Which statement correctly defines the term "berthing"?

The term "berthing" specifically refers to the process of securing a vessel at a dock for loading or unloading. This is a critical operation in maritime logistics, as proper berthing ensures safety and efficiency during cargo operations. It involves not just the physical act of bringing the ship alongside the dock but also securing it in place using mooring lines, which are vital for maintaining stability and preventing the vessel from drifting. Proper berthing procedures are essential to prevent damage to both the ship and the dock, and they facilitate the smooth transfer of cargo and passengers.

The other choices relate to maritime operations but do not accurately define berthing. Maneuvering a ship to avoid collisions involves navigation skills rather than the act of securing at a dock. Navigating through narrow straits safely is a matter of piloting and route planning, not necessarily related to where the ship is moored. Adjusting a ship’s price for cargo transportation pertains to shipping logistics and finance, which is unrelated to physical docking or berthing practices. Thus, the definition that focuses on securing a vessel at a dock accurately captures the essence of what berthing entails.
