Distinguish transport from a sightseeing cruise
First establish which product you are considering. A scheduled ferry between stops differs from a sightseeing cruise returning to its starting point. Ticket coverage, duration and opportunities to get off may differ. Similar views across the water do not make the two products interchangeable.
Locate the exact pier rather than only the waterfront district. Several nearby boarding points in a harbour may serve different routes. Check the berth number or meeting-point description on the official site. The walk from the nearest station to the correct gangway can be longer than the proximity of a harbour icon suggests.
Plan the sailing and shore visit together
Decide whether you want to remain aboard or get off across the water. A shore visit requires a suitable return on the correct date and in the right direction. A regular route timetable is a starting point, but short-notice changes need a separate check. HVV, for example, distinguishes line timetables from current notices and real-time information.
Do not stay until the last possible return if missing it would make the evening difficult. Check an overland alternative where one exists. Its duration and ticket requirements may differ considerably from the outward crossing. A short distance between two shores says little about the length of the land route connecting them.
Weather and operating conditions can affect services. Use current operator notices rather than assuming normal operation because the sky looks clear. The ferry should be removable from the day's plan when conditions are unsuitable, without making another important booking impossible to reach. This matters particularly when the crossing is your only planned link between activities.
Prepare for the time aboard
Bring clothing suitable for wind on an open deck, and arrange bags so your hands are available while boarding. For a pushchair, bicycle or mobility aid, check the specific carriage and access conditions. Reaching a pier does not automatically establish that the transition onto the vessel suits every traveller.
If you want to take photographs, stay within permitted passenger areas and keep boarding routes clear. Decide whether views or reaching a destination is the main purpose of the trip. A short scheduled crossing can add interest to a city itinerary without needing to fulfil every expectation of an extended harbour tour. Matching the product to that purpose makes the choice easier.
