   Thanks Doug, under the umbrella of not knowing much about electronics, I sourced a micro / nano 2 phase 4 wire stepper motor and a 5v driver complete with remote controller and reduced the 12v supply accordingly with a regulator. I then retrained to be a "micro surgeon" to wire it! Results are not as good as I had hoped as the lowest speed is jerkey and the lowest smooth speed is a little too fast but I'll live with it for now and put it down to experience. Maybe it could be smoother with a Arduino controller but I couldn't find any constructive advice at the time and wasn't prepared to invest the study time. I'm guessing electronics is your thing 🤔 At least I learned something!😌

   Brilliant, slick job Seafarer👍
   I especially like the illumination.
   Reminds me of what I've often seen on tugs in Hamburg.
   What are you using for radar drives?
   On my destroyer (some thirty years ago😉) I used a converted servo powered by a 1.5V alkaline cell. Switchable via a home made 4 function circuit board. Ran for yonks on one cell.
   Happy tugging. Cheers, Doug 😎
