A harbor is a sheltered body of water where boats and ships can be docked. It is a place where cargo can be loaded and unloaded, and where passengers can embark and disembark. Harbors often have piers and wharves, which are structures built along the shoreline to facilitate the movement of people and goods between the land and the boats. In addition to commercial activities, harbors can also be recreational areas, with marinas for pleasure boats and yachts.
港口是一个可以为船只提供遮蔽的水域。它是货物可以装载和卸载，乘客可以登船和下船的地方。港口通常有码头和泊位，这些结构沿着海岸线建造，以便于人员和货物在陆地和船只之间移动。除了商业活动，港口也可以是休闲区域，有供游艇和帆船停靠的游艇码头。
