Abstract

A device (20) for improving propulsion efficiency of vessel includes a plurality of stator fins (P1-S2) arranged radially on the bow side for the bossing (15) of a vessel (10) as compared with a propeller (11). The stator fins (P1-S2) are formed such that the length (ds) from the axial center of the propeller to the end of fin blade becomes 70% or less of the radius (dp) of the propeller (11) when the stator fins (P1-S2) are fixed to the bossing (15). The stator fins (P1-S2) are arranged on the bossing (15) at a fixing angle (φ) of 20°-40°, assuming that the angle made by a plane including the trailing edge of the stator fins (P1-S2) and the axial center of the propeller and a plane including the trailing edge and the chord on the cross-section at the root of the stator fins (P1-S2) is the fixing angle (φ).
