Bulk Carrier Cargo Ship

This is a little Modell of a Bulk Carrier. It can swim emty. If you want to put some Cargo inside you have to add some weights at the bottom of the ship. I used 5* 5 cent coins. I painted it with Acryl colour.
I think it is possible to ad an engine to move it Rc.
The ship can load about 40cm³ of sand. It weights empty about 110 gramm. I just glued the bridge and the front deck to get the sand out of the cargo holes.
It is no certain ship. I had some pictures and the size I want to have it.
The pictures shows the prototype. The files are improved versions. Now the cargo holes are in the middle and there aro no big gaps.

In my garden Is a little fountain where I let it swim. So I will also make some other ships.
The ship have no certain scale but the doors are 2,5mm high.
