TRACTOR TUGS can vector thrust in different directions than
traditional boats that use a simple propeller and rudder system.
Although conventional boats exhibit greater efficiency on long
hauls, tractor boats can direct their thrust sideways, offering
benefits in maintaining tension on lines during tight transits and
other harbor and piloting operations. This is achieved through
Z-drives or
Voith Schneider propeller systems.

about how a tractor tug can save the day when a 100,000 ton ship
suffers a rudder failure. Click
