What Does BL Stand For?
BL stands for Butt Line
BL, or Butt Line, refers to a critical reference line in naval architecture and ship design. It represents the geometric projection of the ship's form at the stern, indicating the point where the hull shape transitions to the freeboard and ultimately meets the waterline. The Butt Line is essential for ensuring optimal hydrodynamic performance and stability, as it aids in the assessment of various design features, including the alignment of the propeller and the overall aesthetics of the vessel. Understanding the Butt Line is crucial for naval engineers and designers in creating efficient and balanced maritime vessels.
