A sports board, particularly a body board, for surfing purposes, which board is a preformed, preshaped foam board composed of closed-cell foam material, with an inner core of low density foam material and an outer core of foam material of greater density than the inner core. The board has a top and bottom surface and two sides, the sides containing outwardly extending angular side rails thereon, extending from one to the other end of the board, and around the front of the board. The board includes an integral thermoplastic polymer film material heat-laminated only to the bottom surface of the board, and to the lower side rail surface of the board. The polymer film material provides a low-frictional bottom surface and lower side rail surface and provides for enhanced mechanical stiffening of the board. A method of producing a sports board, particularly a body board for surfing purposes, which method includes applying a solid thermoplastic polymer film material from a roll form, cutting the material to size, and then heat-laminating the material, both to the bottom surface and lower side rail surface of the board, the film material characterized by having a low-frictional type, smooth gliding surface.
