You can see this a little better if you enlarge it -- it is near the stairway down where there are more benches to sit on.
Don't you just love these benches? Life vests for children and adults are stored under the benches. . . 
There are two levels to ride on the ferry inside. I was trying not to take photos where people were sitting so just got a few examples of the long benches to sit on indoors on the ferry between Port Orchard and Bremerton.
