Harbor tug services provide powered assist vessels to guide large ships through confined port waters during berthing, unberthing, and repositioning maneuvers. Port authorities in many jurisdictions mandate tug assistance above certain vessel tonnage thresholds or under adverse tidal and weather conditions. Modern tugs are equipped with azimuth thrusters or Voith-Schneider propellers, delivering exceptional pushing and pulling capacity within tight fairways. Fees depend on vessel size, deployment duration, and the number of tugs involved; they are recorded as a standard line item in the vessel's port disbursement account. Harbor tugs are distinct from ocean-going salvage tugs, which assist stricken or disabled ships on the high seas.
