If you are looking for a tug boat look no further than the Model Slipway "Wyeforce" harbour and berthing tug. (Scale at 1/24) I have made one for my wife and she is highly delighted and after a couple of times on the club waters wanted the one ESC upped to two so she could maneuver it better. there is plenty of scope for additional items such as lockers and oil drums on deck and heaters and notice boards in the wheelhouse
Check out my pix’s in the galley,just been entered in our clubs Yearly build comp,no results yet!
http://www.modelslipway.com do other tugs as well but can’t comment on those as I’ve not built them although a chap in our club as built the Naval tug and it looks very good in fact one of the contenders in the kit comp with me
