Hi Mikael. The ferry from Venice only goes to Mali Losinj on Fridays and Saturdays. So you would need to go on July 17th, 18th, 24th or 25th. Check it out at http://www.venezialines.com/eng/index.asp or http://directferries.co.uk/. If you use the direct ferries site, you have to select Euros as the currency in order to see the Venice-Mali Losinj schedule.
