Do the rules regarding liquids on planes also apply on cruise ships as well?

I'm planning to take my wife on a cruise next December 2008 for our 10yr anniversary. The rules on airlines require that liquids such as shampoo must be in a 3oz size bottle & that they must be in a clear 1qt size container. I'd like to know if those same security measures that are in place on airlines also apply for a cruise ship too?
The correct answer from someone who cruises regularly is NO.

When you check in at the pier your luggage is taken by a porter to the place where it is put on ship. Luggage goes through its own security check just like at the airport. It is then later delivered to your cabin. With your cruise tickets you will receive luggage tags for your bags and those are used by the ship's staff to get your luggage to your cabin; tags have your name and cabin number on them.

After you check in you and all of your carry on things go through the same type security scanner, with the moving belt, that is used in the airports. However they do not ask you to separate out liquids and tubes of toothpaste. You can carry all of that in your carry on. I usually also carry on a few bottles of water and soft drinks for my cabin and have had no problem with that. However, do not attempt to carry on liquor as it will be picked up by the scanner and they will confiscate it. That is always one of the things that they look for when you first board and when you return to the ship at a port stop.
