Whether you are a bride, a school teacher, or a tour director, Casco Bay Lines is the way for your group to go! For transportation to an island or a specialty cruise around Casco Bay, you have a choice: you can go by our regularly scheduled service, or charter one of our boats for your own private ride.

Special Events

Celebrations and events are always more fun on a boat! Our private charters can accommodate groups up to 250 for a cruise around the bay or transportation to an island, with plenty of room for food and entertainment on the way.

Group Tours

If you are planning a group tour for 20 or more people going on our regularly scheduled service, please contact us to book your group. Although we do not accept reservations and cannot guarantee you passage, by booking your group we can avoid overcrowding the boat and ensure that we have enough crew members on board.

Island Lobster Bakes

For a real Down East experience, schedule a special group cruise on Casco Bay that includes a classic Maine lobster bake on Peaks Island.


A wedding on Casco Bay is guaranteed to be an unforgettable experience for you and your guests as you cruise among the islands, lighthouses and island cottages. Whether you are looking for a venue for a wedding ceremony and reception, rehearsal dinner, bachelorette/bachelor party, or just a boat ride for guests; Casco Bay Lines is the place.
