Queen Mary II, is 30 knots capable. That's the same speed as a modern aircraft carrier. They could pretty much have a drag race. Passenger vessels have typically been record setters for transatlantic trips for the vast percentage of our recorded history.
An Ocean Liner is fast, has good range and will leave most cargo vessels for dead. Frontier has about as much grasp of maritime history and the performance of her many and varied ship types, as pretty anything else at this point. As do, perhaps, a fair few people commenting.
Elite ships are based on actual oceanic ship classes. Beluga is basically the QM II of her day. It should be fast, luxurious, very good range. I guess one out of three isn't bad, I suppose?
