We were renting a RIB Maestral 555 for last couple of years from this company, usually in pre-season and in post-season weekends. Experience with them is pleasant: always on time wherever we agreed for take over, boat is clean, technically in perfect condition and paperwork done. We visited all the islands around, Vis and Biševo as well, because 20+ knots of speed allow us to be there in a hour or two.
Antonio, guy I met, is extremely helping, always on line, patient and reliable.
So, according my multi experience, I can highly recommend Adriatica Charter.
