Marine Experience

Few marine surveyors are able to provide the experience which Associated Marine Surveyors have acquired, 4 years as Coast Guard Engineer, 10 years experience as a Diesel Mechanic, many years licensed engineer on Research, Offshore Supply Vessels, Tugboats and mega-yachts, world-wide maritime travel, refits in large shipyards, etc..

As an independent surveying firm, Associated Marine Surveyors is hired to represent you, and report all findings in a clear, professional and timely manner and provide you with valid, objective and unbiased conclusions. This may not be the case with some surveyors, yacht brokers, sales people, shipyard personnel and repair technicians. Often, they will have a financial interest in a survey and hesitant to reveal any unfavorable facts about a vessel. Since we operate as an ‘independent’ party, we can report on a vessel without fear of a monetary loss or retribution.

A credible independent marine surveyor may be your only advocate and we believe that being your best advocate is our only business.
