The imagery of the drowned port is good and the last line strong.
Stanza 1 has rather a lot of -ing words - Stepping, clacking, grumbling. Complaining, waking..
Clack, grumble, complain, could lose the endings and be stronger for it.
I did find some of your punctuation a bit odd: there are full stops breaking up sentences which I think might flow better with either a comma or no punctuation. (And: does Dunwich have one H or two?)
