— In-game description

The Platform Chart is a special Sea Chart from The Legend of Zelda: The Wind Waker. It is found inside a Submarine near the Flight Control Platform. It shows not only the location of Lookout Towers, but also how many are located in a particular area. This is useful as many of the Lookout Towers contain some sort of treasure, usually Rupees of various amounts.
