We are a party of 4- 6 people that would like a private manned sailing, yacht, or catamaran charter for 4-7 days from Split to Dubrovnik. Late May-Early June 2019.
I recommend Zizoo. Booked with them for a week this Sept. Responsive and resasonable price
Sorry that I don't have any direct experience to offer you, but we are also considering a crewed catamaran during the same time period. I would love to know what your research has turned up, and I'll be happy to share anything that I find. Thanks
