ABSTRACT:
A breakaway surfboard fin holder is provided which is used in conjunction with a surfboard having a fin supporting channel mounted in the lower, rear surface of the surfboard. A fin is provided having an anchoring tongue extending rearwardly along the top of the fin. A support pin is carried by the anchoring tongue and slidably engages elongated grooves formed in the channel. A breakaway tab is carried by the forward portion of the fin so that, when the fin strikes an obstruction, the breakaway tab fails at a predetermined level of force so that the fin itself is not damaged, but may be reused by insertion of a replacement tab and remounting of the forward portion of the fin in the fin supporting channel.
