As has been stated previously QM2 was specifically designed to “shoot the rapids”. She has a higher quality of steel than regular cruise ships and a much higher freeboard, favourable metacentric height and rolling moment combined with a finer ratio and flared bow - all this means she cuts through the biggest waves and doesn’t roll around in the swell, the downside is that she cost more to build per tonne than any other cruise ship afloat at that time. The only thing I ever noticed was the occasional “bang” as she tames a wave that would have lifted a lesser ship. She is one of a kind, maybe even the last of her kind, but definitely the ship for those poor unfortunates with queasy tummies.
