Yes, there are several "fast ferry" (catamaran) services connecting Dubrovnik and Split, which are among the most popular ways to travel the Dalmatian Coast in 2026. The primary operators are Krilo (Kapetan Luka) and Jadrolinija. These high-speed vessels take approximately 4.5 to 6 hours to complete the journey, depending on the number of island stops. Most routes are not "direct" but instead act as a scenic "island-hopping" shuttle, stopping at iconic locations like Mljet, Korčula, Hvar, and Brač (Milna/Bol) along the way. This makes the ferry a much more pleasant alternative to the 3.5-hour bus ride, as you can enjoy the Adriatic views, a snack bar, and comfortable indoor seating. However, these ferries are seasonal, with multiple daily departures from May to October and very limited service in the winter. It is highly recommended to book tickets online at least 48 hours in advance during the peak summer months, as these catamarans frequently sell out. Also, be aware that these "fast" boats are sensitive to high winds and rough seas; if the "Jugo" or "Bura" winds are strong, the service may be cancelled, and you would need to switch to the coastal bus as a backup.
