The Hammerfin class transport/light freighter was one of several first attempts by Naxos Yards at civilian vessels. Naxos Yards had long been known for its excellent military vessels built exclusively for the Royal House of Naxia. But as government contracts were filled, the company needed some means of income. Naturally, that meant building civilian vessels for Naxos and the other worlds of the Royal Sector. Most of the other first attempts were simple, boxy, and utilitarian cargo vessels. These did not sell well; the reason was that there were already several ship building companies in Known Space that were well practiced at building excellent utilitarian cargo vessels. So, Naxos Yards pursued the more successful avenue of "ships for the common man". There were many wealthy individuals, and noble houses, that could easily afford a personal yacht, or even a fleet of personal yachts. However, Naxos Yards designers were still thinking in the form of cargo transportation at the time they designed the Hammerfin. This class of ship turned out to be mildly successful as it allowed small business owners to afford a cargo vessel to haul their goods and equipment. One growing small business, called Green Space LLC, which focused on floral arrangements, decorative plants for the home, and hobby gardening, was in the process of expanding and purchased five Hammerfin ships for their business. Another small business, Gryphon Couriers LLC, also purchased several of the vessels, and then requested some rather unique modifications that mostly focused around increased armament -- apparently the courier vessels delivered v.i.p. cargo and people through rather dangerous areas of space, and extra weaponry was needed to ensure their safety.
