A fin mounting system for a surfboard which utilizes a box embedded within the surfboard with the mounting being achieved by producing a through cavity within the surfboard, placing the box within the through cavity and then pouring a hardenable resin between the box and the sidewall of the cavity completely filling such. The box is constructed of a glass filled polyurethane plastic. After the resin is hardened, any portion of the box that protrudes exteriorly of the surface of the surfboard is removed. The fin has a mounting end which is to be transversely snugly received within the box. The fin is adjustable longitudinally within the box. A fastener is employed to fix in position the fin when the desired adjusted position is achieved. The fin is constructed of a glass-filled, nylon material. The fastener comprises a conventional bolt and nut with the nut being embedded within the fin. The fin includes an enlarged recess directly in alignment with the nut which facilitates insertion of the bolt in conjunction with the fin facilitating engagement with the nut. The box may include a leash attachment section.
