A boat is a small to medium-sized vessel used for various purposes on water, including transportation, fishing, recreation, and military operations. Boats come in a wide range of sizes, from small, hand-propelled craft like kayaks and canoes, to larger motorized vessels such as yachts, sailboats, and commercial fishing boats. Boats are typically distinguished from ships by their smaller size, and they are often propelled by oars, sails, or engines. They can be made from various materials, including wood, fiberglass, aluminum, and composite materials, depending on their intended use and environmental conditions. Boats are essential for activities such as fishing, water sports, transportation of goods and people, rescue operations, and military maneuvers. They vary greatly in design and functionality based on their intended purpose, from sleek racing boats to sturdy workboats designed for hauling cargo.
