Legendary ships

There are four Legendary ships that are sinkable by the pirate assassin Edward Kenway. These ships drop 20,000R as a reward for sinking them. The ships are located at the four corners of the map, and cannot be boarded or added to Kenway's Fleet.

The four legendary ships include the HMS Prince, La Dama Negra, HMS Fearless and Royal Soverign, and the El Impoluto.
