Maritime fantasy combines the wonder of fantasy worldbuilding with the unpredictability of the sea. From cursed ships and hidden islands to haunted coastlines and ancient ocean legends, these stories explore worlds shaped by storms, trade routes, piracy, exploration, and survival. Unlike traditional fantasy kingdoms rooted in castles and forests, maritime fantasy is constantly moving — carried by tides, fog, and dangerous waters where entire civilisations can vanish without warning. This collection of 70 Maritime Fantasy Writing Prompts includes plot hooks, opening lines, title ideas, character concepts, setting inspiration, and visual prompts designed to help writers build immersive sea-based fantasy stories. Whether you are creating pirate adventures, storm-driven epics, magical island kingdoms, or atmospheric coastal tales, these prompts encourage rich worldbuilding, tension, and adventure across oceans filled with mystery.
