Ever been inside of one of those? I've been on Alabama and Massachusetts; the work of designers and engineers astounds me! The miles of wires alone fascinate me, much less the size and purpose of these behemoths!

never had the in-person experience. looking forward to it one day soon.
There are several around the country, so the possibilities are good: Iowa in San Pedro, CA, Alabama in Mobile, Missouri in Honolulu, Massachusetts in Battleship Cove, border of Mass. and Conn., The Texas will be open again soon (only WWI Dreadnought still in existence), and some others. Have fun!

I saw the Blue Angels at Point Mugu flying the F-4. It was literally earth shaking.
I also saw Vandy 1 of VX-4 many times as an F-4 and F-14, and actually got to install and integrate some instrumentation gear in the F-14D Vandy 1.

Always freaky to see!
Tiptoeing into the 'Jet Age' - an Avro Lancastrian (Airline variant of the Lancaster) with a pair of Armstrong-Siddeley Sapphire turbojet engines. As the war drew to a close, orders for Lancaster bombers were cancelled and Avro was left with a number of partly completed aircraft.
Rather than scrap these, it was decided to re-purpose them as airliners, identified as the Avro 691 Lancastrian. This was very similar to the Lancaster XPP, with all turret openings faired over and a new streamlined nose and tail being added.

Year later, and $2 billion spent, she's open for business.
Cruises ain't my thing, but my mid-thirties kids can't wait to suit up for this thing.

I’m sure a lot of aluminum, carbon fiber, and other lightweight materials go into the construction, but I still don’t see how these ships aren’t top heavy. When you read about warships, length, beam, draught, and weight all figure into seaworthiness. They don’t have to worry about armor plating, but these liners look like they would need 80 feet of draught.
Yeah, iit is an ungainly looking, top heavy-looking boat.
Not only tall, but with an a** that looks WIDER than the stern. Plus, it has gigantic swimming pools that look like they can slosh back/forth with a mind of their own.
On the other hand, I am certain a company (Norwegian Cruise Lines) that can drop $2 Billion on a boat can also afford to have the very best engineering and construction put in ti.
Nobody spends that kinda dough IF they weren't pretty sure that the first stiff breeze won't capsize it .. buoyancy mathematics are centuries old, and therefore well understood AFAIK.
We'd probably be amazed how this boat can manage it center of gravity depending on conditions (load, weather, seas, etc.). Plus, we don't see the hull shape and other physical features to help keep it upright.
we looked at this a while back in this thread.
What is the Bottom of a Ship Called & Look Like? (Every Part) - Cruise Ship Traveller
Heavy Metal
Anyway, I found this from Quora (for this boat in particular). That site doesn't appear to let one IP address to have repeated clicks, so I put an entire post [& relevant link IN that post] below.
Looks long but its an easy, five minute read.
"Having a low center of gravity makes its much more difficult for an object to be tipped over.
Although modern-day cruise ships look very top-heavy, most of the weight is distributed in the bottom of the ship and lower decks.
The hull is surrounded by a hull made of dense steel which holds the heavy mechanical machinery of the ship, including the engine room, air condition units, generators, as well food storage, luggage, and much more.
The upper half of the ship is much less dense, and much of the superstructure of the ship is made of aluminum which is lighter than the steel needed below for a strong hull.
One exception on the higher decks is the significant weight of water in the swimming pools, most often on the higher decks of a cruise ship, which raises the center of gravity higher up the ship.
These can however be emptied if required.
The center of gravity of a cruise ship can be controlled by increasing or decreasing the weight of the ship.
The Cruise captain and navigation crew have several options for adjusting the weight of the ship, including:
- Ballast tank water levels
- Fuel levels
- Onboard swimming pool levels
With the center of gravity pulling down from its original position and the center of buoyancy pulling up from its changed position with more of the ship beneath the water.
This creates a force which pushes the ship back to its upright position until the center of gravity and center of buoyancy are back in line.
The width of some cruise ships is nearly as wide as they are tall above the waterline. This also keeps the ship stable when being hit by strong winds from the side.
A Wide U-hull also helps reduce any rocking motions the passengers may feel and contributes to a more pleasant sailing experience.
Ballast Tanks
Ballast tanks are large tanks within the hull of the cruise ship.
They can be filled with water to increase the vessel’s weight and lower its center of gravity. The larger the cruise ship, the more ballast tanks they are likely to have.
Alternatively, if required, the water can be released and replaced with air to lighten the ship’s weight.
Ballast tanks are what submarines use to sink in the water. If they release the water, the tanks fill with air, and the submarine rises.
Bilge Keels
Bilge keels look like two fin-like structures running along the center of the cruise ship’s hull for about two-thirds of its length.
The purpose of bilge keels is to dampen the ship’s tendency to roll by adding resistance to the water as the ship rolls.
Summary: Cruise ships are designed to withstand the roughest of sea conditions. Although modern mega cruise ships look tall and top heavy, they have huge amounts of weight in the lower decks, making them almost impossible to keel over when facing even the roughest of seas."

We did these kinda boats a year or two back.
Container ships. these three boats -- ~1,300 feet long, ~60 feet wide, 20,000+ container capacity each, biggest engines (~80,000 HP) in the world, ~$150M each to build -- are currently the largest in service.
Ten minute vid. full of cool, nerdy facts if you want to get into that. That CMA CGM runs on liquified natural gas. Pretty remarkable.
You'll notice too, the USA is NOT in the building (or breaking at EOL) these behemoths. Asian shipyards are the builders, and India yards are the breakers (we did a few posts on the breakers).

Looks like a B-1 fuselage "on the move" somewhere? Must be a story here ... anybody know it?
Really!? Mounted like an "outboard?
Guess so .. i'm a land lubber. I'll be. Kinda like an R/B in a Neon?
Heavy Metal Oldie. Now this boat? I get it. Oh my. If you play vid, watch your device's volume level.

I've been on Royal Caribbean's Oasis of the Seas, the ship that's a little smaller. It was fun... They all are. The big ships seem to be aimed at families with kids. Water slides etc.
Royal is now looking at building some smaller ships for us older folks that don't need that nonsense.
While the smaller ship isn't the one we were on, it's a twin to it.
You'd have to work at it. Every railing is at least 4' high. The people that do go off intended to go into the water.

luv seeing these 80 year old fighters cranking up.
most all got mentioned in our WWII favs survey here a couple years back.
not sure i'd wanna fly in one but their owners/pilots swear by 'em.
the sound like their age at cold start .. then they go tear-a**in through the wild blue.
5 min vid.

It's a must do. I am partial to Navy ships, brings back a lot of youthful memories for me. I can walk into the main space of any conventional steam turbine driven power plant and name at least 90-95% of the equipment, how, and what it does in the loop. Most of that was learned long before I could legally drink a beer in the states.

This might be here, but under another of its 5-6 different names (Seawise Giant (1979–1991), Happy Giant (1991), Jahre Viking (1991–2004), Knock Nevis (2004–2009), Mont (2009–2010).
The largest ship, that could move under its own power, and biggest object the could move that humans ever built.
The Seawise Giant, its original name. Built 1979, scrapped 2010 (Alang yard in India, took 18,000 folks, working full time, a whole year).
1,500 ft long, 650,000 gross tons loaded, 225 ft. beam (width), 80 ft. draft (minimum water depth to operate), 50,000 horsepower.
Sixteen minute video, FULL of fascinating history on this boat. Well done piece if you have the time.
