Abstract: The present invention relates to a watercraft attachment device for joining two watercrafts comprising: a pair of parallel tubes, where said parallel tubes are substantially parallel to the watercrafts; a pair of perpendicular tubes, where said perpendicular tubes are substantially perpendicular to the two parallel tubes and adjoin the parallel tubes; four abutting corners, where the four abutting corners are formed by the intersecting tubes; a plurality of hook attachments extending from the each corner, where said hook attachments extend over a lip of each cockpit within the watercrafts to connect the watercrafts to the watercraft attachment device; and at least one tension cord extending from each corner, where said tensioning cords tighten the hook attachments to secure the watercraft attachment device in place.
