Abstract
Improvements in the propulsion system of ships, characterized by the fact of establishing the propulsion organs of the ship, inside the hull thereof, below the waterline, aligned and directly attacked by the motor shaft, centered this axis common with the central and longitudinal plane of the ship's symmetry; enclosing said propulsion organs in a tubular envelope, bifurcated forward in front of the propulsion organs and aft and towards the sides of the ship behind them; keeping all this tubular set below the waterline, inside the hull and perfectly tight in relation to it.
