Boats are an important means of water transportation. The earliest boats appeared in the Stone Age - canoes (a log hollowed out in the middle). Then, boats with oars and sails appeared. Later came ships powered by steam or diesel engines. Today, people use solar energy and jet engines as power for ships, which can sail at astonishing speeds. The top speed can reach more than 500 kilometers per hour.
China is one of the first countries in the world to manufacture canoes, and uses canoes and oars to cross the sea. A canoe is the simplest boat in which a log is hollowed out and people sit on it. It evolved from a raft. Although this evolutionary process is extremely slow, it has taken an important step in the history of ship technology development. Canoes require more advanced production tools and are manufactured according to a certain process. The manufacturing technology is much more difficult than that of rafts, and its own technology is much more advanced than rafts. It already has the prototype of a boat.
In China, wooden plank ships with cabins had been built in the Shang Dynasty. The shipbuilding technology in the Han Dynasty was even more advanced. In addition to oars, the ships also had anchors and rudders.
In the Tang Dynasty, Li Gao invented the use of wheels instead of oars and oars to row vehicles and oars to row vehicles and boats.
In the Song Dynasty, ships commonly used compasses (compasses) and had watertight compartments to avoid hitting rocks and sinking. At the same time, large ships with 10 masts and 10 sails also appeared. In the 15th century, Chinese sailing ships had become the largest, strongest, and most seaworthy ships in the world. The advancement of ancient Chinese navigation and shipbuilding technology has led the world.
Steam ships appeared in Europe in the 18th century. At the beginning of the 19th century, iron ships appeared again in Europe. In the middle of the 19th century, ships began to develop towards larger size and modernization.

Sailboats
Around 2900 BC, the Egyptians were the first to use sailboats. From then on, sailing ships dominated marine transportation until the 18th century. At that time, many sailing ships relied on one mast and one sail. About 500 years ago, multi-masted sailing ships began to appear. These sailing ships had strong hulls and were not afraid of wind and waves. Today large ships with engines are in widespread use, and smaller sailing ships are still used for sporting events, fishing and local trade.
Freighter
The ship that transports goods is called a freighter. Cargo ships have plied the oceans for thousands of years, allowing people to trade between different parts of the world. Today, a vast number of different types of cargo vessels ply the seas, from large tankers to small tugboats, from car ferries to purpose-built ships designed to search for damaged vessels. Freighters rarely have superstructure (the part above the main deck). The ship has a pilot bridge with a chimney. There are engine and accommodation areas under the bridge. The rest of the boat can accommodate as much cargo as possible.
Hovercraft
Hovercraft has an inflatable air cushion that allows the hull to float out of the water and sail. Because the resistance of the water is reduced, it sails very fast. Hovercrafts do not just float on water, but are supported by air cushions and can move over water, swamps or land. Hovercraft have huge fans to create a cushion of air. This cushion of air is enclosed around the hull by a ring of rubber called an "apron."
Iron boat
The iron boat is a unique ship in the Yangtze River area of ??China. It is unique to China. It is covered with iron on the outside and wood on the inside. It was often used during the Three Kingdoms period and has continued to do so. For more than 1,000 years
Inflatable boats
The first modern inflatable boat was used in the French Navy. ZODIAC's development model triggered the rapid development of the civilian and military inflatable boat industries. Correspondingly, Pierre Debroutelle designed the first U-shaped inflatable boat in 1937, and he applied for a patent for this design on August 10, 1943. This is also the most direct version of the sports and recreational inflatable boat to this day!
Since then many new manufacturers, new models and new designs have been introduced to the market. Inflatable boats are no longer just small rubber boats carried on the back of a large yacht! It can reach 45 feet long or more! "Rigid" fiberglass hulls and aluminum hulls are gradually replacing the original inflatable bottom! Luxurious and beautiful decorative parts and even cabins have also appeared on rubber boats.
Corresponding to its name, today, inflatable boats often only mean that the pontoons of the boat are inflated, and the bottom of the boat may be made of fiberglass or aluminum. However, in any case, inflatable boats have always existed and become more and more popular. It is becoming more and more popular among people!
There are many kinds and models of rubber boats. There are high-speed boats that specialize in pursuing speed, there are completely manual kayaks, there are rafting boats that can experience the fun of rapids, and there are simple-looking working rafts that are used in offshore waters. Fishing boats for fishing etc.
Widely used in water recreation, entertainment, fishing, fishing and other water operations.
Fishing boats
At present, the material used to make inflatable boat pumps in China is generally PVC material.
Performance and advantages of inflatable products: 1. All are made of imported special airboat fabric 0.9T1000D/PVC or 1.2mm PVC, which has excellent air tightness, wear resistance and long service life.
2. Imported air valve is used, which is convenient, safe and reliable.
3. All bonding parts are bonded with imported glue. The peeling strength, high temperature resistance, hydrolysis resistance, UV resistance and other properties are much better than domestic glue. Even under sunlight exposure, the airboat connection parts Robust performance is fully guaranteed.
4. The imported materials have high color fastness, the cloth color remains as new for a long time, and the imported special wear-resistant two-color fenders make the hull durable.
Motor boat hull airbag
Using adhesive and high-frequency heat sealing technology, it has good air tightness, high strength, durability and first-class quality, with a speed of 40 - 60 km/h. It stays inflated for at least a week.
