The Legend of Zelda The Wind Waker 100% #31 Ghost Ship Chart (No Commentary)

The Ghost Ship Chart is a special chart found in The Wind Waker. It can be found on Diamond Steppe Island. After Link climbs to the top of the island using the Hookshot, he can enter a maze of Warp Jars. Finding the correct path through the maze allows him to find a treasure chest containing the chart. As its name suggests, the Ghost Ship Chart allows Link to determine the location of the Ghost Ship. It displays where the Ghost Ship is located at each phase of the moon. The phase in question glows when Link looks at the chart at night, as well as the Ghost Ship symbol in the center. After Link takes the treasure from the Ghost Ship, the chart no longer glows. Additionally, Link cannot enter the Ghost Ship unless he is holding this chart; the ship merely disappears if he encounters it beforehand.[1]

The Ghost Ship Chart is necessary to complete the game so that Link can enter the ship and obtain the Triforce Chart.
