Dethboat

The Dethboat is a river boat used by Dethklok in their journey to the amazon in Metalocalypse episode "Dethcarraldo". The boat was too huge to travel to the amazon through natural water passages. The Klokateers had to destroy a portion of the rain-forest so the Dethboat could be dropped down from the air only for it to land in a different part of the river after the fact.

It appears to be fueled by nuclear energy based on the green glow that comes from its rear. It also is adorned with viking shields on it's port and starboard sides. There is one large smoke stack in the center and four adjacent cannons raised at 45 degree angles, two pointing off the port and two off the starboard side.
