Hello Patrick,
The Irish Authorities are currently advising against all non-essential travel overseas until further notice. This also includes ferries. Also, all visitors are required to self-isolate for 14 days when they arrive to Ireland from another country.
These restrictions will be reviewed on the 9th of July for every country, so they might change for the UK. However, there is still no certainty, so we would recommend you to review
Ireland’s Department of Foreign Affairs site and our
Traveller's Health Page often. These offer updated information on the measures taken regarding travel.
We hope we get to see you soon!
David
