Steam Tug
This is the "William C. Daldy". While she's a New Zealand vessel she was built in Glasgow in 1935 and is fairly representative of a vessel built right across Europe at that time. She's a proper steam vessel so she can actually do her rated 13 knots (24km/ph) and has a crew of ten. I've fixed up the plans a bit for clarity for you.
My only problem with her is that she's a harbour tug and thus has a deeper draught than a river tug. She's actually too deep for the upper Vistula as rated in the scenario which is given as 4.0 metres. Maybe she lurks downriver and you have to take her.
Here's her stats.
