Ghost Ship Chart

From Zelda Wiki.org

This chart, used in The Wind Waker, allows Link to track the movements of the Ghost Ship. It shows what island the Ghost Ship is at during each phase of the moon. The chart is found on Diamond Steppe Island in the Warp Jar maze. Link requires the Hookshot to enter the maze, then will need to pick the correct jar and avoid or defeat the Floormasters. Once Link has the Ghost Ship Chart, you can enter the Ghost Ship to get a Triforce Chart.

The man who made the map mysteriously died as soon he had finished it.
