An island is defined by its boat and by its winter timetable
Everything about visiting an island — cost, availability, risk and atmosphere — is downstream of how often something crosses the water and what happens when it cannot.

The boat is the infrastructure
On the mainland, transport is one service among many. On an island it is the precondition for all the others: food, fuel, post, building materials, medical transfer and the workforce all arrive on the same vessel that brings visitors, and when it does not sail, none of them arrive either.
This gives the timetable a weight it does not have elsewhere. It is not a convenience to be optimised around but the structure of the week, and islanders organise appointments, deliveries and travel around sailings in the way that people elsewhere organise around working hours.
The size of the boat matters as much as the frequency. A vessel that carries lorries can supply an island properly; one that carries only foot passengers means everything heavy comes by a separate and less frequent service, which shows up in what things cost in the shop.
Summer and winter are two different networks
Almost every island route runs a seasonal timetable, and the difference between the two is not a matter of degree. A crossing with several sailings a day in August can drop to a few a week in January, and some routes stop entirely, leaving a longer or less convenient alternative as the only link.
Fast craft are usually the first to go. Light high-speed vessels are more weather-sensitive and more expensive to run, so they are commonly withdrawn for the winter while a slower conventional ship maintains the service. That changes journey times substantially on some routes.
The timetable change also affects connections beyond the island. A winter sailing that arrives in the evening may no longer meet the last bus or train from the port, which turns a straightforward journey into an overnight stop that nobody planned for.
Weather cancels boats, and it cancels them at short notice
A ferry is cancelled on the basis of wind and sea state at the port and along the route, and the decision is often taken only a few hours ahead. Two islands the same distance apart can have completely different reliability records depending on the shelter of their harbours and the direction of the prevailing wind.
When a sailing is cancelled the backlog does not clear instantly. Vehicles and freight that missed one crossing compete for space on the next, and after a run of bad weather it can take several days for a route to catch up, which is exactly when everyone else is also trying to leave.
Where a route is designated as a lifeline service, the operator is under an obligation to maintain the link and will sail in conditions a commercial operator might not. That improves reliability and does not remove the problem, because the sea still gets the final say.
Everything on an island arrived by boat
Freight cost is embedded in every price on an island, which is why a bottle of water and a bag of cement both cost more than on the mainland and why the gap widens the further out and the smaller the island is.
Some resources cannot be shipped economically at all, and water is the usual constraint. Small islands frequently depend on wells, rainwater collection or desalination, and in a dry summer with a full population the supply can become genuinely tight. Where signs ask visitors to be careful with water, they are not being decorative.
Waste travels in the opposite direction and has the same economics. Anything brought onto a small island has to be taken off it again, which is the practical reason that packaging is a live issue in places where it is barely discussed on the mainland.
Planning around a link that can fail
The single most useful habit is a buffer day. Never plan to leave an island on the day of an onward flight or an unrepeatable connection, and if the itinerary cannot absorb a day, choose a route with more frequent sailings instead.
The second is to check the return before booking the outbound. It is easy to find a convenient way out to somewhere and discover that the way back on the day you need runs at an hour that ruins the plan, or does not run at all in that month.
The third is to hold the alternatives in mind before you need them. Knowing whether there is a second port, a different operator, or a small aircraft link turns a cancellation from a crisis into an inconvenience, and that knowledge is worth ten minutes before departure.
Common questions
Should I book a ferry in advance or turn up?
Foot passengers on frequent routes can usually turn up outside peak periods, while vehicles nearly always need booking because deck space is genuinely limited. In high season on popular island routes, both fill, and a vehicle booking in particular can be scarce weeks ahead.
What happens to my ticket if a sailing is cancelled?
Practice varies by operator and by country, but a cancellation for weather is usually treated as a rebooking onto the next available service rather than as compensation. What it will not cover is the onward flight you missed, which is the argument for the buffer day.
Are smaller islands always more expensive?
Generally yes for goods, because the freight per item is higher and the local market is small. Accommodation does not always follow the same pattern, since a remote island with a short season and few visitors may be cheaper to stay on than a well-connected one with strong demand.
