How should travellers handle ferry delays and island transfers?
Treat Greek ferries as weather-shaped transport, not fixed scenery rides. Leave slack before flights, avoid fragile same-day connections and do not make the best part of the trip depend on perfect seas.
Answer
Most ferry trips are straightforward until the one that matters is not. The practical move is to build the route so a delay is annoying rather than trip-breaking. Avoid planning an international departure on the same day as an island ferry. Be careful with late arrivals that depend on one final connection. Keep island combinations simple, especially outside the easiest summer patterns. None of this means Greece is difficult; it means the sea is part of the transport system. The more important the connection, the more boring and conservative the plan should be.
Recheck before you go
Transport schedules can change. Check current timings before you book around them.
