As a followup to “Mystery Tugs,” here’s a few more. My favorite, below, could be called the naked tug: controls under an awning, slant mount engine, a welding unit, and the hook. Last chance to guess the location and river: a clue is that its name means “river of kings” and previously locals referred to it as Menam.


A passenger vessel cuts close to a tug with an unlikely portside door, and what hangs over the engine compartment?


Laundry and more laundry.


So, all these tugs operate on the Chao Phraya, flowing through Bangkok, where Richard lives and  Conrad set such works as Typhoon, Secret Sharer, and Falk, a novella about a tugboat captain.
