Titanic wasn't, and was never meant to be a cruise.
As a little sproggie I crossed the Atlantic by liner many times, New York to Southampton and New York to Liverpool, and reverse.
My parents often went up the St Lawrence to Montreal either from Southampton or Le Havre.
We most were on Cunard boats, but also French and US.
I have vivid memories of many of the voyages, both positive and negative.
I can tell you this much, and for no money, that crossing the North Atlantic comfortably and enjoyable depends almost entirely on the season.
When the gales get up no ship with no matter how computer controlled their stabilisers are is completely comfortable.
I have the most vivid memories of an eastbound run in December one year on the SS United States. The damn thing was made of aluminum (aluminium) and creaked and groaned on a duck pond, so was all sorts of noisy in bad weather. This was at a time of strong competition for the Blue Riband and the United States could go as fast as any of them. So was the Captain's response to Force Nine gales and 40 to 60 foot seas to slow down? Hell no. Just blast through. There's a reason that the corridors all have velvet ropes along both walls.
By the way, the force and then the force number.
