Both, the Powering Down images were test renders to see how things looked. I had an older PC that sometimes could not manage. the later ones are with the drydock and Jefferies SpaceTUG. I will get around to posting my "Reimagined Enterprise and fleet"
IMO a TOS era tug should be named for someone from that era, not from the TNG era. Like a Jim Rugg "Rugg Tug"
yes good idea, originally I named it for Gary Hutzel as he had just recently passed away when I made it. but Rugg Tug sounds damn good I later named one of my reimagined Starships after him too.
