Abstract
A swim fin provided with a canal-like member for conveying and controlling the fluid flow produced during each swimming stroke. The fin comprises at least at the central portion of its blade a section which, by dynamical deformation, gives rise to a canal-like fluid flow conveying member on that side of the fin opposed to the side under active stroke. The canal-like member is inverted as soon as the swimming stroke is reversed, so as to perform its fluid flow conveying action during both swimming strokes.
