Last year Clyde Clippers launched a river bus operating five days a week from the city centre to Braehead.
It proved so popular that this year the service will run seven days a week with a new stop at the transport museum, which opens on June 21.
The MV Rover, which began operating this week, can carry up to 80 passengers and will have pick up points at the Broomielaw, Glasgow Science Centre and Braehead.
Clyde Clippers is also the company behind the new Govan Ferry, which from June 21 will take visitors from Govan to the new museum.
Clydelink, which runs the Renfrew to Yoker ferry, has also launched a waterbus service between the city centre and Braehead.
It will also run from the Broomielaw seven days a week, stopping at the Science Centre.
There are plans for the service to stop at the Riverside Museum when it opens.
Clydelink's boss Mark Aikman said: "We believe there is strong demand for this service."
