The Arvad is the multi-generational ship on which the pioneers arrived in Adalia. Built to house thousands, the Arvad travelled for 150 years from Earth to reach Adalia at an average of roughly 10% the speed of light. The passenger living spaces are spun at between 2 and 3 RPM to achieve artificial gravity of 0.5g, which matched the gravity at the Arvad's original destination. The Arvad is the only non-playable ship in Influence.
The light transport was the first ship to be built from the partially disassembled pieces of the Arvad. Although it's cargo capacity is fairly small, it's capable of travelling between asteroids at relatively high speed, and is capable of hauling enough goods and resources to bootstrap settlement of newly acquired asteroids.
The heavy transport is much slower than the light transport, but can carry substantially larger payloads. Developed shortly after the first prospectors began mining, the heavy transport is also built from the remnants of the Arvad, and is best suited to hauling large quantities of raw materials and refined ore.
The shuttle is built solely for the transport of human passengers around the belt. A tiny ship, effectively just a command module strapped on top of an engine, the shuttle can sustain 9.8 m/s acceleration for the entire acceleration and deceleration phases. This has the dual effects of maintaining 1 Earth gravity throughout the entire trip, and facilitating rapid travel around Adalia.
A surprisingly philosophical way to travel. Just you, some breathable air, and the stars all around you. You can go anywhere, but you can’t bring much of anything with you on the voyage. Or maybe that’s just the first symptom of encroaching space madness.
