Ultima VI: The False Prophet/Map piece in the shipwreck

Homer said: "I think one of the men died in a shipwreck."

Sailors tales
There are several wrecked ships on the coasts of Britannia as well as many tales about them.

Shipwrecks
There are four wrecked ships on the coasts of Britain. From north to south:
 * On an island between Britain and Paws
 * On the Fens of the Dead, just south of Paws (it is the 'Dutchman')
 * On the island off Trinsic
 * On an island between Cape of Heroes and Serpent's Hold (it is the 'Empire')

The map piece can be found on the shipwreck of the Empire.
