Rocking in bad weather

this will be My third and my wife's first. She is concerned with the rocking of the ship (allure of the seas) in bad weather. Would anyone know if the size of the ship matters?

TG,

A bigger ship will rock less then a smaller one. The ships are equipped with stabilizers to lessen the rocking in bad weather.

You could also get a cabin on a lower level, mid ship. There will be less rocking in those cabins.

Good luck.

Enjoy your cruise.

Welcome to Cruise Critic.

Book a cabin mid-ship and lower on the ship. Most ships will take the stabilizers off during the night.

If you wife is concerned about the rocking of the ship, have her check with her doctor about what medication would be best for her to take for sea sickness.

Spot on!

Really? If the ship is in port during the day, and doesn't use the stabilizers at night, when DO they use them? Actually, use of the stabilizers will depend on several factors: wind and wave direction in relation to ship's course, vessel motion without the stabs, and the speed needed to make the next arrival. While the faster the ship goes, the better the stabs work, they do cause drag which will affect speed and fuel consumption. And while a larger ship will respond less to smaller seas than a smaller ship, the larger ship will be have a higher center of gravity and will therefore roll faster (though through a smaller arc) than a smaller ships, and will be affected by wind induced heel (leaning away from the wind) due to the larger "sail" area that the ship's side presents.

But, yes, a lower cabin and midships will be best.

If you keep your BAC at all times above 0.08 % you won't feel any movement. :D

We like the way you think!:p

That is TOO TRUE!

Bit once sea sickness sets in, you don't want to be low in the ship. (As told to me by my 25 year Navy veteran dad. )

Not true

The moving moment on a ship is a set height so that the ship self rights which means yes it's higher but no different or better than a small ship relative to the moment caused of that height over breadth if ship

This is why the large ships are Aluminium above a set point to keep the centre of gravity low

me thinks one is not understanding metacentric height

but my opinion is only based on three times attending a "damage control for Captains school" ....

The metacentric height (GM) is a measurement of the initial static stability of a floating body. It is calculated as the distance between the centre of gravity of a ship and its metacentre. A larger metacentric height implies greater initial stability against overturning. Metacentric height also has implication on the natural period of rolling of a hull, with very large metacentric heights being associated with shorter periods of roll which are uncomfortable for passengers. Hence, a sufficiently high but not excessively high metacentric height is considered ideal for passenger ships.

Note the last line .... a sufficiently high but not excessively high metacentric height is considered ideal for passenger ships

A destroyer is built with a BIG GM ... it SNAPS to attention when it rolls. Very stable and not very comfortable for others. A small GM means a sllllooooowwwww roll .... and that's comfortable .... but for stability BAD BAD BAD ......

I've seen folks mention how their cruise ship rolled 50, 60 70 degrees ... "my port hole was under water"

wanna guess what the damage is in this condition?

Hi Glenn,

I am sometimes sensitive to motion and am very aware when things get rough. On my 3 cruises there's only been a couple nights where it was rough. How I handle it is I go to my doc and get these round patches I put behind my ear. But put it on either. The night before or the morning of cruise.it seems to work.dont wait till after you feel sqweemish.mid ship is good less rocking. Like everyone has said these mega ships have stabilizers. 90 percent of the time it's like sitting in your living room. My last cruise we did a 4 nighter and an interior room (my first). I'm claustraphobic too.the last night I was kept up by the motion. I got up went to casino till 2 a.m. And then back to room. It was just as bad. I went up by the pool and got fresh air and watched the hard workers clean the pool area.a couple cocktails will help you sleep too.with this all said I truly love to cruise ,the great people you meet,great food and fun times far outweigh the little roughness you will experience..Larry

Welcome to Cruise Critic!

It's very likely your wife won't get seasick. Most people do not. :)

On Oasis (sister ship) we felt little if any motion even at night with the

stabilizers off and the ship going faster.

Not to hijack the thread, but I'll put my two cents back in, though my naval architecture class was 40 years ago.

http://upload.wikimedia.org/wikipedia/commons/thumb/c/c9/Metacentre.png/220px-Metacentre.png

In the diagram, the metacenter is the "pivot" point that the center of buoyancy oscillates around. So, saying that the metacenter is the same for large and small ships is not correct, as each ship has a different center of buoyancy, and the center of buoyancy moves according to the hull shape, and the actual displacement at the time (more ballast, fuel, water, booze, and people submerges the hull more, giving a different center of buoyancy). The period of roll is determined by the righting arm that wants to bring the ship back to upright, which is the difference between the center of gravity and the metacenter. This is metacentric height. So, again, the center of gravity will shift with the actual load in the ship, changing the metacentric height from one voyage to the next. As Capt_BJ states, Naval vessels tend to be narrow hulled (for high speed), giving a high metacenter, and have a low center of gravity, giving a large metacentric height, causing snap rolls. A large container ship or tanker, with a wide beam, will have a lower metacenter, and a higher center of gravity, giving a lower metacentric height, and slower rolls, with less righting arm, so the ship hesitates when over on her beam ends. Passenger ships tend towards the middle of the road as to metacentric height.

Get the sea bands ..

I'm a fan of SeaBands, too.

And tell your wife to pack a pair of flats along with those stilletos she might want to be bringing for formal night. She won't want to be wearing high heels if there's a lot of motion on formal night. On Mariner when we were skirting Hurricane Jeanne everyone was "wall-hugging" down the corridors due to the ship's motion. Wished I had the flats then to go with my sparkly dress. :o We also had a bit of motion as we pulled out of Skagway due to an approaching storm. SeaBands didn't help then. Had to skip dinner and go to bed.

We would just add that bad weather and a rocking ship may not always go together. It is the "long swells" that can make the largest ships "rock" and long swells are caused by big storms which can often be hundreds of miles from the ship. So you could be cruising on a gorgeous day, with little wine, no clouds, nearly no waves, and still get "rocked" by these swells. We have been in seas where the wave height was below 1 meter, but the long swells moved our ship like a toy top. In fact, large stabilized ships handle waves quite well (when they bother to use their stabilizers) but nothing can stabilize against a big swell.

Then why do I have to hold onto the floor so I stop falling off the planet?

And while I'm not moving, why is the room spinning? Please tell Room Service I ordered _Blue_ elephants-- have them take those pink ones back!

Those Blue Elephants are not a problem until you see them walking up the walls and across the ceiling. Oh my!

Gotta love auto-correct:p

Seas are never bad until they tape the bags to the walls.;)

If she starts to feel sick-- tart green apples, soda crackers and clear soda will help. Beforehand there are many OTC prescribed meds to help. Also things that aren't meds-seabands, ginger etc.
