In this anthology we see a thrilling spread of narratives: sailors are pitched against a nightmare from the depth, invisible to the naked eye; a German U-boat commander is tormented by an impossible transmission via Morse Code; a ship ensnares itself in the kelp of the Sargasso Sea and dooms a crew of mutineers, seemingly out of revenge for her lost captain.

The supernatural is set alongside the grim affairs of sailors scorned in these salt-soaked tales, recovered from obscurity for the 21st century.
