Keel design refers to the process of creating the keel, a crucial structural component of a boat or ship. The keel runs along the bottom of the vessel and provides stability, balance, and helps to prevent sideways drift while sailing. Different types of keels, such as fin keels and full keels, are designed based on the intended use of the vessel and the conditions it will encounter. The shape and size of the keel can significantly affect a vessel's performance, including its speed and maneuverability. Designers consider factors like water resistance and weight distribution when developing a keel. Effective keel design is essential for ensuring safety and efficiency in marine navigation.
