keel

The keel is a crucial structural component of a ship or sailboat located along the bottom centerline, running lengthwise from front to back. Its primary functions are to provide stability by preventing the vessel from tipping sideways, act as a backbone that maintains the boat’s shape, and help with steering and balance. In sailboats, the keel also interacts with the wind on the sails to generate forward movement. Essentially, it’s a foundational element that ensures the vessel remains balanced, steady, and capable of efficient navigation through water.
