The Sodor Bay Tugboat is a tugboat that works at the docks. It is one of the few boats sold in the Wooden Railway line.
- 1993 (black smokestack)
- 1994 (red smokestack)
- 1996 (plastic stub)
- There is a stub sticking out on the stern of the boat, much like the stub sticking out on the bow of the Sodor Bay Cargo Ship. It was meant for a rubber band or piece of string to connect the tugboat and the cargo ship.
- It was also sold in the Percy Takes the Plunge Set and the A Day At The Works Set; in the latter, it remained active until the set got discontinued in 2008.
- The Sodor Bay Tug Boat prototype was listed as "Sodor Bay Tug" and featured a cab set further back, no text or life preserver prints on the hull, and slightly smaller cab graphics.
