I have a couple of videos taken of the Dubai Ferry at the Marina Mall Water Transport Station. To get there you can go through Marina Mall and then turn left – once you get round a corner (only a short walk) you will see the place where the ferry docks (as well as the water taxi).
This video just shows the Dubai Ferry docked with the passengers arriving and embarking on the 5pm trip:

The next video shows the ferry setting off from Dubai Marina for the trip around the Palm Island:
The RTA have produced a promotional video about Dubai showing the new boats that are being used the for the routes – the Dubai Ferry is very modern and slick as you can see from this video.
The commentary for the video is in Arabic but the pictures give you a good idea of what it is like.
Here is another video of a misty day on Dubai Ferry:
