I heard years ago that they were working on the concept of trimaran designs for ships, but I missed that they'd actually launched one!
It does seem to have a little bit of a Star Destroyer look to it. Maybe we should keep an eye on Senator Byrd, just in case ( he looks a lot like Senator Palpatine in eps 2 and 3, meant as a joke and not any kind of political commentary ).
Another real-life sea vessel it reminds me of ( and, I'd say, could be considered a kind of ancestor or something ) if you ignore the extension of the bow is the Sea Shadow.
