This is the ferry from Dar es Salaam to Zanzibar. Actually, this is the fast ferry. There are others. It was comfortable except for the wiggle-worm behind me that kept poking his knee into my back. One thing I can say is that my Kindle had 5 bars of 3G reception all the way across the water during the trip. I have learned that I need to find some really good Kindle-formatted news sites for trips to places where regular internet service is sparse and 3G is available.
