Fluke drive system for a vessel (100), comprising a pivot element (114) having a forward end and an aft end, which pivot element (114) is pivotally connected at the forward end to a hull (101) of the vessel (100) and which pivot element (114) is connected at the aft end to a flexible fluke (125); a driving mechanism having a drive point (120), which driving mechanism is arranged to impart a reciprocal or rotary movement to the drive point (120); and a drive rod (121) having a first end and a second end, which drive rod (121) is connected at the first end to the drive point (120) and at the second end to the pivot element (114), which second end is connected to the pivot element (114) at a point (122) along the pivot element (114) between said forward and aft ends. The invention is characterized in that the driving mechanism comprises a carrier element (112) fastened to a propeller axle (111) of the vessel (100) and being arranged to rotate with the said propeller axle (111), and in that the said drive point (120) is excentrically arranged on the carrier element (112) so that a rotation of the propeller axle (111) will drive the drive rod (122) back and forth, in turn resulting in a reciprocal up and down motion of the flexible fluke (125). The invention also relates to a method.
