Washington Charter Vessel Inspection is an annual inspection process mandated by the Washington State Department of Natural Resources (DNR) to ensure that charter vessels are safe and seaworthy. This inspection process is intended to protect passengers and crew on recreational vessels operating in Washington waters. Depending on the vessel type, charter vessel inspections may include a Vessel Safety Check, Hull and Machinery Examination, Load Line Certification, and Vessel Stability Test. The Vessel Safety Check is a comprehensive examination of all the vessel's safety equipment, including life preservers, navigation lights, fire extinguishers, and other safety items. The Hull and Machinery Examination is a detailed inspection of the vessel's physical condition and machinery, such as engines, steering systems, and fuel systems. The Load Line Certification is a test of the vessel's load-carrying capacity and stability. Finally, the Vessel Stability Test is a computer-simulated test to determine the vessel's ability to remain upright in various sea conditions.
