A kayaker is a person who paddles a small, narrow watercraft known as a kayak. Kayaks are designed for one or more people and can be used in various water conditions, including rivers, lakes, and oceans. The paddler uses a double-bladed paddle to propel the kayak forward and steer it through the water. Kayaking can be both a recreational activity and a competitive sport. There are different types of kayaking, such as whitewater kayaking, which involves navigating fast-moving rivers, and sea kayaking, which is done in open water. Kayakers often wear safety gear, including life jackets and helmets, to ensure their safety while on the water.
