You can fly the PBN Nomad, which is pretty much the Catalina / is the catalina, but it's a sea plane with no undercarrige, not an amphibian, ie the nomad can't land on the ground , whereas the Catalina has an under carrige for landing on the ground as well.

get the Unified Installer if you haven't got any mods yet, or if you have, look for the PBN Nomad.
