The above render comes from a marketing campaign I came across. It shoes how the classic lines of the Titanic will meet modern standards. Note the Lifeboats.

However, I don’t think that’s enough. The stern will need to be redesigned to meet the IMO/SOLAS stability standards. I’m not sure that 2 bow thrusters are enough. I don’t see any X or S band radars. Though those will probably be off of the forward mast. And I’m sure the SatComms will be in the first 3 funnels. That is, if they don’t make those into owners suites.
