The invention relates to a watercraft, in particular a swimming and/or diving aid with a hull (10) having a stern (12) and a bow (11), wherein two flow channels (27) are provided in the hull (10) or on the hull (10), which flow channels extend from a water inlet (22) to a water outlet (24), wherein a water acceleration device (52), in particular a propeller or a propelling screw, is arranged in each of the two flow channels (27), wherein each water acceleration device (52) is driven by a motor (50), wherein handles (31) a user can hold on to are arranged in the midship area between the bow (11) and the stern (12) or in the bow area, wherein a support surface (40) is provided adjoining the handles (31) in the direction of the stern (12), on which support surface the user can at least partially rest, and wherein two spaced-apart bulges extending in the longitudinal direction of the hull (10) are provided on the underside of the hull (10), between which bulges at least one water-sliding surface (14, 15) is arranged. To be able to implement a low flow resistance with a compact structure in such a watercraft, provision is made according to the invention that the flow channels (27) extend at least sectionally in the area of the bulges.
