<p>A scuba fin (10) has the fin (20) section separated from the foot pocket (12), and connected thereto by a shaft (22). The shaft (22) has substantial height (38), but is of minimal thickness (40), so that it presents little frontal area to the water. This arrangement enables the scuba fin (10) to pass through water with reduced resistance when swimming. Also, area and mass of the fin (20) are minimized, while still providing an appropriate area to be subjected to water for propulsion. The angle of the fin (20) is offset from the angle of the bottom of the foot pocket (12), elevating the front end of the fin (20), so that the likelihood of tripping is substantially reduced. The novel fin (20) reduces effort by a scuba diver, thus enabling increased bottom time, and enables more convenient and confident walking on boat decks or on terra firma.</p> |
