According to Chris Lloyd, he was disliked by the steam tugs, who feared the thought of a new diesel tug. In the first few episodes, the diesel tug only appeared as a hull frame, but as the episodes progressed, he became a red oxide hull, but still with no superstructure or head.
- The diesel tug was never a character as such; it seems likely that if TUGS had a second season, he would have been featured.
- The diesel tug was first acknowledged in an interview with TUGS model maker, Chris Lloyd on SiF. The interview can be found here: .
