摘要

A prolusion device for a vessel, a vessel having the same, and a prolusion device installation method are disclosed. The prolusion device for a vessel according to the embodiment of the present invention includes a rear propeller fixed to a rotary shaft; a front propeller supported by the rotary shaft formed on the rear side of the rear propeller to be rotated; and a reverse rotation device which reverses the rotation of the rotary shaft and transmits the reversed rotation of the rotary shaft to the front propeller. The reverse rotation device includes a gear box which is received in an installation space formed on the rear side of a hull while embedding a plurality of gears which reverses the rotation of the propeller.
