While the latest monthly satisfaction data shows train commuters are even unhappier - about everything - following the Queensland Rail driver shortage debacle, ferry users are practically euphoric.

Ask a ferry commuter how they feel about safety and security and they would probably give it a score of 90 out of 100.

Ask a train commuter and they would say 74, while a bus user would give it an 80.

The results are detailed in the November TransLink customer satisfaction monthly snapshot, which came a month after QR was "derailed" following the opening of the Redcliffe Peninsula Line, and more than 100 services cancelled on October 21.

Train commuters scored every category lower in November compared with October, but ferry users remained blissfully unaware of the chaos - even feeling happier about most aspects of their trip.

What about staff? Those happy CityCat people would give them a 90, compared with 77 for train commuters and 80 for bus users.

Satisfaction levels of 75 and above are classified as "best practice", while 60 and above is considered "satisfactory".

Reliability and frequency had a score of 78, compared with 63 for train users and 66 for bus users.

Comfort scored at 79 compared with 65 for train and 75 for bus users.

Efficiency, as in door-to-door travel time and avoidance of congestion, even scored at 78, despite the fact that most CityCat journeys would take longer than catching a train (68) or bus (70).

The lowest score from ferry fans was dished out to "affordability" but it was still markedly higher at 59, than train (45) and on par with bus (60) users.

Griffith University public transport expert Associate Professor Matthew Burke said there were several benefits of catching a CityCat as opposed to other transport options.

"People can actually work on the ferries better than they can on buses," Dr Burke said.

"We see a lot of people sitting with laptops, with papers, actually doing productive work, we see very little of this on the buses."

Dr Burke said catching a CityCat was also a "really pleasant experience".

"To be down on the water, to come in, arrive under the Story Bridge and have that visual experience," he said.

"It's also nice to be close to nature and water is one of those things that's been proven over time to make people happy."

Dr Burke said he had recently conducted research into go card trips during peak hour, where identifying information had been stripped, from Bretts Wharf to the city - where there was the option to either catch a bus or CityCat, with the stops next to each other.

He said a large number of passengers chose the CityCat, despite the longer travel time.

The bus trip would take about 23 minutes, whereas the CityCat journey would take about 40 minutes.

"We actually have people who are willing to travel longer because they get these other benefits," Dr Burke said.

"This tells us that some of the ways we do cost-benefit projects for transport projects probably needs to change."

Dr Burke said Brisbane's CityCats also had outstanding on-time running.

"It happens because there's never a car broken down in front of them, the river is wide, they don't have congestion problems," he said.

"They're extremely reliable. The other thing, and this is less remarked on, is there's only a small number of drivers and crew and regular passengers tend to get to know them, at least recognise them, so it becomes a pretty friendly service."
