[origin: EP3450299A1] An appendage 8 for reducing a hub vortex is arranged, through a support 7 extending from a hull 2, behind a propeller (wing propeller) 4 having no rudder behind the propeller. The appendage 8 is in the form of a spindle having a circular cross-section in a direction perpendicular to a central axis of the spindle along a hull and having a rear portion with gradually reduced diameters toward a rear end. The appendage 8 has a maximum diameter and a length along a hull which are 10-40% inclusive and 40-70% inclusive of the diameter of the propeller (wing propeller) 4, respectively.
