ABSTRACT:
A fin for a watersport board, such as a surfboard, includes a substantially rigid core covered by a flexible core covering. The core may include one or more positioning members located on either side surface of the core. The core covering may be formed over the core without covering the positioning members. The fin may include a board coupling assembly that includes a plurality of plugs that each have a lumen lined with material of the flexible core covering. The board coupling assembly may secure the fin to the board by compression forces between a screw and the lining of the plug lumens. Methods of making and using such a fin are also disclosed.
