Which side is referred to as port?

In nautical terms, "port" refers to the left side of a vessel when facing forward toward the bow (front) of the ship. This terminology helps to eliminate confusion that might arise from using directional terms such as left and right, which can change depending on the orientation of the observer. The term "port" is consistently used in both maritime and naval contexts, including in the United States Marine Corps, to describe the left side. Therefore, it is important for personnel, especially those who operate in or near water, to understand and accurately use these terms for safety and effective communication on board ships or in amphibious operations.
