The invention aims at providing a high-speed and high-wave-resistant double-sheet-body multi-body planing boat. The planing boat comprises a main boat body and two same sheet bodies arranged on the two sides of the main boat body, and the two sheet bodies are connected with the main boat body through channels with the longitudinal deformation curvature from the portion of which the length is 10% of the boat length to the stern; the sections, in front of the portion of which the length is 50% of the boat length, of the sheet bodies are shaped like a pentagon with obtuse angles and folded edges, the inner side face and the outer side face of each section are cambered surfaces, and the sectional area is gradually increased; the sections, behind the portion of which the length is 50% of the boat length, of the sheet bodies are shaped like a symmetrical pentagon with obtuse angles and folded edges, the inner side face and the outer side face of each section are planes, and the sectional area is invariable. According to the high-speed and high-wave-resistant double-sheet-body multi-body planing boat, the reliability and applicability of the planing boat in a water area with the complex environment can be improved very effectively, and therefore the planing boat can complete various tasks more quickly and more reliably; the planing boat can be widely applied to different sea areas and different environments.
