Captain Jeffrey R Stone is an Accredited Marine Surveyor with a lifetime commitment in the maritime field. Servicing Rhode Island, Connecticut, Massachusetts and Maine, I provide marine surveys for yachts and commercial vessels in all material types: Wood, cold molded (wood epoxy), fiberglass, composite, aluminum and steel. I have extensive service and experience on vessels from 26' up to 160' and up to 500 GRT
Azimuth Marine Survey provides reliable, professional, and responsive service to our clients.

Non destructive testing is used through out the survey process unless otherwise requested.
Non-destructive test equipment include the following:
  • Thermal Imaging Camera - for use on hull, deck, cored structural components, electrical equipment, and engines - provides a visual image in infrared. The image can identify areas of moisture intrusion and laminate voids in FRP and Carbon layups. Osmotic blisters that have retreated and are not visually detectable can also be seen. Appropriate and inappropriate hot or cool spots in mechanical systems (engine and running gear) and electrical components (switch panels battery chargers, power cords and etc.) can be made visible in infrared. See the representative photos below. The first two sample surveys also contain thermal images.
  • Percussion Sounding Hammer- The first and most universally useful tool for finding soft or separated laminates, and voids in cored and solid FRP and carbon structural components
  • Moisture Meter - helps to define areas of moisture intrusion to cored laminates
  • Infrared Temperature Gun - measures surface temperatures on engine and electrical components
  • Borescope - Flexible tube remote imaging camera for viewing otherwise inaccessible places: wooden vessel frames, under engine pans and mast steps, hull deck joints, and etc.


The mottled dark orange on the image to the left shows the pattern of moisture intrusion to the port quarter of a balsa cored hull with its origin point implied by the dark blue in the upper right. To the right is a sound rudder w/ the rudder post visible as the orange line

The mottled magenta in the image to the left, below, shows moisture intrusion to the deck core on the coach roof just fwd of the dorade box fwd of the mast. The image to the right was taken with the engine under full load.  The near black indicates the raw water pump, the bright white at right is the exhaust manifold, The yellow/white at the bottom left is the oil filter and oil pan.
