Analysis Methods

In the water survey consists of the vessel structural components, decking, ground tackle, electronics, control mechanisms, engine externals, fuel and water storage, sanitation devices, safety systems, electrical wiring and panels, and the overall appearance and condition. An engine run up is performed for control function and basic engine and transmission operation only. Sea trials are performed as per request and are an additional charge.

On the hard examinations include the in-the-water components and continue to structural component checks below the waterline. This includes rudder system, propellers & shafts, through hull fittings, sacrificial anodes, transducers, and other externally mounted items. The engine run up portion is omitted if the vessel is not launched.

Hulls are sounded and checked for voids, delaminations, osmotic blistering, gel coat and paint condition, previous repairs, and existing damage. Hulls are sighted for moisture intrusion and are checked by approved and recognized moisture meters. We use the GRP 33 moisture meter as well as the Extech i5 Flir Infrared Thermal Imaging camera to analyze fiberglass components. As fiberglass boats get older moisture intrusion as well as delamination issues become more frequent. Components are checked for corrosion. This includes galvanic, chemical, and fluid corrosion, wood electrolysis, and grounding/bonding status.

Engines, generators and other machinery are run for general condition and serviceability only. Fluids are checked and reported. Analysis is available. Further investigation of machinery is also available.

Why Have a Marine Survey Performed?

A thorough professional survey can provide you with important information on a vessels condition as well as ascertain the vessels suitability for its intended use. Buying a boat is as much an emotional transaction as a financial one. Love may be blind but through the experienced eyes of a professional surveyor, you will be provided with an objective opinion of the vessels condition and value. Most banks and insurance underwriters require a survey on used vessels. They want to know the condition and fair market value of the vessel they insure or finance. But more importantly you need to know, how safe is this vessel for my family and guests?

How do I Choose a Marine Surveyor?

Talk with prospective surveyors and ask questions! What standards do they use in their surveys? Do they use American Boat and Yacht Council (ABYC), National Fire Protection Association (NFPA), and United States Coast Guard (USCG) Regulations? What does the survey include, and what type of report will I receive? How long will it take and how much will the survey cost?

What Will Gulf of Maine Boat Surveyors Do for You?

We will complete a work order to ascertain vessel information and when you want the survey performed. We will also ask the specific reason for the survey, i.e., a Condition and Valuation Survey for pre-purchase, bank, or insurance requirements. We will then offer a time schedule of the services you contract for and quote the costs involved. You should note that a thorough inspection will be performed and will not be rushed. You will be fully informed of any findings that may require additional inspections. Sea trials are performed at an additional charge at an hourly rate. Remember, a survey conducted in an objective and unbias manner, can only report what is seen and exists that day and are not guarantees of future performance but can give a degree of confidence when determining the vessels condition and value.
