Before editing a game file always make a backup copy of that file. Go to the directory of the following file: "character_init" (Mostly it is in the following path: C:Program FilesBethesda SoftworksPirates of the CaribbeanPROGRAMCharactersEnglish). It must be the one in "English" not in "Characters". Open the file, and go to the following line: "ch.Ship.Type = SHIP_LUGGER_ENGLAND;". Replace "LUGGER_ENGLAND"ch.Ship.Type = SHIP_LUGGER_ENGLAND with the following to get new ships.
ch.Ship.Type = SHIP_BLACK_PEARL (the hull cannot be damaged)
ch.Ship.Type = SHIP_FRIGATE_SAT
ch.Ship.Type = SHIP_FEARLESS
ch.Ship.Type = SHIP_FORT
ch.Ship.Type = SHIP_MANOWAR_ENGLAND
ch.Ship.Type = SHIP_BATTLESHIP_ENGLAND
