See how the MirageDrive “sails” flex and take the shape of a propeller blade, then reverse their shape on the opposite stroke. This sweeping action (versus a complete revolution as with a standard propeller) allows the MirageDrive to utilize large, powerful blades in a shallower configuration.

You can also use very short strokes, with the blades against the hull, to propel the boat through shallow water. The blades can be “tucked up” against the hull for beach landings.
