Abstract (en)

A method and apparatus for increasing efficiency of a propeller-driven vehicle, preferably a ship, comprises a stern tunnel and a nozzle (8) wherein the tunnel prevents flow of fluid over the hull from interfering with flow of fluid through the nozzle (8). The tunnel comprises at least one fin (14) which extends along the hull preferably from a point between the hull and the nozzle to a point forward of the nozzle.
