A paddle is a tool used for propelling and steering a boat or kayak through water. It typically consists of a long shaft with a broad, flat blade at one or both ends. Paddles are commonly made from materials like wood, plastic, or fiberglass, and their design can vary based on the type of watercraft and the intended use. In recreational activities, such as canoeing and kayaking, paddles allow users to navigate rivers, lakes, and oceans. The technique of using a paddle involves alternating strokes on either side of the boat to maintain direction and speed. Proper paddling techniques can enhance efficiency and reduce fatigue during water activities.
