[0002] Ships are a general term for all kinds of vessels. They are means of transportation capable of navigating or anchoring on waterways for transport or operations. Depending on the specific requirements of their use, ships possess different technical specifications, equipment, and structural forms. Ships are a type of man-made transportation primarily operating in geographical waterways. Furthermore, civilian ships are generally called boats, military ships are called warships, and small boats are called vessels or dinghies; collectively, they are referred to as ships or dinghies. Internally, they mainly include interior space, supporting structures, and drainage structures, and possess a propulsion system that utilizes external or internal energy sources. Their external shape is generally a streamlined envelope that helps overcome fluid resistance. Materials are constantly being updated with technological advancements; early materials included natural materials such as wood, bamboo, and hemp, while modern materials primarily include steel, aluminum, fiberglass, acrylic, and various composite materials.
