+1 for carrying a bungee or two. Some miscellaneous fabric (for wedging between the frame and the contact point on the ferry) wouldn't hurt, either. And when your bike gets scratched while on tour, do what I do and cover the scratch with a decal from the place you just visited. My entire frame is now plastered with "mementos" from cool places, and I get to look at them for hours at a time when I am riding.
