A patrol boat is a small, fast vessel designed for monitoring and enforcing laws in coastal and inland waters. These boats are often used by the military, coast guard, and law enforcement agencies to conduct surveillance, intercept illegal activities, and provide search and rescue operations. Typically equipped with advanced navigation and communication systems, patrol boats can operate in various weather conditions. They may also carry weapons for defense and enforcement purposes. Commonly associated with maritime security, patrol boats play a crucial role in protecting national interests and ensuring safe waterways, often working alongside larger ships and aircraft.
