Haliai
Quite simply, sea nymphs. They show up under this name in a random play by Sophocles and in Callimachus’ Hymn to Artemis (read it!), but doesn’t seem to be as commonly used as the more general “nymph” or the more specific “Nereid” or “Oceanid”. Haliai comes from the word for “sea” and also means “salt”
Link to more about different types of nymphs and individuals. Even more about haliai here.

Well, aren’t YOU the lucky one. From the Nymph site, I learned that Amphitrite (Mrs. Poseidon to you) and her sister nymph Thetis (mother of Achilles) both bore the surname Halosydne, which means “sea-born”, which I think might be a great name for a boat.
