An emergency paddle kit for sailboards is disclosed. The kit comprises at least one shaft which has a paddle blade attached to one end, which shaft is releasably attached to the boom of a sailboard. When the sail of the sailboard is not used to propel the sailboard through the water, the shaft may be released from the boom and the paddle may be used to propel the sailboard through the water. The emergency kit may further comprise a second shaft which has a second paddle blade attached to one end, which second shaft is also releasably attached to the boom of the sailboard. The first and second shafts may be connected together to form a kayak-type paddle which may then be utilized to propel the sailboard through the water. The emergency kit may further comprise a number of attachments, such as shaft extensions and a paddle handle which may be attached to the shaft and/or to each other.read more
