Some sea-worthy vessels have this “hatch” at the vessel’s prow that allows loading/unloading vehicles and heavy cargo. How do they keep this watertight, and how do they keep the draft low enough to get near a coastline/pier while maintaining seaworthiness?

1) rubber in between the metal cover and hatch opening.
If it still doesn’t work, it is covered by plastic sheets.

2) by pumping out ballast and ensuring cargo is loaded according to required draft.
