A ship's log is a record maintained on a vessel that documents its journey, activities, and important events. This log typically includes details such as the ship's position, weather conditions, and any significant occurrences during the voyage. It serves as an official account of the ship's operations and can be used for navigation and legal purposes. The log is usually kept by the ship's officer, often referred to as the navigator or captain. It is an essential tool for maritime safety and helps ensure compliance with regulations. In case of emergencies, the ship's log can provide crucial information for rescue operations.
