Pronunciation: [bˈɑː kˈiːl] (IPA) 
The correct spelling of the nautical term "bar keel" is /bɑr kiːl/. The "bar" refers to the long, flat piece of metal used to balance the ship, while the "keel" is the backbone of the vessel. Together, the bar keel helps the ship maintain stability in rough waters. The pronunciation of the word is important in ensuring clear communication in a seafaring environment.
A bar keel is a prominent feature of a vessel's hull design that helps to stabilize and control the ship's motion in water. It refers to a longitudinal extension or protrusion from the lower portion of the vessel's hull, typically running along the centerline.
The bar keel is usually made of steel or reinforced concrete and is fixed to the ship's main structure. It extends from the bow (front) to the stern (rear) of the ship and is designed to improve the vessel's stability by lowering its center of gravity. This helps reduce the ship's rolling motion, making it more resistant to the effects of waves and ensuring a smoother ride, especially in rough seas.
Furthermore, the bar keel also enhances the vessel's steering capabilities. By acting as a sort of rudder, it aids in maintaining the ship's course and counteracts the forces of lateral drift caused by wind or currents.
In addition to its stability and steering benefits, the bar keel provides structural strength to the ship's hull, adding rigidity and resistance to twisting during maneuvering or when experiencing turbulent waters.
Overall, the bar keel is an essential component of a vessel's design for maintaining stability, controlling motion, improving steering, and ensuring the structural integrity of the ship. Its presence enables safe and efficient navigation, enhancing the overall performance of the vessel at sea.
The term "bar keel" is derived from two words: "bar" and "keel".
The word "bar" originally comes from Old English "bearu" or "bearo", which meant a sandbank or a shallow area in a body of water. Over time, the meaning of "bar" extended to include any obstruction or impediment in a river or harbor, such as a sand or gravel bar.
The word "keel" comes from Middle English "kele" or "kiele", which ultimately originated from Old English "ceol". "Ceol" originally referred to a ship or a vessel, and it later evolved to mean the structural basis or backbone of a ship. The keel is the central longitudinal timber or steel beam that runs along the bottom centerline of a ship, providing stability and strength.
When combined, "bar keel" describes a specific type of ship design.
