The invention relates to a vessel which comprises a floating body upon which a seat for a person is mounted. The vessel is driven by human power through a treadle mechanism which drives a propeller. The treadle mechanism comprises two actuating elements which are each pivotable and are driveable by arms or legs and which are coupled by a driving shaft through a freewheel clutch. By avoiding the death centers which are present in a cycle treadle mechanism, human power is used efficiently. By making the floating body a gliding body the water resistance is reduced, so that together with the efficient propulsion mechanism a high travelling speed through the water is reachable. |
