YTB-142 “Nokomis” Tugboat

The Nokomis is a Woban class district tug.  The original tug was 100’ long but the model is just 8.3 inches long and 3.9 oz total weight in 144:1 scale.  The tug was made from a homemade fiberglass hull and includes rudder control, a brushless motor, and a 300 mAh LiPo battery.  It performs well, able to (slowly) pull an 11 pound ship model and turn itself within two ship lengths.

The superstructure becomes a recovery float in case it sinks, with a small winch hidden inside to spool the recovery line on. A single super magnet holds the deck on.

Towing my Roanoke.  It didn’t tow fast and it was hard to turn, but it did work
