Abstract:
A propulsion device and a watercraft including the propulsion device. The propulsion device comprises a flexible fluke that is pivotable about a horizontal axis, for propelling a floating watercraft. The propulsion device is adapted for connection to an output drive shaft that transmits rotary motion. The propulsion device comprises a fluke oscillation drive having gear reduction of the rotary motion transmitted by the shaft and a mechanism for converting the rotary motion transmitted by the shaft to oscillatory motion of the fluke.
