Captain Shadow

There is a myth of a cursed shup that sails the seas aith not course, called the Shadow, it's ghostly white sails and rotted hull ever sailing on. as the myth goes it's only maned by one person who was greedy and tried to steal the heart of the Gynia, the queen of the sea. they say he's cursed to always be dead but alive amd never leave the ocean, his crew always hung from the mast as a reminder of his crime. is this true or just an old sea myth like mermaids and sirens?
