I'd never sullied a pair of deck shoes by actually treading on a deck before, so this wasn't a great start to a week's learning-to-sail break. But Croatia is made for sailing, late-season storms aside. From Dubrovnik past Split, more than 1,000 islands stretch along an Italianate coastline where Venetian rule has left an imprint on every white-walled, rose-tiled town, there's no tide to complicate things and the weather is actually damn fine for most of the year.
