loki9, thanks, but I got it to work by twiddling the url!
Mr. Chef, what year is your boat? I think the 26 was produced till Grampian folded in the late 70's?
boatpoker, so when the water freezes in the core it won't really be visible by looking for bulges in the deck?
I've tapped here and there on the deck and found variations in several areas. It comes and goes depending on how far I am from leaks where the deck hardware is located. Some areas are just fine, others sound dull. I haven't found much that sounds like a drum.
To bad the moisture meter is a bit on the expensive side. I think I might buy one when I go looking for boat #2. Seems like a very usefull tool for older boats.
