Will I still be able to sail to European/GB destinations via ferry from the ROI?
Brexit will not affect the ability of Stena Line ferries to sail from the ROI to GB and Europe.
Passengers travelling via Stena Line ferries to GB/ Europe should be able to continue to sail on their booked ferry services, as well as book new crossings to GB/ Europe for travel up to, during and beyond October 31st, 2019, with confidence. This will remain the case regardless of a deal or no deal Brexit scenario, although some of the requirements for travel will change depending on the Brexit outcome.
The above Q&A is based on latest government advice which may be subject to change.
