What is the common term for the side of the boat that is against a dock?

The term that refers to the side of the boat that is against a dock is "port." In nautical terminology, the port side of a vessel is the left side when facing forward, and this side is commonly used to tie up alongside a dock.

Understanding this term is essential for effective communication among crew members and when giving or receiving docking instructions. The distinction between port and starboard (which refers to the right side) is crucial for navigation and safety at sea, especially since these terms help avoid confusion that could arise from the perspective of different individuals on the boat. The use of "gangway" specifically refers to a movable bridge or ramp used for boarding and leaving a ship, not the position of the boat itself, making it an inappropriate term in this context.

Recognizing these terms promotes clarity in maritime operations, which is vital for effective teamwork and safe vessel management.
