A transverse propulsion device (1) of a ship (2) comprising a maneuvering tunnel (3) defined in a hull (4) of the ship (2) and adapted to contain at least one maneuvering propeller (5); said maneuvering tunnel (3) being delimited by tunnel walls (6), which extend between a first tunnel entrance (7) and an opposite second tunnel entrance (8); at least one coupling (9), which extends from the tunnel walls (6) at the at least one tunnel entrance (7, 8); at least one support structure (10), comprising at least one counter- coupling (27); said support structure (10) being connected in a separable manner with said at least one counter-coupling (27) thereof to said at least one coupling (9); wherein said transverse propulsion device (1) further comprising at least two closing doors (12) shaped so as to close the at least one tunnel entrance (7, 8), as a whole when in the closing position; said at least one support structure (10) comprises hinges (11); and wherein at least two closing doors (12) are rotatably supported only on said hinges (11) of the support structure (10), and wherein said at least one counter-coupling (27) has a shape which is complementary to the shape of the at least one coupling (9) and geometrically couplable with the at least one coupling (9), and wherein the at least one counter and wherein (27) and the at least one coupling (9) are shaped so that, when they are geometrically coupled, they define a hydrodynamic shape.
