From publisher blurb:
The Percheron-Class Heavy Trader is a versatile, older-model cargo vessel intended for independent bulk mercantile operations. Originally designed for use by Belters as an ore carrier and processor, it came into its own as a vehicle for autonomous trading operations. Some ship owners have taken advantage of the ship’s versatility to convert their Percherons to passenger liners, a light prison transport, and a scientific survey vessel. But the majority of captains find that its usual role as a small bulk carrier puts credits in their pocket.
Shipyard: Percheron-Class Heavy Trader is intended for 2D6 games such as Cepheus Engine and the Original Science-Fiction Roleplaying Game (OSFRPG), although it could be used in any science-fiction milieu with a few modifications.
