What is Marine Surveying?

Marine surveying is the practice of inspecting marine equipment, primarily boats and cargo, to determine safety and market value. A marine surveyor may be called in to assess a damaged vessel for insurance purposes, appraise a vessel that is being sold, or even serve as an expert witness in court.

Industry Overview

The marine surveying industry is comprised of independent, local marine surveying businesses and professional organizations, like the International Institute of Marine Surveying (IIMS) and the National Association of Marine Surveyors (NAMS Global). Through these businesses and organizations, marine surveyors provide expert advice regarding the safety and value of marine equipment ranging from private yachts to cargo vessels. They may also act as claims investigators for insurance companies or provide expert testimony in marine-related trials.

There are many types of marine surveying. Three common categories are:

  • Surveyors of small watercraft
  • Machinery and hull surveyors
  • Cargo surveyors
