Abstract

Provided are a fin device and a ship such that slow zones are concentrated on the propeller surface, thereby improving propulsion efficiency and allowing energy conservation. A ship 1 according to one embodiment of the present invention comprises a fin device 2 which is disposed on the ship body provided with a planar side flat 11 that is formed in the ship length direction on the ship side. The ship 1 has two fins (a first fin 21 and a second fin 22) within a region a that is surrounded by a line L1, which connects the stern-side lowest point P1 of the side flat 11 to the intersection Q between the designed waterline DWL and the propeller line PL showing the position of a propeller 12, a bilge height line BHL showing a bilge height, and the propeller line PL.
