OK, some mind work today, and here are some ship classes that can be found in Pulsar:
Clipper - surprise, ins't it?
Resourcer - another surprise?
Barque - trader in other words. Slow, large cargohold, slow, but quite well shielded and armored
Starscream - fast, high manoureability, small cargohold, but can use cloak and has a build in scaner
Battlecruiser - any description needed?
Cruiser - universal platform
Dreadnaught - so u wanna raid smth?
Explorer - super fast, high scanning, high cloak, weak weapons and defenses, but small size and high manu makes it hard to hit
Destroyer - pure fire power. But low speed make is rather a special ship
