China is one of the first countries in the world to make canoes and use canoes and paddles to cross the sea. A canoe is the simplest boat. The log is hollowed out and people sit on it. It evolved from a raft. Although this evolution process is extremely slow, it has taken an important step in the history of ship technology development. Canoes need more advanced production tools and are manufactured according to certain technological processes. Manufacturing technology is much more difficult than raft, and its own technology is much more advanced than raft. It already has a prototype of a ship. In China, there were wooden boats with cabins in Shang Dynasty, and the shipbuilding technology in Han Dynasty was more advanced. Besides paddles, there are anchors and rudders on board.

In the Tang Dynasty, Colliers invented the use of wheels instead of paddles and paddles, and paddles.

Compasses were widely used on ships in the Song Dynasty, with watertight compartments to avoid sinking on rocks. There are also large ships with masts 10 and sails 10.

Around 2900 BC, Egyptians first used sailboats. From then on, until the18th century, sailing has always occupied a dominant position in ocean transportation. At that time, many sailboats were propelled by a mast and a sail. About 500 years ago, many sailboats with 3-4 masts began to appear. This kind of sailing boat has a strong hull and is not afraid of wind and waves. Today, large ships with engines are widely used, and small sailboats are still used for sports competitions, fishing and local trade.
