A boat and a ship are both vessels used for transportation across water. But there are some key differences between them.
Boats are generally smaller than ships and are designed for shorter trips. They are usually used for leisure activities such as fishing, cruising, and watersports. Boats are also powered by outboard motors or oars.
Ships, on the other hand, are larger and are mainly used for commercial and military purposes. They are powered by large engines and are built to travel long distances. Ships have a larger capacity for passengers and cargo, and are often used for transporting goods.
