Abstract:

Apparatus, devices and methods of operating multiple high aspect ratio hydrodynamic horizontal ladder oriented vanes with pliable hinges and rotation limiting flexible webs attached between flexible support beams on swim fins. The fins can have a foot pocket. A pair of parallel support beams can be secured to the foot pocket and support a plurality of hydrofoil vanes in a resisted pivotal arrangement. Pivotal rotation of the vanes can be restricted by flexible membranes, between vanes and beams, to provide an optimum angle of attack for the during swimming. The fins can have at least one pivoting vane region connected to the fin with a flexible hinge member.
