None of the friendships, launches, and ferry boats are on tracks. All other boats i.e. the jungle cruise, dark rides, etc. are on tracks. The "tracks" are a walled barrier just under the water that doesn't let the boat past. These tracks are usualy not visible unless you are looking for them, You will be able to feel the boat hit them and adjust course however when making a turn if the are present.
Any water way where boats have the ability to free roam or is an open area where other boats may cross can not and do not have any "tracks."
The boats on the the seven seas lagoon, the lake at Epcot the water way from epcot to MGM, and the water way to and at Downtown Disney have no tracks of any kind.
