Question 1515 Deck Safety

The correct answer is B) Each lifeboat must have a launching appliance. This is correct because the regulations for cargo vessels require that each lifeboat be provided with its own launching appliance, such as a davit or other mechanical means of launching. The regulations do not restrict the number of launching appliances on a single deck, nor do they require the use of gravity-type launching appliances specifically. The other answer choices are incorrect because they do not accurately reflect the regulatory requirements for lifeboat stowage on cargo vessels. There is no limit on the number of launching appliances per deck, and gravity-type appliances are not mandated by the regulations.
