Abstract

A heel mounted reversible fin assembly for propelling kick boats and float tubes in water. The assembly includes a base mounting mechanism (1) which secures the assembly on a user's boot heel, and an inter-connected generally perpendicularly inclined fin member (4) which extends below the user's boot sole. Apertures (52) extending through the fin blade (50) adjacent to cleavages (46) in ribs (47) define a hinge portion (49) about which the blade (50) flexes to feather on return kicks in the direction of the rear surface (48) of the blade (50). Raised ribs (47) extending generally perpendicularly outward from the rear surface (48) of the fin blade (50) inter-connect, providing a stop mechanism to retain the blade (50) in a generally rigid configuration on power kicks in the direction of its front surface (51). The deep under sole position of the fin blade (50) and flexure limiting ribs (47) co-operate to provide a 'quiet' stealthy progress in water without the rebound splashing (SPL) and surface disturbances caused by conventional fins. In the preferred embodiment the mounting member (2) and fin member (4) are separate inter-connecting components by which the fin member (4) is reversible on the mounting member (2) to selectively propel either in a forward or backward direction.
