Re: Thermal imaging cameras for checking decks and hulls for moisture

Bene,

When we had the survey done on Por Fin, the surveyor used a thermal camera to scan the hull and rudder while the boat was in the slings. Everything checked out A-OK.

Fast forward six months. When I stripped off all the bottom paint, I found (much to my surprise) many, many blisters -- some of which yielded a pretty significant amount of juice. Once it warmed up, the rudder also began to weep a surprising amount of fluid.

Based on my experience, I'd stay away from the thermal camera. About the only useful thing the surveyor found with the camera was a loose screw on one of the breakers on the panel (loose contact which was generating heat.)

YMMV.
