Does a moisture meter read water that is frozen in a stringer or transom as a solid structure or as water ? I'm thinking as a solid structure and wondering what surveyors do in the winter to check for moisture?

It will not pick up frozen water. I had a boat surveyed in the winter once, and was told there was no way to test for moisture, so long is the boat was below 32 degrees.

Great thing to do though weather permitting... huh

unfortunatly in french but video shows, a local surveyor often used by insurance cie, making test in winter at 18 degree farenheight, between 6:00 and say 8:30 in the video, that it does work in winter

I'm sure it work cause I've tried it myself, but i would still trust a little more a test done in warm temperature, at least above freezing temps

Probably if it's any kind of a way out for insurance company to insure or not wanna claim it would be very safe to do -50 below. Lol.. I have no idea but I'd prefer it to be above 40 deg for at least 48 hours or so. Some will allow to be cored for the right price. It can be like cancer.

Here is a good article on surveying a frozen boat.

I am sure it will work with ice anything that conducts eclectic. And if there is carbon fiber moisture meter will not work anymore.

What if it's all dry rot with no moisture. I dug into one like that that literally was like OSB that was water logged and then sat on a basement floor and dried up after a year. Or is a densometer one does all? Never been down that road. Just wondering what's ideal for checking both.

I think at that point you would use the results from the moisture meter and a tapping hammer to know

We ended up drilling holes for proof.
