The Ferengi operate many small trading ships, the Grok Light Trader being one of them. A medium ship, the Grok is large enough to haul bulk cargo for long distances. Groks are easy prey for raiders, as their light weapons are inadequate for taking down enemy ships before the Grok's shields are depleted.

Grok Light Traders are most often run by Ferengi who are "second sons" and, thus, did not inherit the family fortune. They are forced to run low class, drudging cargo missions in order to earn the profit they so desire. Some more affluent operators also use Groks for minor cargo routes or errands, but never would they themselves travel aboard such a craft.
