Ship Building & Design, Anyone?

Posted: 06 Mar 2011 08:43 PM PST

I was looking at the biggest ships in the world and stumbled upon RMS Queen Mary 2, MS Oasis of the Seas and many other ships. Ship building is one heck of field - interesting and awesome. I've no clue about what kind of engines go into these ships and how they operate.

Can anyone here build a good discussion on ship building and design? It would be really interesting!
