In order to promote the healthy development of FRP fishing ship industry, make up for domestic large FRP fishing ship construction technology gap, realize the independent, procedures and standards for the construction of Large FRP fishing ships design in China, complete the "13th Five-Year" fishery development goals, this article based on the Oceanic and continuity characteristics of Large FRP fishing ships as the starting point, introduced the ship type, operating environment, molding method and hull structure, compared with the current domestic construction technology of FRP fishing ships, analysised of the existing defects in the construction technology of FRP fishing ships and the causes of problems in the process of use, according to the characteristics of resin and glass fiber materials and applicability from five aspects of the mold construction form, selection of raw materials, molding technology, the deep connection form of hybrid hull structure and composite sandwich plate and the hull deck, the main points of the technology were expounded in this paper, experimented in the construction of a Large FRP fishing ships, and the application results were good, which laid the foundation for the improvement of the construction technology of FRP fishing boats in China.
