The swimming aid (1), designed to extend the area of the hand, has holders (21, 22, 23) on one side for the fingers, and a zone (41) to receive the palm, with projections (31, 32) that go over the back of the hand and form a gap for introducing it. The finger holders can be in the form of one or more projections with spaces for the fingers, and variants of the design can have fastening straps or sockets for attaching a sectional bar to convert the swimming aid into a canoe paddle.
