The poem imagines a young woman who treats the ocean as something far more serious than a daydream. For her it is a real place she has to go to, because only there can she "find herself." The subtitle, "Little mermaid," and the title, "Broken Princess," hint at a fairy-tale figure who starts out damaged or lost, and who looks to the sea for repair.
The second stanza shows what the journey gives her. When she comes back to the city, the sea is still visible on her: sun in her eyes, wind in her hair, salt on her lips. The word "infinite" suggests she has brought back a sense of something vast, not just a souvenir of a trip. The speaker seems to watch her with admiration, almost awe. The mood is quiet, hopeful and a little dreamy, a feeling of renewal after a period of brokenness, with the city serving as a contrast to the open, windy freedom of the water.
