Montague is a trampsteamer. Like Izzy Gomez, he tries to get into port for free but only travels at night. His face is a bit shady and un shaven. He transports illegal goods to and from the port but only through the night. He only moves at a slow speed until he's out at see and rides along side moored tramp steamers so to be camoflaged with surroundings.
During night, other ships go by to try to find out where the sound of the ship is coming from but never seem to find him. He's is no where to be seen during the day.
