Top Breadth Lines
Top Breadth Lines (TBL) are horizontal lines drawn on the ship's hull at the points where the maximum breadth of the ship is attained. These lines are used as a reference for various calculations and measurements related to the ship's stability, loading capacity, and structural design. TBL is an important parameter for shipbuilders and naval architects as it helps in determining the ship's center of gravity, which is crucial for maintaining the ship's stability. TBL is also used to calculate the ship's displacement, which is the weight of the water displaced by the ship's hull. Overall, Top Breadth Lines play a significant role in ensuring the safety and efficiency of the ship's operations.
