She is 50" long and 12" wide...single screw driven through a kort nozzle.   I owned her from 2004 until last year.
I built this tug from a bare hull using wood planking.  I installed twin motors in her and a steering mixer, basically that enabled her to turn in her own length whilst still, amazing to watch!
'Breeze' was based on a real tug 'Smit Nederland', was in a scale of 1:28 which made her 42" long and 10" wide.
The Infamous 'Breeze' !    ;)

She's a model of a Polish or German built 'short sea' trader, they're around European waters in their hundreds because of their small size its not unusual to find them one day fighting through a North Sea gale and the next parked up a little creek unloading....high and dry and miles from the nearest coast.
Note the name and port of registry  ;)

The real life tug was built in the mid 60's and along with another five almost identical boats worked for the Rea Towing fleet in Liverpool.  Hailed as a class of vessels that were the most powerful single screw tugs afloat at the time unless you read the 'small print' one wouldn't easily know that these boats had two diesels geared to one prop shaft...so they should have been strong!   I think they were a nice looking tug and it made a nice model too I made this model at the same time as the HOLMGARTH and she was sold to a customer in Swansea.

I started with a blank hull here, and she'll never take the prize for the prettiest tug afloat but she's certainly the strongest.  Those motors were taken from a JCB tractor cab and were used for the air conditioning.  Like I said not the prettiest, but another that I hardly got chance to use, she was seen on her 'sea trials' and sold there and then.  Couple of pictures of her during building and then on her 'trials'.  By the way, I am rather proud of that mast and she's not really THAT ugly once afloat!

This is the ship that got me hooked on model tugs, not the biggest in the world at about three feet long I just so enjoyed building and operating her.  When eventually sold it was to a banker from the US...this tug happily now lives a life of luxury on Central Park boating lake in NYC!
