I was debating whether or not to build this boat with hatches. Because it includes shear clamps, I won't have to reach inside to tape the deck seams. I read on another blog, that in this case, you can install waterproof deck plates for access to the watertight compartments, and skip the hatches. However, I do use hatches, so I compromised by planning a hatch for the forward compartment, and a deck plate to access the rear. I decided on a hatch forward, because a deck plate would be too hard to reach.
