The FRP shipyard began to appear in the late 1950s and early 1960s, which was another major change in the history of fishing boats. At present, there are more than 2 million FRP ships in the world, not just from the United States? ,? And other developed countries, as well as developing countries in India? Thailand. Practice has proved that FRP is an ideal material for building small and medium-sized fishing boats. Therefore, many countries take measures to limit the production of wooden boats and formulate preferential policies to support the development of glass boats.

Almost all fishing boats caught off the coast of the United States are made of FRP. All wooden fishing boats were eliminated. More than 200,000 tons of FRP are used in shipbuilding every year.

Japan's FRP shipyard has the fastest growth of fishing boats. By 1995, the proportion of wooden fishing boats was only 1 1. 1%, and the glass was basically replaced by FRP in FRP shipyard.

South Africa is the first country in the world to build a larger FRP shipyard. ? 1960 built a 20.7-meter-long PVC sandwich trawler with a displacement of 95 tons. Speed 1 1 nautical mile.

India had 20,000 FRP mobile fishing boats in 1980, and more than 2,500 boats were updated every year.

Peru? The development of FRP fishing boats in Poland and other countries is also relatively fast. A large number of FRP trawlers? Seine fishing boats of 28 inches and below have been produced and sold abroad.

England? France? Germany and others have also built steel fiber ships. Due to the need of environmental protection, logging is restricted all over the world, and the economic benefit of FRP fishing boats in FRP shipyards is better than that of wooden boats. Therefore, it has become inevitable to replace wooden fishing boats with FRP fishing boats abroad.

FRP has low density, high strength, smooth surface, low water absorption, low thermal conductivity, seawater corrosion resistance and is not suitable for maintenance. It can be used to build fishing boats and reduce the weight of the hull by 20%. ? 30%, increasing the load of fishing boats, reducing resistance, increasing speed, saving fuel, improving economic benefits, and being beneficial to fish preservation, easy for mass production, low maintenance cost and long service life.

In addition, the ship designed by FRP shipyard is far from the center of gravity, with large restoring torque, good stability and large wind fluctuation. The security is very good. The development of modern science and technology and the experience at home and abroad have proved that FRP fishing boats in FRP shipyard have many advantages that wooden fishing boats do not have, especially the performance displacement. Speed? Loss of horsepower? Moldability, more non-wood fishing boats can be compared, so FRP is considered as an ideal building material for fishing boats.
