Abstract
Abstract A fin for a surfboard has a longitudinal fin base. A fin holder in the underside of the surfboard defines an elongate channel extending lengthwise of the surfboard for receiving the fin base for lengthwise adjustment of the fin relative to the surfboard. A clamp is slidable lengthwise in that channel and is engageable with the fin holder and the fin base for releasably retaining the fin relative to the surfboard.
