The invention relates to a watercraft, in particular a swimming and/or diving aid, comprising a hull (10) which has a stern (12) and a bow (11), wherein: two flow channels (27) are provided in the hull (10) or on the hull (10) and run from a water inlet (22) to a water outlet (24); a water acceleration device (52), in particular a propeller or a water screw, is located in each of the two flow channels (27); each water acceleration device (52) is driven by a motor (50); handles (31), on to which a user can hold, are located in the central region between the bow (11) and the stern (12) or in the bow region; a support surface (40), on at least part of which a user can rest, is provided adjacent to the handles (31) in the direction towards the stern (12); and two spaced-apart bulged portions, which extend in the longitudinal direction of the hull (10) and between which at least one water planing surface (14, 15) is located, are provided on the underside of the hull (10). In order to be able to achieve low flow resistance in such a watercraft with a compact structure, according to the invention the flow channels (27) extend, at least in certain areas, in the region of the bulged portions.

    本发明涉及一种筏、尤其是游泳和/或潜水辅助装置,其具有筏身(10),所述筏身具有尾部(12)和首部(11),其中在筏身(10)中或在筏身(10)处设有两个流动通道(27),所述流动通道从进水口(22)伸展至出水口(24),其中在两个所述流动通道(27)中的每一个中都设置有水加速设备(52)、特别是推进器或推水螺旋桨,其中每个水加速设备(52)由马达(50)驱动,其中将把手(31)设置在首部(11)和尾部(12)之间的中间区域或设置在首部区域中,使用者可以在把手处抓紧,其中沿朝尾部(12)的方向连接于把手(31)设有支承面(40),使用者可以至少部分地支承在所述支承面上,并且其中在筏身(10)的下侧设有两个彼此间隔开的、沿筏身(10)的纵向方向延伸的凸起,在所述凸起之间设置有至少一个滑水面(14、15)。为了在这种筏中在结构紧凑的情况下可以实现低的流动阻力,根据本发明提出:流动通道(27)至少局部地在凸起的区域中伸展。
