Abstract
A swim fin having manually articulable water-channeling vanes. A swim fin attachable to a human extremity such as a foot has a front portion through which a plurality of holes are present. Circumscribing these holes are corresponding clock washers that provide intermittent stops when engaged by a complementing clock washer. Such a complementing clock washer is present in a water channeling vane that is affixed over the clock washers of the swim fin by a bolt that passes into a bore (which may be threaded) within the vane. Upon full threading of the vane upon the bolt, the complementing and opposing clock washers come into close contact with one another whereby the ridge of one clock washer fits into a corresponding furrow of the other. The vane is then temporarily locked into place with respect to the swim fin, however this temporary lock is overcome by rotational pressure generally available from a human hand. An alternative embodiment, the swim fins may be retrofitted for affixation of such water channeling vanes by means of a template in which holes are present that correspond to the appropriate position for holes in the swim fin. Clock washers may be attached as by adhesive to …
