I've wanted to know just how long it takes the aquabus in Fontaine to get from point A to point B, and whether or not just running or sprinting on the sides of the aquabus route is quicker than taking the aquabus directly. Well to answer this, I did a test and measured the estimated time it takes for each category.
Some few things of note before I reveal the measured times:
Testing was done on the Clementine Line from Romaritime Harbor to the Court of Fontaine because it is the longest of the aquabus routes as of current.
I used medium-sized characters because they are the mean average when it comes to movement speed.
I had Anemo Resonance active when doing these tests because I wanted to compare the fastest run and sprint times of the medium characters to the aquabus.
There will be a small margin for error for these measured times.
Here are my results:
Aquabus: 5:53
Normal Run: 7:25
Normal Sprint: 6:21
Alternate Sprint (Mona and Ayaka): 5:04
Yelan/Sayu Skill Combo: 4:26
Surprisingly, the aquabus is a lot faster than I give it credit for. It can outpace the normal run and sprint speeds of most characters, with only the alternate sprints of Mona/Ayaka and the Yelan/Sayu Skill combo being able to outclass it.
