Abstract: A utility saddlebag which has a top (20), sides (26), and ends (30) and (32), of woven fabric attached together by seams of thread configured to cover the engine compartment enclosure of a jet-propelled watercraft. The saddlebag is held in place by the use of an elastic member (36) sewn into a bead on the skirt or periphery of the device allowing it to be stretched over and held in place by tucking the ends under the edges of the housing. A number of pockets (28) on the sides and on the rear (34) provide storage compartments, and a strap (40) assures closure on the sides. The invention provides storage for a watercraft, without any modification or alteration heretofore unavailable.
