This is the DOL-Fin, a new hydrofoil monofin swimming system for SCUBA and freediving. The DOL-Fin uses high aspect ratio hydrofoil based monofin technology, which results in very efficient swimming propulsion.
The DOL-Fin is a simple, lightweight, robust and maneuverable monofoil architecture. Compared to other flapping hydrofoil swimmer propulsion systems such as DARPA's PowerSwim (based on the Aqueon), and the Lunocet, the DOL-Fin has advantages which we think will make it the preferred hydrofoil based swimmer propulsion system.
