Master the Passage: Pula to Malta Offshore Adventure This is not a leisure cruise. Master the Passage is a serious, advanced-level offshore passage from Pula, Croatia to Valletta, Malta — approximately 700 NM down the Adriatic Sea and across the Ionian. Designed as a non-stop, immersive offshore masterclass, this passage will build your confidence and sea miles. You will retrace the historic Venetian trade routes, navigating the length of the Adriatic before making landfall at the legendary fortress city of Valletta, just in time for the Rolex Middle Sea Race.
