The beneficial effect of the present invention is, the present invention has the flat plate type composite material rowing boat of balance board, comprises kayak, adopts plate type plastic foam, cuts both sides of plate by simple tool, makes solid core material boat body. Electric heating wire or sheet is used for cutting in this process, the equipment is simple, the processing speed is fast, the cost is low, the weight is light, it is not submerged, and the safety is high. The foam core material is made of glass fiber cloth sewn into a set. The process is low in labor time, low cost and neat in appearance. The inner and outer parts of the cloth cover are coated with resin and then wrapped around the core material, and then wrapped with a plastic film on the outer periphery to cure and form. This process does not require a mold, which saves the cost of mold manufacturing and the man-hours spent on laying layers in the mold. After that, a sleeve made of elastic fiber cloth is used, and the sleeve is installed outside the cured boat. This process does not require gel coat, no painting, no grinding, repairing, and re-grinding, and no grinding dust and water pollution during grinding are generated. Synthetic fiber cloth is easy to dye and has bright colors. It can also print pattern trademarks, and computer embroidery trademarks and fonts.
The cockpit on the hull is made of waterproof fiber cloth sewn into the cockpit cover, which is low cost, light weight, small in size, easy to transport and store; a balance board is set behind the cockpit, and the balance board is higher than the set distance from the water surface. This setting does not affect the normal operation. The rowing speed, because the setting is in the air, when the boat body is inclined to the set angle, the end face of the balance plate is immersed in the water to generate a reverse force, so that the boat body is restored to balance. Because of the balance device, the boat body can be made narrower. thereby increasing the speed.
