The Bay of Naples is among Italy’s most rewarding sailing grounds, and Ischia gives access to it from the western end. The thermal breezes are predictable in summer, the passages short enough to allow unhurried mornings at anchor and afternoon arrivals at the next destination. Capri’s Faraglioni stacks make a natural waypoint on the southward leg, and the approach to Positano under sail, the village stacked against the cliff face ahead, is one of the Mediterranean’s finest arrivals.
