I don't have Koal's USS Consitutaion, but I do have the Golden Hind.  His ships are beautiful, but resource hogs!  They also import with lots and lots of extra stuff that you may or may not want in your scene.  For example, both the furrled and full sails are on the ship when I imported it.   It has details right down to water buckets.  On my crappy work computer with only 1 GB of memory I can import the ship with everything.  My resources drop from 79% to about 52%.  Purging memory doesn't really get me any more resources back - this model is just plain BIG at 571,034 polygons!  I converted it to vob, but the resources still remain the same at about 56% to 62%...

Vue is not acting unreasonable for such a huge model.  Adding another large ship without getting rid of some of extra stuff may not be possible.
