Do cruise ships have to have lifeboats for everyone on board?

Yes. This rule was actually put into place after the horrors of the Titanic. All ships must have enough lifeboats for everyone on board.

Yes my girlfriend thought after titanic 3D that we should tell new ship companies that they must get enough lifeboats. She works for the prison service, so she is comfy with things that have not changed in 100 years. xx Every boat must cater for all, in the event of lifeboats deployed.
