Having a USCG Checklist is essential for mariners and boaters to ensure their safety while out on the water. The checklist provides a comprehensive list of items and tasks that should be completed before departure, as well as during and at the end of each voyage. Having an up-to-date checklist helps to ensure that all necessary steps are taken for a safe maritime experience. Additionally, it can help mariners avoid fines or penalties for not following regulations and prevent unnecessary accidents.
