Purchase preparation
Before buying on an island, read the winter sailing schedule
Whoever meets an island in July has met its best version. Before deciding to buy, open the November timetable: the number of winter departures shows how connected a place is when there is no season.

Why the winter timetable is the honest one
Jadrolinija publishes sailing schedules by period, and on smaller lines the difference between summer and winter can be the difference between five departures a day and one.1
Coastal liner traffic in Croatia is organised as a public service, so inhabited islands keep a connection all year, but the density of that connection drops in winter.2
What to check in the schedule
The first and last departure define the day: an early first boat means you can reach work or a doctor and return the same day, a late last one means an evening in town does not end with an overnight stay.1
Also look at duration: some lines run slower in winter or add a stop, so the same route takes noticeably longer than in summer.1
How this shapes everyday life
The state network of coastal lines splits into ferries, ships and fast boats: a ferry carries a car, a fast boat only passengers, and exactly this difference decides whether the island needs a second vehicle.2
