In Maine, the only regulated ferries fall within the Casco Bay Island Transit District. The PUC regulates these ferries in order to maintain affordability and the continued existence of the island communities located in Cumberland County and Peaks Island, Great Diamond Island, Little Diamond Island, Long Island, Chebeague Island or Cliff Island, or between the islands mentioned.
