Back when I was in college, one of my aeronautical engineering professors showed us this journal article written by John McMasters, which was about very large transport aircraft that could be built with existing technology.
One of the more interesting designs he he talked about was for a 1,200 passenger tri-fuselage seaplane, the "Super Clipper"
The 2 mid-wing fuselages are as big as a 747, and it would be sea-based due to the size.
Pretty interesting designs, if anyone has access to journals, I believe this is the article -
McMasters, J.H. and Kroo, I.M., ”Advanced Configurations for Very Large Transport Airplanes”, Aircraft Design, Vol. 1, No. 4, 1998, pp. 217-42.
While I really like amphibous aircraft, I suspect that this airplane would have serious finacial problems. For one, how do you get 1200 passengers onto / off of such a plane without taking more time than the flight itself? I suspect boarding times of 2 hrs would be realistic. Consider the fact that people would get on, sit down, wait, wait some more, get up to go to the bathroom, get bored, check their luggage for something to entertain them...etc.
Maintainence would be another problem. Unless this plane is truly amphibious (it could roll up onto a tarmack instead of a dedicated seaplane that is always in the water) getting equipment out to the plane in order to maintain it would be difficult.
Also, what is the market for such a plane? It cannot land at inland airports, so many destinations are out of consideration.
I like unconventional designs, though. If the above questions could be answered I'd be all for it.
