Whether you can take beer on a ferry in 2026 depends on the carrier's consumption vs. transportation policy. For most major European ferry lines like Stena Line, P&O, or Brittany Ferries, you are allowed to transport unopened beer in your vehicle or luggage as part of your personal allowance. However, you are strictly prohibited from consuming your own alcohol in the public areas, bars, or restaurants of the ship; you are expected to purchase beverages from the onboard outlets. Some carriers may even restrict consumption in private cabins to prevent rowdy behavior. On smaller domestic ferries (like those in the US, Canada, or to various islands), policies vary; many island ferries allow you to carry a small cooler of beer for the beach, but drinking while on the vessel is often banned unless there is a licensed bar on board. Always check the "Prohibited Items" section of your ticket; if a crew member catches you drinking your own beer, they have the right to confiscate it and, in extreme cases, refuse you passage on future sailings.
