Can anyone help me with a questions as to the heights of older vs. the newer behemeth cruise ships? The Titantic at 882 ft x 92 ft of beam and 34 ft of draft (46,000 tons) appears to have a height from the keel of 175 ft. The RMS Queen Mary (81,237 tons) 1019 ft x 118.5 ft x 39 ft has a height of 181 ft. I could not determine if the height was from the keel or waterline. I am also unable to find any height, beam or draft for the QM2 at 1132 ft and a rather well endowed 150,000 tons.

Lastly, The Enchantress of the Seas I spotted recently on AIS (Automated Identification System) interestingly indicated its length at .163 nm...first time I'd seen a ship's dimensions expressed as a percent of a nautical mile, doing the math it calculates to 998 ft with a beam of 108 ft, draft of 25 ft and 80,700 tons.

AIS does not provide a vessel height so I have used the Internet to track those down. I have been unable to find measurements for Enchantress' height about water.

I was particularly interested in the post I read on the forum that covered the factors that go into determining a vessel's stability, both initial and as she begins to roll, reading it got me hooked to the point I have registered and look forward to contributing.

My interest is sort of like the old fork tail about the German scientist who determined that bumblebees can't fly, I continue to marvel at how the modern day cruise ship does not just roll over with its 11 or 12 passenger decks and sides that reach to the sky. Of course its beam is well into the average length of the modern day megayacht.

I look forward to any comments forum members may wish to make, posting at 5:00 a.m. no I am not suffering from insomnia, this is coming from the west coast of the United States where we're just wrapping up from a busy Sunday.
