Aha!
Your last comment sums it up! For whatever reason there's a plethora of "Titanics" When there are others that met igniminous ends too. Can you say Lusitania, or Brittanic ?
And for modern ones that come to mind the Andrea Doria and the Costa Concordia!They do now have a Paper model two ship set ! of the Andrea Doria and the Stockholm with detail sets too. I have a Tanker kit, paper, that looks a lot like the EXXON VALDEZ.
But there's much more. If you really want larger sizes you will have to look to wood. Either Plank on Frame or Plank on Bulkhead! Bluejacket and Sterling Models come to mind. Although I think Sterling may be defunct! I believe it's Bluejacket that has a nice Liberty.
