It provides riverine express transportation between stops in the capital city of Bangkok and to Nonthaburi, the province immediately to the north.

Established in 1971, the Chao Phraya Express Boat Company serves both local commuters and tourists.

[1] Along with BTS Skytrain and Bangkok MRT, using the boats allows commuters to avoid traffic jams during the peak hours on weekdays.

The engine room, in the appearance of a large wooden box, is inboard in the center line of the boat in front of the seating area.

This design has been applied to all other boats that are being built in the company's shipyards in Bangkok and Ayutthaya.

The engine rooms are placed lower than those in single-screw boats, and some passengers prefer to sit on them when it is crowded.
