This is probably my favourite 3D printed boat. Files are from Thingiverse and by "Tinkerman".As the inside of the hull is very shallow, I was unable to install a conventional drive. After much deliberation I decided to use a bow thruster. I purchased the smallest I could get (12mm) and hung it underneath, it works really well.
The original barge nowadays acts as a tourist attraction and has been somewhat adapted to be used to show people around the canals, the old city of Coevorden and former peat grounds of the Northern provinces of The Netherlands. Originally it was an almost empty hull (see original pictures) that was filled up with cargo, mostly peat, and that had some benches to transport people as well. Extract from Tinkermans write up. See photo's of original.
