The Carrack class of transporters are a class of small trading vessels, designed and built for the new captains of the Trading Guild to transport goods over medium length hops. She is also the first class of trading vessels mounted with steam turbines rather than the old fashioned coal engines, which were mounted to Iron Clad warships and conveted sailing ships. However the trading guild failed to warn new captains to stay whithin the safe confines of their central empire, and not to travel out into the rural islands as steam turbines were still a new technology and were prone to the odd breakdown.
Whithin the first few months of the transporters release, one was captured after a lengthy fight and was taken back to the Deep Ocean Orders R&D, where they stripped it down and learned how to build steam turbines. This mistake of forgetting to tell new captains to stay whithin the safe confines would later come back to haunt the Trading Guild, as the Deep Ocean Order began a massive refitting project.
