He doesn\'t mean that it\'s twelve sectors long; think of it like this:
If a ship is on a side border of a sector it\'s in two sectors at once.
If a ship is on an edge borger of a sector it\'s in four sectors at once.
And if a ship is on a corner border of a sector it\'s in eight sectors at once.
At anything over 1000 meters long, a ship is large enough to potentially sit on two corner borders at once, occupying twelve seperate sectors.
