To provide a floating swimming aid having functions of constantly positioning the body of a user swimming with the floating swimming aid in the center of the floating swimming aid, simultaneously applying buoyancy to both of the user and the floating swimming aid by allowing the body of the user to constantly bathe in water during its use, and constantly keeping upward the upper half body of the user.

Rectangular floating board with the smallest buoyancy among floating boards with different buoyancy is longitudinally laid at the center, floating boards with buoyancy next larger than that of the central board are laid on its both sides, and the floating boards are laid so that their buoyancy is increasing from the center towards both end parts. The front parts and the rear parts of the adjoined floating boards are bound to one another respectively by connecting materials and formed into a single float. The lengths of the connecting materials are set short in the front part and long in the rear part, or the buoyancy of the floating boards is arranged so as to be large in the front part and small in the rear part.
