Since my job change from seafaring to more shore based, I happen to work on Damen 2810 ASD tugs, in fact the boats I actually work on were "born" with the Smit Logo on the funnel base.
You are missing a few conspicuous details on the aft deck: 2810 has chests on the aft deck, on port side containing the fuel bunker station, on starboard the lb oil filling, and slops discharge connections, and the transom contains two equipment boxes.
The hull fendering goes all the way around, and the rear rope guide is in reality a LOT more massive: Where your print shows a flared out piece of sheetmaterial where the rope goes through, the real thing is massively filled out on the outside made out of heavy duty tubing instead of flared sheetmetal (apologies if those descriptions are limping a bit, English is not my native language, and tugboats never were my field of expertise so I am less fluent in the jargon of tugboats than that of the seagoing tankers I spent 31 years on).
I had a pic of the ex Smit Hudson, with the rear rope guide and PS bunkerstation visible, but I seem somehow not able to upload it, sorry about that.
In 10 days I'll be on board of another 2810 again and able to take some pics. I'll try and post them if I have figured out how by then
