Which two framing types are combined in mixed framing?

• A. Longitudinal, transverse
• B. Fore, aft
• C. Port, starboard
• D. Deck, hull

Answer: (A)

Mixed framing uses both longitudinal and transverse framing. Longitudinal framing runs along the length of the hull, carrying bending moments and giving strength along the ship’s axis. Transverse framing runs across the ship, at right angles to the length, helping maintain the vessel’s shape and resist transverse stresses. Combining these two types provides efficient stiffness and weight distribution: the longitudinal members handle bending along the length, while the transverse frames keep the hull plumb and transfer loads into the framing system. The other terms describe directions or parts rather than framing methods, so they don’t fit as framing types.
