This 1-20* scale tug is my interpretation of the 1950/60’s drawing by Vic Smeed from Model Maker magazine. (*Since it’s not based on an actual boat, the scale is estimated.) It was called the “Keenoma,” and the shape was inspired by a real Canadian tug. I have added several details, but the modeler will be able to add as much detail as desired to this simple design.

I tried to keep all pieces under 250mm for printing. Some slicing may be required though.

At 1/20 scale, this model is about 1.2m long, 255mm wide, and 484mm tall with 43 files +instructions. (Some are printed in duplicate.) As always, let me know if you find anything that can be improved and I'll get the updates out.
