Abstract
An aquatic fin for propulsion of a watercraft including a foot securing section and a blade section. The blade section having a top surface forming a concavity and a bottom surface forming a convexity. The blade section and foot section are joined by side walls and struts which define channels for directing water around the convexity in order to lessen the resistance of the fin moving downwardly and rearwardly through the water and with the upwardly and forwardly movement of the fin the concavity increases the resistance through the water, thereby propelling the watercraft away from the direction the user is facing. The foot securing section including knobs having radially extending oval tips in which latch plates on each end of a cross-strap that extends across the instep of the wearer seat over the knobs and are retained in place by clips on opposed ends of a heel band extending around the heel of the wearer, locking the cross-strap and heel band from detachment from the knobs unless the clips on the heel band are rotated into orientation with the oval tips.
