This is my entry in the reddit competition to design a 100Dton Scout ship – any design rules. I went with the GURPS Spaceships ruleset which is an abstract design system that divides a ship up into twenty slots and various systems are then plugged in – fuel, engines, crew accommodations and so forth. Ships are rated by size, ranging from Size Modifier +5 (30 tons) to +15 (3 million tons). Exactly what a particular system plugged into a slot gives you depends totally on the size of the vessel. For example, a bridge on a SM+5 ship has one control station, while on a SM+15 ship it has sixty.
I went for a Solomani Survey Scout. This vessel is designed for survey and research work. It has enhanced scientific sensors to aid in this work. It carries eight crew in somewhat cramped conditions, which is normal on Solomani ships compared to Imperial vessels which allocate more space per crewman on average.
