Instructions
Sail northwest to sector F1 to reach Diamond Steppe Island to recover the Ghost Ship Chart. The Ghost Ship Chart tracks the location of the Ghost Ship on the main Sea Chart. Climb to the island's top with your grappling hook's Hookshot. Drop down the topmost hole and enter the nearby smoking warp pot.
Defeat the Floormaster enemies surrounding the route to the next warp pot. Take a Deku Stick from the nearby hollow pots, and light it with the nearest torch. Burn the top of the rightmost warp pot, and climb in to it. Drop off the end of the ship's corridor after warping there.
Walk to the end of the next ship to find two more warp pots. Burn the left warp pot's top, and jump in to it to reach a chest containing the Ghost Ship Chart. Drop down the nearest platform into a beam of light to return outside.
Press "Up" on the directional pad to view the Ghost Ship Chart. During nighttime, the chart shows the current location of the Ghost Ship; the Ghost Ship's location changes during different phases of the moon. Change the time of day or night with the Wind Waker's Song of Passing to generate a different moon phase if the Ghost Ship doesn't appear. Sail into the Ghost Ship's illuminated entrance to go inside after tracking it down.
