Bow/Stern Thruster
The fixed tunnel thruster: a propeller inside a transverse tube through the hull, pushing the bow or stern sideways. Unlike the retractable azimuth unit, it gives thrust in one axis only but has no moving seal exposed to the sea.

What makes this type
The standard bow or stern thruster is a propeller mounted inside a fixed transverse tunnel that runs through the hull below the waterline. Water is drawn in one side of the tunnel and expelled the other, pushing that end of the ship sideways. Unlike a retractable azimuth thruster, it produces thrust along a single axis only, either to port or starboard, and cannot rotate to give thrust in other directions. In exchange it is mechanically simpler: there is no strut to raise or lower and no rotating pod seal exposed to the sea, which makes it the lower-maintenance choice where full azimuthing capability is not required.
Main components
Tunnel
A steel tube built into the hull, with rounded or flared openings on each side to reduce flow losses and cavitation noise as water passes through.
Propeller
Fixed-pitch or controllable-pitch, driven directly or through a right-angle gearbox from a motor mounted vertically above the tunnel inside the hull.
Drive motor
Electric motor on most vessels, sized for intermittent duty since thrusters are typically used only during berthing and manoeuvring rather than continuously.
Seals and shaft
A shaft seal where the drive shaft passes from the dry motor space into the tunnel, the main point where water ingress can occur on this type.
Selection / Sizing
- Thrust output in kN, sized against the vessel's windage area and the manoeuvring performance required in the expected berthing conditions.
- Tunnel diameter, set by the propeller size needed to reach the target thrust without excessive tip speed and cavitation.
- Fixed-pitch versus controllable-pitch, trading mechanical simplicity against faster, smoother thrust response.
- Duty cycle rating of the motor, since most vessels use the thruster in short bursts rather than continuously.
Typical faults
- Shaft seal wear — slow water ingress into the motor space, often first noticed as bilge alarms near the thruster compartment.
- Propeller damage from debris drawn into the tunnel — vibration and reduced thrust, sometimes an unbalanced shaft.
- Motor winding failure from intermittent duty overheating — total loss of thrust on that unit.
- Corrosion at the tunnel grating or flared openings — increased flow noise and reduced thrust efficiency over time.
What to look for in a supplier
- Thrust and current draw figures verified against the vessel's actual electrical supply capacity.
- Seal design and access arrangement for replacement without drydocking where possible.
- Match to the existing tunnel dimensions if the unit is a replacement rather than a new installation.
Check the tunnel grating for debris and marine growth before every port call that will rely on the thruster; a partly blocked tunnel loses thrust long before the motor shows any sign of strain.
