Repairs being performed on the bow thruster of the Bro Elizabeth. Positioning thrusters come in applications, Bow thrusters at the forward end of the vessel, and stern thrusters mounted aft on the boat. Their purpose is to maneuver or position the boat to a greater precision than the propulsion device can accomplish.
These bow thrusters, also known as tunnel thrusters, may allow the ship to dock without the assistance of tugboats, saving the costs of such service. Ships equipped with tunnel thrusters typically have a sign marked above the waterline over each thruster on both sides, as a big cross in a red circle: ( ⨯ ) .
Azimuth thruster, pod underneath a ship, instead of a propeller and rudder; Bow thruster, or stern thruster, at the bow or the stern of a ship or boat; Rim-driven thruster, electric motor and propeller combined in single unit; Underwater Thrusters, electric motor or hydraulic motor and propeller combined in single unit to propel the ROV, AUV or UUV
The tendency for a propeller to push the stern sideways. In theory, a right-hand propeller in reverse will walk the stern to port. prow 1. The forwardmost part of a vessel's bow above her waterline. 2.

The bow (/ b aʊ /) is the forward part of the hull of a ship or boat, [1] the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. [2] Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline.
Vertical transom and stern of a modern cargo ship. In some boats and ships, a transom is the aft transverse surface of the hull that forms the stern of a vessel. Historically, they are a development from the canoe stern (or "double-ender") wherein which both bow and stern are pointed. Transoms add both strength and width to the stern.
A "ram" bulbous bow curves upwards from the bottom, and has a "knuckle" if the top is higher than the juncture with the hull—the through-tunnels in the side are bow thrusters. [1] A bulbous bow is a streamlined flaring or protruding bulb at the bow (or front) of a ship just below the waterline.
Transverse Thrusters are installed in the bow or stern of a vessel in order to improve maneuverability. Depending on the type of vessel, the range of application for Transverse Thrusters extends from harbor maneuvering to positioning tasks offshore. The units can be installed either with a horizontal or vertical motor flange. [6] [10] [11]
