 Hatches can be less than water tight.....  not saying yours is.
With the deck floor fuel tank hatch, I sealed it for the fishing season using clear silicone.
This forms a nice barrier against water intrusion, but the silicone is also easy to remove.
Then at the end of last season, I opened it up to air out through the winter since my boat is weather proofed / covered over to keep inside dry.  
The bilge hatch cover I don't bother with, because I open and close it frequently.
