Linebeck, or Linebeck Senior as he is refered to in Spirit Tracks, is a character featured in the game Phantom Hourglass.
He is the captain of the steamboat, the S.S. Linebeck, which Link uses to travel the Great Sea for the full course of the game. Linebeck travels the world seeking treasure, which seems to be his driving force in everything he does, including accompanying Link. People on the islands he visited seem to have a respect or admiration for him, calling him brave and wishing to travel the seas like him. However, Link and Ciela, while journeying, see a different side of him, different from the persona he puts up as a brave adventurer (at one point he claims to go through two dungeons a day before breakfast, though nobody seems to believe him). Instead Linebeck shows himself to be for the most part a coward, running away from trouble and staying with his boat instead of going into the dungeons with Link.
