Tim and I enjoyed a great ferry trip from Whittier to Juneau last month. If you are interested in seeing our adventure check out this site. I had a SPOT GPS with me and checked in at various waypoints. After we got home I uploaded some pictures to go along with the waypoints. I learned a lot by doing this and realize I made many mistakes in putting it together but it was a good exercise.
Note: I used a co-workers account so when you go here you'll see her picture, not mine!
