How many passengers must be carried for there to be one radiotelegraph installed on a lifeboat?

The installation of a radiotelegraph on a lifeboat is governed by international maritime regulations, specifically those outlined by the International Maritime Organization (IMO) and related safety conventions. According to these regulations, a lifeboat must be equipped with a radiotelegraph if the ship carries a certain number of passengers. The threshold for requiring one radiotelegraph on a lifeboat is established at 1500 passengers.

This requirement is rooted in the need for effective communication in emergencies, ensuring that lifeboats are equipped to signal for help and maintain communication with the ship and rescue services. The regulation aims to enhance the safety of passengers during evacuation and aligns with overall maritime safety standards. Carrying 1500 passengers or more makes it crucial to have additional communication devices to manage rescue operations adequately and ensure the safety of a large number of individuals.

Thus, for a vessel carrying 1500 passengers, having at least one radiotelegraph on the lifeboats becomes essential to comply with safety regulations.
