Do you have a molded fiberglass liner as an overhead? If so, the hatch may have been mounted prior to the deck being attached to the hull, in which case the heads of the fasteners will be between the liner and the deck. I have a number of things fastened that way on my Columbia.
There have to be fasteners holding the hatch assembly to the deck, it's just a matter of finding them. Does it look like any holes have been filled in the area under the trim you removed?
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
