If the topic is women and the sea, you should certainly include the various "Silkie" songs about mysterious beings who are women on the land and seals in the sea. This is a rich body of lore and there could hardly be a closer relationship between the women and the sea.

On a lighter note, you might consider the Eddystone Light:

Oh my father was the keeper of the Eddystone Light And he married a mermaid one fine night Out of this union there came three A cod and a mackerel and the third was me! Singing yo ho ho, the wind blows free Ah for the life on the rollong sea!
