Which type of vessels must carry a minimum of two SARTs?

Cargo ships over 500 tons are required to carry a minimum of two SARTs (Search and Rescue Transponders) as part of their safety equipment. This regulation is in place because larger vessels have greater operational capacities and responsibilities, making them more likely to be involved in maritime incidents where SARTs can play a vital role in locating them during search and rescue operations.

SARTs are critical communication devices that, when activated, transmit a signal picked up by nearby rescue vessels or aircraft, indicating the presence of distress. This capability is especially important for larger vessels which may traverse vast areas where search efforts need to be efficient and effective.

In contrast, smaller cargo ships under 300 tons, fishing vessels, and yachts may not have the same regulatory requirements or operational needs for additional SARTs, focusing instead on complying with the minimum safety equipment necessary for their size and specific operational environments. Therefore, the requirement for two SARTs is specifically geared towards ensuring that larger vessels, which could potentially carry more cargo and encounter more serious emergencies, are better equipped for emergency situations.
