Nautical Term: Half-breadth plan
Definition of Half-breadth plan
truly comprehensive definition: A half-breadth plan is a detailed representation of the longitudinal section of a ship, accounting for half of its total width. This plan provides an accurate depiction of the water lines, which show the various points at which the water reaches on the hull as the ship loads or unloads. Additionally, the half-breadth plan includes the bow and buttock lines, which represent the extreme outer edges of the hull at the bow and stern. Furthermore, the half-breadth plan illustrates the diagonal lines of construction, which provide a clear representation of the way in which the various elements of the hull have been joined together during the construction process. For instance, a shipbuilder might use iron rivets to attach the plates of steel that make up the hull. The diagonal lines of construction on a half-breadth plan would provide a clear and detailed representation of the way in which these various elements have been joined together to form the completed hull of the ship.
