Tugs, or tugboats, are powerful vessels designed to assist larger ships in maneuvering through tight spaces, such as harbors and canals. They are equipped with strong engines and specialized towing equipment, allowing them to push or pull ships safely. Tugs play a crucial role in maritime operations, ensuring that vessels can dock and undock without incident. These boats come in various sizes and types, including harbor tugs and ocean-going tugs. Harbor tugs are typically smaller and used for short distances, while ocean-going tugs are built for longer journeys and can handle larger ships. Tugs are essential for maintaining safe navigation in busy waterways.
