On Thursday, January 31, 2002, we ventured below the waves in one of the Atlantis submarines. The very rough ride in a speedboat from St. Thomas out to the submarine launch site made the kids a bit queasy, the only time on the entire cruise that was the case. The submarine ride itself was very smooth and the ship was well-designed for its purpose. There were no more than two people assigned to each of the two-foot portholes, so there was no need to negotiate camera or viewing angles.
