Romanian high-power tug ZIMBRUL class

Hello guys!
I haven't write on the forum for awile, just watch your discussions, very interesting subjects, i just hope you will watch this thread too.
After a long period of documentation, (about 3 years) i have started the build of this tug about two months ago. It is one of the most powerfull tugs that operates in Black Sea, with twin diesels of 3300HP each.It was designed in 1986 at ICEPRONAV, the romanian ship design institute. There are four ships in this class, three in romanian navy and one in Greek service.
Some specs:
Lenght-35.80m
Beam-11.8 m
Twin props with a 3.8m in diameter in nozzels.
Can be used also as a icebreaker.
I am having almost the complet sets of shipyard drawings for every part of it, about 124 sheets of plans!

I hope you will like it
Best regards
George

The model is in 1:45 scale, with a total lenght of 81.5cm.
i have used two Pro480 motors with two belt gears obtained from old Canon Ink-jet printers with small modifications.The gears ratio is 1:8, so at 6volts the props will have about 1200rpm/min at max. I will use two scratch built props, from brass with a 78mm in diam. The full size props are having variable pitch and my wish is to have this on the model also...
Some pictures...

I was on the real ship this summer at Constanta port and take about 300 pictures.
The nozzles are molded from fiberglass with styrene rudders.

That's great work. I like the finish of the hull. I've always liked the flat look better than gloss.

Cheers,

What a monster! if the scale is anything like the full size version you could use it to tow you in a dingy and go trolling!

Back with some pictures.
First thank you for watching this, and Umi i know you are a really specialist in modern ships so i will really need some help from you and other guys here during the build because this is my first "modern" tug. .
I have used email colours for airbrush, then covered with flat clear.
The model is having independent propulsion for each prop and also independent move for the nozzles. I can also mix them from the remote.
From my calculations it will have about 10.9Kg ; and lots of power i hope

As i have write before i was on the tug this summer and had the chance for a small run (about 4 Hours), during this time it towed a very large cargo(new build) out of port for first sea trials and belive me it it a very maneouvrable tug even without bowthruster. The bollard pull is 107tons wich is quite impressive.

Last week i have also begun the build of the superstructure, simple as form but very complex in details, alot of angles especially at the funnels.
I have used 0.8mm thick plywood for the walls and 2mm ply for superstructure's frames.

Hello guys!
I have made some progress, not much because of the time. I have used styrene to make the pieces like vents and some welding lines on the superstructure. Have also prepared the place where the towing hook will rotate; also used styrene for this and a rail from my collection of modeltrains.
