The invention discloses a solid boat-body dragon boat. The solid boat-body dragon boat comprises an outer wall, an inner wall and a boat-body keel, wherein the boat-body keel is a cavity structure; a solid layer is arranged between the outer wall and the inner wall; a reinforcing material layer is arranged in the cavity of the boat-body keel; and solid reinforcing points are arranged on ship rails at two sides of a boat body. The molding process comprises the steps of production of molds, production of female molds and male molds by using glass steel molds, surface cleaning of the molds, bonding of dragon scales, spraying of gel coats, foam prefabricating, spreading of the male molds, spreading of the female molds, mold closing and glue injecting, demolding and assembly. The once molding of the male molds and the female molds is realized; the dragon boat is compact in structure, is integrated, and is high in strength; the internal of the boat body is a solid structure, and foams and carbon fibers are used for assisting the reinforcement, so that the whole strength of the dragon boat is reinforced, the safety coefficient is high, and the directivity is good; and the molding process has the advantages of low labor intensity of workers, improvement of working environment, few links of production process, short production period and high working efficiency.
