Patent ID: 8808043

Claim:
A system for mounting a rigid fin on an undersurface of an inflatable surfboard comprising: an outer mounting body made of semi-soft or pliable material formed with an upper housing portion raised from a base elevation to a raised housing elevation of said mounting body, and with an outer flange portion having an upper surface tapering from the base elevation of the housing portion to outer peripheral edges of said mounting body, said mounting body further having a planar undersurface made of the semi-soft or pliable material and adapted to be mounted with an adhesive to a flexible or curved surface, and an inner mounting insert made of rigid or non-pliable material that is molded into the semi-soft or pliable material within a volume of the housing portion defined from its base to raised housing elevation so as to be held immobile by said outer mounting body, said inner mounting insert having an upper surface provided with a recess for receiving and securely fastening therein a rigid or non-pliable insert member of a fin to be sturdily mounted on the flexible or curved surface, wherein said outer mounting body is formed in a flat elliptical shape with the raised housing portion extending longitudinally along a major axis of the elliptical shape, and wherein said inner mounting insert has a pair of tab slots formed in its upper surface arranged in-line longitudinally along the major axis of the elliptically-shaped mounting body for receiving corresponding in-line tabs on the rigid or non-pliable insert member of the fin and securely fastening them therein.
