The most common reason one hires a marine surveyor is to aid in the process of buying a yacht or small craft. You should never buy a used boat without having a marine surveyor check it out first. Marine vessels are sizable investments. You'll want to be confident that the boat you're considering will satisfy your needs as well as get a professional's opinion of the boat's condition and value.
Well-conducted surveys provide good information on the vessels' condition but these cannot be fully guaranteed. The surveyor reports the condition of the vessel and accessible areas only as it exists at the time of the inspection.
A qualified marine surveyor should be equipped with the knowledge, skills, experience and training necessary to perform a thorough inspection of the vessel from stem to stern, looking for any faults in structural integrity as well as mechanical and electrical components, safety items, cosmetic appearance, etc.
