This afternoon, the inland barge SAKURA was seen passing through the Evergem lock (Belgium) at http://webcam-binnenvaart.nl/. I've taken a few screenshots to compare with Nautis Home.
SAKURA is a dortmunder ship : 73m long, 8.20m wide, 1052t high tonnage. This boat loaded in Rotterdam (Netherlands) for Valenciennes (France), on the river Escaut.
To take the screenshots in the game I used the HERMELIN, a kempenaar ship (55.40m x 6.70m) the same day at the same time.
