MULTI-SCREW BOAT PROPULSION SHIP PROPULSION enables better maneuverability of the vessel than the classic propeller drive, especially in narrow or overcrowded waters, and in the event of the vessel being propped up for an extreme storm with large waves, at least two propellers always remain in operation, so maneuverability is not lost even for a moment. It contains at least two suitably shaped side recesses in the ship’s hull at the bow and two at the stern, with built-in propulsion units (PJ) according to Figure 2, which form a sealed electric motor with a propeller on the same shaft, fed through a vertical tube (C), embedded and sealed in walls of the cavity and inside the hull above the waterline at maximum draft, which enables turning the drive unit to any angular position within 360o around the vertical axis, by any turning mechanism (worm wheel, chain wheel, etc.)
