

Corrosion Analysis

We can test your boat for proper bonding and appropriate zinc anode protection. We can also check for stray current corrosion. Corrosion is a serious problem, and if left unchecked can deteriorate submerged metal fittings like props, lower units, and thru-hulls in a matter of days.
