There is limited ferry service between the islands of Maui, Lanai, and Molokai. The Maui-Lanai ferry departs from Lahaina's waterfront five times daily to Manele, Lanai for about $30 each way.
The Maui-Molokai ferry departs twice daily from Lahaina, Maui and lands at Kaunakakai Harbor, Molokai with rates around $50 each way.
Please note that both ferries are for foot traffic only and cannot accommodate a car.
The Super Ferry was shut down as of March 2009. It is unsure as to when or if it will resume operations. The massive controversy was surrounding the unknown environmental impact on the coral reefs and sea life. Currently, there is no island-wide ferry service nor is there a ferry that will accommodate a vehicle.
Inter-island travel can be accomplished by private boat charter or an inter-island airline.
