Grand Line

The Grand Line is an ocean where much of the story takes place in the anime and manga of One Piece.

The Grand Line is the ocean current that follows an imaginary line that runs east to west across the middle of the world and perpendicular to the Red Line. In effect, it's the equator in the world of One Piece. The Red Line is a vast continent that circles the globe from north to south and functions as a Prime Meridian. These two Lines divide the two oceans of the world into four seas: North Blue, East Blue, West Blue, and South Blue. This stretch of ocean is said to be the most dangerous place in the world, and is sometimes referred to as the Pirates' Graveyard.

[edit] Climate

The weather is unusual on the Grand Line. The currents and weather are extremely unpredictable, as they can change in an instant; this includes ocean currents, winds, storms, blizzards, and other such things. Islands and the surrounding waters are the only areas where weather and currents are stabilized in a predictable manner.

[edit] Navigation

Navigation is considered to be very difficult. Normal compasses do not work on the Grand Line because of the nature of its magnetic fields. The islands located in the Grand Line are highly rich in minerals which disturbs the megnetic fields in the area. In order to navigate the Grand Line a special compass called a Log Pose must be used.

The Log Pose works by locking on to one island's magnetic field and then locking on to another island's magnetic field. The Log Pose can do this for a total of seven different routes that diverge from Reverse Mountain and travel east before merging again to the last island, Raftel which was disovered by Gold Roger. The time for a pose to set depends on the island. One island may take a few hours to set to the next island, while another can take several days. This process can be bypassed by obtaining an Eternal Pose. This version of the Log Pose is permanently set to a specific island and can never change. This makes it easier for a crew to get to a specific island rather than going through a trail of islands.
