A look aft from the starboard bow. A long slim steam  merchantman with several hatches to the cargo hold. Perhaps shen was carrying corn or something that shouldn’t get wet. Just look how well the hatches are sealed.

Name: Bounty (alternate)

Type: Merchantman

Affiliation: UFP

Captain: James T. Kirk

Year: 2293

Background: Freighter that operates in Federation Space. 5 man-crew are all former Starfleet including his Chief Engineer, Montgomery Scott. When Kirk found time-displaced Mia Colt at the Smithsonian Museum in San Francisco and heard her tale he knew he had to take her back to Algol, now deep in Klingon Space. It didn’t take much convincing to get his crew to do the right thing and they sped towards Algol. The engines however couldn’t take the high warp strain and left them stranded just on the other side of Klingon space, where they were used as target practice by the Klingons. A timely rescue by the Enterprise drove the Klingons away. The crew and passenger were beamed off and the ship presumably left adrift. 

So, a common criticism of sci-fi/space opera settings is that they have massive dreadnoughts and tiny freighters, but there are plenty of examples in space fiction of merchant ships being bigger than any warship, they just usually are a background element, not the focus of a story.
