Rafts are flat, buoyant structures designed to float on water. They can be made from various materials, including wood, rubber, or plastic, and are often used for recreation, transportation, or rescue operations. Rafts come in different sizes and shapes, depending on their intended use, and can be inflatable or rigid. In outdoor activities, such as white-water rafting, rafts are commonly used to navigate rivers and streams. They provide a stable platform for groups of people, allowing them to enjoy the thrill of moving water. Additionally, life rafts are essential safety equipment on boats, providing a means of survival in emergencies.
