Like most owners with a new-to-us boat that is far from new, I spent the first couple of winters focusing on stuff that just had to be fixed.
This winter I have had the luxury of moving on to things that need doing, but are not immediately obvious. In this case torquing the keel bolts.
Test
Out of interest, before removing the nuts, cleaning them up, lubricating (or not1) and then torquing to specification, I immediately torqued each nut with the wrench set to one third of specification.
