OK, Russell. You got me. I was transfering my feelings to others, and from years of psychological tests (administering, not taking) I know that can't be done. I will stand behind rolling being easier on the ship than pitching, however. If you are far forward or far aft during pitching, you will experience periods of weightlessness alternating with multiple-g-force weight. That is very uncomfortable for me.

Although we've been on QE2 twice, we were lucky enough to have fair seas. The second time I was anxious because we had to cross the Bay of Biscay but it was only force 5, so no problem (although there were still people suffering from seasickness)

I'm no expert, but does QE2 pitch rather than roll, which makes her more stable in rough seas??

Re the debate over QV, she wasnt' built for regular transatlantic voyages - that is QM2's role, and she has many innovative engineering features to enable a ship of her size and height to cross the Atlantic in safety and at the speed required to maintain the 6 day schedule. There have been several interesting programmes about the building of QM2 and the problems which had to be overcome.

Obviously, QV will have to make the crossing at various times but her primary role is one of cruising, still I don't think I would want to have been a passenger on that particular cruise!

All ships both pitch and roll. If the ship is heading straight into or away from the seas (taking the swells on the bow or the stern), it will pitch. That means the bow is alternately rising and falling. If the seas are being taken on the beam (the side of the ship) it will roll. If the ship is crossing the swells at a 45 degree angle it will pitch and roll at the same time, a situation sometimes refered to as "bucking". Although any violent motion can cause damage to a ship, rolling is less likely to structurally damage the ship than is pitching or bucking. I could go into a discussion of righting moment, center of gravity, center of bouyancy, and some other statistics that determine how much and how quickly the ship will move, but I won't unless somebody wants me to.

Larry, that explanation might well be very helpful...especially to first timers who are unsure about the best cabin position, whether they will be more likely to be unwell with seasickness at certain parts of a ship...and also to help explain why pitching and rolling can be uncomfortable etc.

If you would like to post some sort of explanation in layman terms about the differences, causes and so forth, then please go ahead and do so in the first time cruiser section, please...I am sure many will be interested in why a ship behaves in different ways in weather

Once completed, I will make it a sticky, so that it can be an easy to find reference point

Thanks Larry

Thanks Larry for the explaination

I'm a sit on the deck watching the sea go by person, I'll now be able to look out for the tell tale signs in the waves and swells.

Thanks again

When I,m on a ship that rolls, pitches and corkscrews at the same time ,I don,t want to do anything but lie down.
