Frame Lines
In shipbuilding, frame lines refer to the imaginary lines that run parallel to the keel and define the shape of the ship's hull. These lines are used as a reference for the placement of the ship's structural frames, which are the ribs that give the hull its strength and shape. Frame lines are typically drawn on the ship's plans and are numbered sequentially from the bow to the stern. They are used by shipbuilders to ensure that the frames are correctly positioned and shaped, and that the hull has the correct curvature and symmetry. Frame lines are an essential part of the shipbuilding process and are used in the construction of all types of ships, from small pleasure craft to large commercial vessels and naval warships.
