Marine Surveys Local or Nationwide
We work on boats every day, so we know what to look for.
We own and maintain the world's largest database of "Common Problems" by make, model and year, 1932–present. So even before we get to your boat we preview issues that may be of concern with that model. In addition, we thermal-image the hull, decks, hull sides and transom looking for delamination and moisture issues.

Serving the Long Island N.Y. area. Cardona Marine Surveyors can help you determine the condition and value of a boat.
Before we even get to the boat you are looking to buy, we can compile a list of "Common Issues" for that specific make, model, and year boat.
We look for hidden damage on land. Then the boat goes in the water and we sea-trial it with a specific set of tests to uncover possible issues.
All components are checked. We then write a comprehensive survey report with boat condition and current value estimate.
