It is with great honour and pride that I herby launch the largest transport ship to ever sail the worlds waters.- Chief Constructor at launch of the Leviathan
The Leviathan was built to serve one purpose only: transport as much as possible as cost effectively as possible. Therefor it was significantly larger then any contemporary transport vessel.
The technology that allowed the Leviathan to reach its significant size was the introduction of Carvel planking. This strengthens the hull beyond a certain size.
During its lifetime the Leviathan transported goods across the Stormsea. The goods that were in the cargo hold were usually very voluminous.
The one exception was its final journey, when it was supposed to have carried a load of wheat, but due to a conflict that broke out, the cargo was exchanged for mercenaries heading for Auwan. The ship was attacked by pirates and after much spilt blood, the pirate queen had the Leviathan sunk, as described in the story of A pirates greatest accivement, found in the book A travellers guide to Auwan.
