Hm..well both are great. You have one way cruise now going from Split to Dubrovnik or Dubrovnik to Split. Or you can try the Southern explorer (KL_2) which I hear is one of the best, where you get to see great places and islands such as Korcula, Mljet and Hvar. over 6 years agoAnswered by Antonia2110 via Travellr.com
Well, depends on what you want...
Split area has larger islands with a larger tourist offer, and are generally the most popular for sailing in Croatia.
Dubrovnik area, on the other hand offers a more exotic feeling of sailing and smaller, but equally beautiful islands.
Here's a description of sailing destinations in Croatia, maybe it helps more http://chartercroatia.net/sailing-destinations/ over 3 years agoAnswered by DaV1002 via WorldNomads.com
