The Moby Dick is one of the better-known boats on the tour circuit in and around Berlin. The dh and I gave it a whirl awhile back when we did a tour of the lakes and canals just north of the city. It was a relaxing afternoon/early evening and now I can say I've finally been on the famous Moby Dick! If you want to see the view form the inside of the boat, take a look here.
