What are types of Loadline on ships and its details?

  • Deck Line – this is the line shown on top which is 300 mm long and 25 mm thick (infact all lines are of equal thickness of 25mm) and it denotes the level of the freeboard deck.
  • The circular symbol with a line passing through it in the middle is directly below the deck line.
  • Summer Load Line  this is the line marked “S” and is in line with the center of the disc. It denotes the depth to which the ship can be loaded when it is floating in salt water in the summer zone.
  • Fresh Water Load Line – this is the line upto which the ship can be loaded in fresh water in the summer zone. It must be noted that when a ship loaded to “F” in fresh water goes into salt water it automatically comes to the “S” level.
  • W and WNA refer to Winter and Winter North Atlantic lines respectively for loading in winter zone
  • TF and T refer to the tropical fresh water line and tropical fresh water line respectively.
