heal.abstract	The aim of this study is the quantification of the efficiency of eight swim fins, measuring their thrust and transverse (vertical) force via a six-component piezoelectric balance, recording simultaneously their shape along the longitudinal axis. The fins were submerged in a water tank with zero free stream velocity, and were driven through a plunging and pitching mechanism. In the middle of half stroke the measured thrust varied for the examined fins between 11.3 N and 27.8 N and the corresponding vertical force between 55.8 N and 84.8 N. Fins with short, wide blades and stiff side rails proved to be more efficient than those with long, narrow blades of half the aspect ratio. Depending on the stiffness of the side rails and that of the fin blades, the performance of the low aspect ratio blades was very variable.	en
