The keel is a fundamental component of a ship's design and serves primarily as a structural member. It runs along the bottom of the hull and provides lateral stability, preventing the ship from sliding sideways in the water, which is particularly important during rough weather or when the ship is making sharp turns. The keel's structural integrity helps support the weight of the ship and withstands forces from waves and the water pressure as the vessel moves.

While the keel does contribute indirectly to buoyancy by helping to shape the hull and providing a stable base for other components, its primary role is not to provide buoyancy. Instead, it reinforces the overall structure of the vessel. It also plays a part in steering indirectly, as the stability provided allows for better control of the ship when combined with the rudder. However, steering in a ship is more directly associated with the use of a rudder and not the keel itself. Lastly, controlling sails involves the rigging and sail arrangements, which are separate from the keel's purpose.

Understanding the role of the keel is crucial for grasping basic naval architecture and ship operation principles, emphasizing its importance as a structural element within a ship's build.
