A "dock" is a structure built along the edge of a body of water, like a river or ocean, where boats and ships can be tied up or loaded and unloaded. Docks are essential for transporting goods and people, making them important for trade and travel. They often have facilities for maintenance and storage, helping to keep vessels in good condition. In addition to serving boats, docks can also be places for recreational activities. People often visit docks to fish, enjoy the view, or take a stroll. Some docks even have restaurants and shops, making them popular spots for locals and tourists alike, like those found in harbor areas.
