Abstract:

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.
