The CTC ferry operates between Chebeague Island and Cousins Island.  Ours is a passenger ferry (no vehicles); no reservations required.  Cousins Island is connected to mainland Yarmouth, Maine by a bridge.  The ferry boat remains tied up at the Stone Wharf on Chebeague Island between trips.  So, when it's time for a trip, the boat leaves Chebeague with mainland-bound passengers, goes to Cousins, unloads and loads passengers, returns to Chebeague.  Each one-way trip takes about 15 minutes; longer if there is a lot of luggage, groceries, etc. to be loaded.
