Which types of vessels are exempt from the regulations outlined in 33 CFR 155?

Warships and naval auxiliaries are exempt from the regulations outlined in 33 CFR 155 because these vessels are operated by military services and serve national defense purposes. The exemptions for military vessels recognize their unique operational requirements and the need for flexibility in mission execution and emergency response. The regulations in 33 CFR 155 typically apply to civilian vessels engaged in commerce or recreational activities, ensuring that they meet safety and environmental standards. By exempting warships and naval auxiliaries, the regulations acknowledge the distinct nature of these vessels and their operations, which often do not align with commercial maritime regulations designed for civilian vessels.
