Farol Island at Copacabana/Leme.

A tugboat (tug) is a boat that maneuvers vessels by pushing or towing them. Tugs move vessels that either should not move themselves, such as ships in a crowded harbor or a narrow canal, or those that cannot move themselves alone, such as barges, disabled ships, or oil platforms. Tugboats are powerful for their size and strongly built; some are ocean-going. Some tugboats serve as icebreakers or salvage boats. Early tugboats had steam engines; today diesel engines are used. In addition to towing gear, many tugboats contain firefighting monitors or guns, allowing them to assist in firefighting duties, especially in harbors.
