A ship that is briefly described in the Star Trek Lost Era novel 'Serpents Among the Ruins' by David R. George III. It is thisdescription that guided my creation of this model;
"With a particularly wide beam and shallow depth, the starship looked as though it had been compacted top to bottom, and spread port and starboard. The primary hull, a narrow ellipse with its major axis running fore and aft, had no rise to it at its center. The secondary hull, another level, narrow ellipse, but smaller, connected to the primary hull directly, the forward section of the former lying directly below the aft section of the latter. A pair of thin struts, angling backward, connected each of the two warp nacelles to the secondary hull. The nacelles themselves were flat and wide, flaring out broadly from their midpoints aft. The two-hull, two-nacelle alignment suggested a resemblance to other Starfleet vessels, but departed dramatically from those other designs in execution."
