Abstract:
1. A multiple-serial-hydrodynamic swim fin apparatus comprising: a) a planar blade having a first end and a second end forming a rigid forebody and a flexible afterbody with a left side and a right side wherein a center line extends from the first end to the second end equidistant from the left side and the right side of the planar blade; b) a foot pocket attached to the planar blade in the proximity of the first end and the rigid forebody of the planar blade; c) a tail fin extending from the proximity of the second end of the planar blade where by the tail fin has a left side airfoil portion and a right side airfoil portion of the tail fin conjoined; d) at least one left side fin whereby the left side fin is positioned on the left side of the planar blade between the first end and the second end of the planar blade wherein the side fin is an airfoil; and e) at least one right side fin whereby the right side fin is positioned on the right side of the planar blade between the first end and the second end of the planar blade wherein the side fin is an airfoil.
