Main characteristics of FRP fishing boats

2022-09-05

FRP has the characteristics of light weight, high strength, corrosion resistance, aging resistance, and strong design ability. The FRP fishing boat makes full use of the characteristics of the FRP material, making it better than the steel and wooden fishing boat in terms of ship performance and economy.


a. Ship performance

The hull of the FRP fishing boat is formed once, the hull surface is smooth, and the resistance is small. Compared with the steel fishing boat with the same power and the same scale, the speed can be increased by about 0.5~1 section. The proportion of FRP is 1 / 4 of steel, the ballast center of gravity of FRP ships is low, compared with similar steel ships, in the case of other parameters remain unchanged, the swing cycle of FRP ships can be shortened by 2-3 seconds compared with steel ships, good float in the wind and waves, strong recovery ability, relatively wind resistance is enhanced.


b. Economy

FRP fishing boat energy saving effect is good. FRP has good heat insulation, the thermal conductivity is only one percent of the steel; compared with other material fishing boats, the ice saving can reach 20%~40%.

FRP fishing boat speed is fast, so it can shorten the sailing time, improve the sea rate, increase the fishing voyage, to achieve the purpose of fuel saving.

FRP fishing boats have a long service life.

FRP fishing boats have good corrosion resistance, the hull will never rust, theoretically have a service life of up to 50 years, and if no damage does not need to be maintained like a steel ship every year.

FRP fishing boats have the characteristics of energy saving, long service life and low maintenance cost. Although the one-time investment is 15%~25% higher than that of steel ships, the long-term economic benefits are still higher than that of steel fishing boats.


Development situation of Chinese and foreign FRP fishing boats


FRP fishing boats have developed very rapidly since the construction of their ships began in the 1950s. It is understood that the United States, Japan, Russia, the United Kingdom, France, Germany, Canada, Spain, Sweden, South Korea and other countries and China's Taiwan province small and medium-sized fishing boats have been eliminated wooden fishing boats, to achieve glass toughened.

The United States was the first country in the world to use FRP fishing boats.

The development of Japanese FRP fishing boats began in the 1960s, and from 1970 to 1980, Japan entered into the period when FRP fishing boats were developing rapidly.

Taiwan in China in the early 1970s began to follow the Japanese research and development of FRP fishing boats, the introduction of Japan, American FRP fishing boat manufacturing technology, by 2010 has successfully built more than 100024~40 m ocean FRP tuna fishing boats, the ownership of the world first, control the world ring equator belt tuna rope fishing operations,

The development of FRP fishing boats in mainland China began in the 1970s. In July 2018, China's first two self-built ocean FRP ultra-low temperature tuna longrope fishing boats "Longxing 801" and "Longxing 802" successfully set sail.
