I have some rust in my mouse...
Here is the MV Deo Volente and her sister unit MV Eendracth: these ships are used to carry also "medium" stuff at a cruise speed of 18 knots. Most of the pictures are showing windmill bases, large cable spools and other industyrial stuff not so fine: I figured a "fast transportation of an hystorical ship like the steam tug Pietro Micca made by MV Eendracth. In a more realistic drawing she could transports a Damen PB.
