Ferries barely appear in travel writing and appear constantly in real itineraries: the island you are staying on, the crossing between two countries, the lake transfer to the lodge. The State Department publishes maritime travel information for two thirds of the destinations it covers, which is a reasonable indication that this is a mode worth thinking about rather than turning up for.
The short version
- Overloading is the recurring risk. If the vessel is visibly overfull, do not board it.
- Find the life jackets before departure, not during.
- Weather cancels crossings, sometimes for days. Never plan one against a flight.
- An international crossing is a border. Passport, and possibly a visa.
- Check your insurance covers small-boat travel, which some policies exclude.
What You Need to Know
Two categories again
A scheduled vehicle ferry operated by a licensed company with a terminal and a manifest is a form of public transport. An unscheduled small boat that leaves when it is full, with no manifest and no safety equipment, is not, and the difference in risk between them is large. The visible test is the same as for road transport: capacity, freeboard, condition and whether the crew appears to be counting.
The specific hazard is overloading
Most serious ferry casualties worldwide involve vessels carrying more people or cargo than they were designed for, frequently in poor weather, often at night. That combination is avoidable by a passenger: decline a visibly overloaded boat, prefer daylight crossings, and prefer the operator with a terminal and a ticket over the one with a man on a jetty.
Safety equipment
Locate the life jackets before the crossing begins and make sure everyone in your party knows where they are and how to put one on. On a small boat, ask for one at boarding; a refusal or an absence is itself the answer to whether you should be aboard. Note the exits on an enclosed vessel.
Weather is the schedule
Crossings are canceled for sea state, wind and fog, sometimes at short notice and sometimes for consecutive days. On island itineraries this is the single largest planning risk: an onward international flight booked for the day after the last possible ferry is an itinerary with no margin. Build in a buffer day, or fly the leg where a flight exists.
International crossings are border crossings
A ferry between two countries is subject to the same immigration and customs process as an airport, with the same document requirements and the same consequences for arriving without a visa. Confirm entry requirements for arrival by sea specifically; they are occasionally different from arrival by air, particularly where visa-on-arrival is available at airports only.
What to Do Before Your Trip
- Read the maritime travel section of your destination’s country information.
- Book with an established operator and keep the ticket.
- Check entry requirements for arrival by sea on an international route.
- Build a buffer day before anything unmissable.
- Check your travel insurance for small-boat or watercraft exclusions.
Important Considerations
Motion sickness is a planning problem
Preventive medication taken before departure works far better than anything taken once you feel unwell, and a rough two-hour crossing can remove a day from someone’s trip. If anyone in the party is susceptible, plan for it, and see traveling with prescription medication for carrying anything across a border.
Vehicles on ferries
Taking a rental car onto a ferry, particularly an international one, is frequently prohibited by the rental agreement and can void the insurance entirely. Ask the rental company before booking the crossing, not after; see renting a car abroad.
Tips for Group Travelers
- Book as a group with the operator so the manifest is right and nobody is left on the jetty.
- Count on and count off. A boat is the easiest place to lose someone in plain sight.
- Brief everyone on life jackets and exits once, at boarding.
- Plan for a cancellation: what the group does if the crossing does not run today.
- Split expensive equipment across vessels where a group is crossing in more than one boat.
Common Mistakes to Avoid
- Boarding a visibly overloaded boat because it is the last one today.
- Planning a crossing the day before an international flight.
- Assuming visa-on-arrival applies at a sea port.
- Taking a rental car aboard without the rental company’s permission.
- Waiting until you feel ill to take motion sickness medication.
Frequently Asked Questions
Are ferries safe?
Scheduled services run by licensed operators generally are. The risk concentrates in small, unscheduled, overloaded boats, often in poor weather or after dark. Decline the visibly overfull vessel.
Do I need my passport for a ferry?
For any international crossing, yes, and possibly a visa. Check the requirements for arrival by sea specifically, which can differ from arrival by air.
What happens if the crossing is canceled?
You wait, sometimes for days. This is why a buffer day before an onward flight matters more on an island itinerary than almost anywhere else.
Can I take a rental car on a ferry?
Often not, and doing so without permission can void the insurance. Ask the rental company first.
Does travel insurance cover boat travel?
Not always, particularly for small or unlicensed craft. Check the policy wording before you rely on it.
