Two companies, BUDO (Bursa Deniz Otobüsleri) and İDO (İstanbul Deniz Otobüsleri) operate fast catamaran passenger ferries across the Sea of Marmara between Istanbul's Kabataş docks and Bursa (map) in about 2 hours. Both are municipal companies owned by their respective city governments.
Each offers between 4 and 8 voyages daily in each direction, depending on the day of the week (Saturday has fewest) and season of the year.
There are snack bars serving snacks,
sandwiches, hot beverages and soft
drinks on board the vessels.
