How many lifeboats are required on passenger ships carrying 30 or more people?

On passenger ships carrying 30 or more people, the International Convention for the Safety of Life at Sea (SOLAS) stipulates specific requirements for lifeboats. For such vessels, at least one lifeboat must be provided that is capable of accommodating all persons on board. This is the minimum requirement to ensure that there is at least one means of evacuation available to passengers in case of an emergency.

It's important to note that while one lifeboat is the minimum standard, many vessels may actually carry more than one for added safety and redundancy. However, the key point in this case is the regulatory requirement that mandates at least one lifeboat for passenger ships of this size, fulfilling the fundamental principle of safety at sea.
