What is the role of the keel on a sailboat?

• A. To assist in steering only
• B. To provide lateral resistance and reduce sideways drift while sailing
• C. To improve the speed of the boat
• D. To store ballast

Answer: (B)

The function of the keel on a sailboat is primarily to provide lateral resistance, which is essential while sailing. As the sails generate lift, the boat can be pushed laterally by the wind. The keel counteracts this force by creating resistance against the water. This lateral stability prevents the boat from drifting sideways, allowing it to move effectively in the desired forward direction. While some people might associate the keel with other functions such as storing ballast or aiding in steering, these roles are secondary to its primary purpose. The keel's design and placement are specifically engineered to enhance the boat’s ability to sail upwind and maintain a straight course by minimizing unwanted lateral movement.
