Book the true dimensions
Ferry systems often price vehicles by length and height bands. Include rear bike racks, roof boxes, tow bars and trailers. A six-meter motorhome with a half-meter rack should not be booked as exactly six meters if the operator measures total length.
Gas systems must follow operator rules
Propane or LPG bottles usually need to be switched off during the crossing except where the ferry has a specific policy. Some operators limit cylinder quantity or require declaration at check-in. Follow the ferry company’s safety instructions; general RV advice is not specific enough.
You may not be able to access the vehicle deck
On many crossings, passengers leave the vehicle and cannot return until arrival. Take medication, passports, chargers, warm clothing and anything needed for the voyage before the deck closes.
Overnight ferries need a sleep plan
A cabin can transform a long crossing into a useful hotel night. Some routes offer reclining seats or designated camper accommodation, while sleeping in the vehicle may be prohibited. Check the exact product; the motorhome itself may not remain accessible.
Arrive earlier than a normal car
Large vehicles can use separate check-in lanes and loading sequences. Ports are easier in daylight and with time to spare. Rushing a long motorhome through narrow terminal lanes creates unnecessary stress.
Deck clearance is real
A roof-mounted air conditioner, satellite dish or storage box can push a motorhome into another height class. Confirm the highest fixed point and lower anything designed to fold before boarding.
Weather can affect sailing
High winds can delay ferries and make large open decks uncomfortable for vehicles. Keep flexible campground plans on either side of an important crossing and avoid scheduling a non-refundable activity immediately after arrival.
Ferries can improve route efficiency
A well-chosen crossing can replace hundreds of kilometers of driving, tolls and fuel. Compare total cost, not the ferry fare alone. For routes involving the UK, Scandinavia, Mediterranean islands or New Zealand’s two main islands, the ferry can be an integral part of the road trip.
Secure the interior before boarding
Ferries can move significantly in rough seas. Close cabinets, secure loose kitchen items and empty open cups before driving onto the deck. Turn off equipment the ferry operator requires to be isolated. The vehicle may experience motion different from ordinary road driving.
Pets need their own ferry plan
Operators vary widely: some require pets to remain in the vehicle, some provide kennels and others offer pet-friendly cabins. A long overnight crossing is uncomfortable when this is discovered only at check-in. Book the pet at the same time as the vehicle and cabin.
Check road access at both ports
Some ferry terminals sit inside dense cities or industrial areas that are awkward for large motorhomes. Review the approach and exit before travel, not only the sea crossing. A late-night arrival can be easier when the first campsite or legal overnight stop is already saved. The ferry journey ends at the ramp, but the driving day may not.
Set the handbrake and follow deck instructions
Crew may request the vehicle be left in gear, with the handbrake applied and alarms disabled. Follow the specific ship’s instructions because securing procedures differ by route and sea conditions.
