A method of forming a fin configured for use with a water sports board. The method includes providing a mold having a mold cavity and first and second insert pre-preg sheets each including structural strands respectively bonded by first and second resin materials. The method further includes placing the insert pre-preg sheets within the mold cavity. The method further includes injecting a third resin material under pressure into the mold cavity between the first insert pre-preg sheet and the second insert pre-preg sheet to urge the first insert pre-preg sheet and the second insert pre-preg sheet away from each other and towards respective ones of the pair of mold cavity faces, and dispose the third resin material between the first insert pre-preg sheet and the second insert pre-preg sheet to space at least a portion of the first insert pre-preg sheet from the second insert pre-preg sheet.

An inflatable paddle board includes a board body which is inflatable and a central balancing fin which is configured to be provided at a bottom of the board body, the central balancing fin increases the surface area in contact with the water, so as to provide additional lateral resistance, and this added resistance stabilizes the paddle board, making it less prone to tip over, and also maintain a straight trajectory by reducing the lateral drift.

The disclosure provides a paddle fin structure, which comprises a fin body and a base, wherein the fin body is inserted into and connected with the base through a pin. The pin is adopted to replace the traditional strip wire connection, and the installation and disassembly are convenient. At the same time, the special fin structure is adopted, which can effectively improve the flow diversion, reduce the resistance, improve the water diversion function, and increase the traveling speed.
