    摘要： A sailboard is disclosed of the type having a mast pivotally connected to a board, a boom connected at one end to the mast and a sail tensioned by out haul and down haul lines. A down haul tie down mechanism is provided for receiving and securing the down haul line at a location adjacent to the sailboard pivot. A cup with a special release mechanism is provided for releasably connecting the mast to the pivot. Release mechanisms for releasably interconnecting other sailboard components, such as boom sections and boom extensions, are also disclosed.
