What is considered the backbone of the ship?

Explanation:
The backbone in ship structure is the keel, the main structural spine that runs along the centerline from bow to stern. It provides longitudinal strength, tying together the frames and other structural members so the hull holds its shape under bending and pounding from waves. It helps keep the ship straight and distributes loads along the length, contributing to stability, sometimes carrying ballast to tune balance. This central, bottom-longitudinal member is what gives the vessel its fundamental support, unlike the hull (the outer shell), the deck (the top surface), or the mast (a vertical spar for the rigging).
