Final answer:
All shipboard spaces are given a frame number to identify their position from centerline at which they are located.
Step-by-step explanation:
In shipbuilding, all shipboard spaces are given a frame number to identify the distance, direction, and position from centerline at which they are located.
The frame number refers to the Longitudinal Frame System used in ship construction. Frames are numbered sequentially from the bow (forward) to the stern (aft) of the ship. The number represents the distance in feet from the centerline of the ship.
For example, if a space is identified with the frame number 50, it means that the space is located 50 feet to the starboard (right) side of the centerline of the ship.
