Time Out says
Based at the marina that dominates the main seafront at Funtana, Istra Nautika has all kinds of boats for rental, with or without a skipper. Vessels run from a basic Reful and its 30-litre tank to a six-metre Barracuda SX, with a sundeck and shower cabin, which can accommodate up to seven people. A skipper is generally a good idea as he can point out landmarks such as Cape Grget, the uninhabited islet of Veli Školj and the other smaller outcrops that dot this part of the Adriatic. You may also wish to plot up a less crowded beach, either towards Vrsar or Zelena in the opposite direction.
