Offshore (1979) is a novel by Penelope Fitzgerald. It won the Booker Prize for that year. It recalls her time spent on boats in Battersea by the Thames. The novel centralizes around the idea of liminality, expanding upon it to include the notion: 'liminal people,' people who do not belong to the land or the sea, but somewhere in-between. The epigraph, "che mena il vento, e che batte la pioggia, e che s'incontran con si aspre lingue" (whom the wind drives, or whom the rain beats, or those who clash with such bitter tongues) comes from Canto XI of Dante's Inferno.
